Snowflake Cost Optimization Strategies-Top 15 Optimization Steps

What is Snowflake?

Snowflake is a cloud-based platform where businesses can store, manage, and analyze data. Think of it as a big online storage system for companies, but much smarter and faster.

What is Snowflake Cost Optimization?

Snowflake Cost Optimization means reducing costs while using Snowflake without affecting performance. It helps businesses save money by managing storage, computing, and queries efficiently.

Why is Cost Optimization Important?

Snowflake charges based on usage (storage + computing power).
Unnecessary usage = Higher bills.
Optimizing costs helps companies use Snowflake efficiently and save money.

How to Optimize Snowflake Costs?

Choose the Right Compute Size

Snowflake uses virtual warehouses to process data.
Use smaller warehouses for simple tasks and bigger ones only when needed.

Use Auto-Suspend & Auto-Resume

Stop computing power when not in use.
Restart automatically when needed to avoid extra costs.

Store Data Efficiently

Delete old or unnecessary data.
Use compressed file formats (Parquet, ORC, Avro) to reduce storage costs.

Optimize Queries

Write efficient queries to reduce computing time.
Use query caching to reuse previous results instead of running the same queries again.

Monitor Usage & Set Budgets

Use Snowflake’s Resource Monitors to track and control spending.
Set alerts when usage crosses a limit.

Avoid Duplicate Data

Use zero-copy cloning instead of making copies.
Remove unnecessary duplicate tables.

Use External Storage When Possible

Store less-used data in cheaper cloud storage (AWS S3, Google Cloud, Azure Blob Storage) instead of Snowflake.

Snowflake Optimization Techniques

1. Warehouse Optimization

Warehouses in Snowflake are responsible for computing tasks. Optimizing them ensures that you don’t waste resources.

Choose the Right Warehouse Size
Selecting the correct warehouse size is essential. Use smaller warehouses for light workloads and increase the size only when needed. Large warehouses consume more credits, so adjusting size based on the workload can save costs.
Enable Auto-Suspend
Auto-suspend automatically turns off a warehouse when it’s not in use. This prevents unnecessary usage and helps save money. Set a low auto-suspend time, such as 1 or 5 minutes, to reduce idle costs.
Use Multiple Warehouses
Instead of running everything on a single large warehouse, divide workloads across multiple warehouses. This ensures smooth performance and avoids slowdowns due to high usage on one warehouse.

Set Minimum Clusters to One
Snowflake’s multi-cluster warehouses can scale automatically based on demand. However, keeping the minimum clusters set to one ensures that additional resources are only used when absolutely necessary.

2. Query Optimization

Queries in Snowflake consume compute resources. Writing efficient queries reduces costs and improves speed.

Reduce Query Frequency
Running the same query multiple times wastes computing power. Instead, cache query results when possible and avoid unnecessary re-execution.
Enable Query Timeouts
Long-running queries can consume excessive resources. Setting a query timeout ensures that inefficient or incorrect queries do not keep running indefinitely.
Use Query Tags
Snowflake allows tagging queries to track their resource usage. This helps identify expensive queries and optimize them for better performance.
**Avoid SELECT ***
Instead of selecting all columns from a table, fetch only the necessary columns. Selecting extra data slows down queries and increases processing costs.
Use Materialized Views
Materialized views store precomputed query results, reducing the need to process data every time a query is run. This significantly improves performance for frequently used queries.

3. Storage Optimization

Efficient data storage reduces costs and improves query performance.

Drop Unused Tables
Old and unnecessary tables take up storage space and increase costs. Regularly clean up unused tables to free up resources.
Use Transient Tables
Transient tables do not have long-term storage costs. They are useful for temporary data that doesn’t need historical backups.
Choose the Right File Format
File formats like Parquet, ORC, and Avro provide better compression and faster query performance than CSV files. Using these formats helps reduce storage costs and improve efficiency.
Lower Data Retention
Snowflake charges for storing historical data. Reducing data retention settings ensures that only necessary data is kept, reducing storage expenses.
Cluster Tables Properly
Well-clustered tables improve query speed and reduce the amount of data scanned. This makes queries run faster and cheaper.

4. Data Loading Optimization

Loading data efficiently improves performance and lowers costs.

Optimize File Size Before Loading
Instead of loading thousands of small files, combine them into larger, well-balanced files. This reduces processing time and improves performance.
Use Bulk Loading
Instead of inserting data row by row, load data in bulk. This is much faster and more cost-effective.
Avoid Frequent DML Operations
Too many INSERT, UPDATE, or DELETE operations slow down performance. Instead, batch these operations whenever possible to minimize processing overhead.

5. Monitoring and Cost Control

Regularly tracking usage helps identify inefficiencies and control costs.

Enable Snowflake Resource Monitors
Resource monitors allow you to set spending limits and receive alerts when costs are high. This helps in controlling expenses.
Use Access Controls
Restrict warehouse modifications and costly queries to only authorized users. This prevents accidental high-cost operations.
Analyze Cost Reports
Regularly review Snowflake usage and billing reports to identify areas where costs can be reduced. Understanding where resources are being consumed helps in optimizing usage.

Snowflake Cost Optimization: 15 Proven Strategies for Reducing Costs

️1.Reducing Auto-Suspend

What is it?

When a Snowflake virtual warehouse is running, it keeps using compute power, which means you keep paying for it. Auto-suspend is a feature that automatically shuts down a warehouse after a period of inactivity. If this period is too long, you waste money on unused resources.

Example

Suppose your warehouse has an auto-suspend time of 10 minutes. If no queries run for 9 minutes, the warehouse remains active and keeps charging you.
If you reduce the auto-suspend time to 1 minute, the warehouse shuts down quickly after use, saving money.

Best Practice

Set auto-suspend to 1 minute (60 seconds) for most warehouses.
Only keep longer auto-suspend times if queries run frequently.

2.Reducing the Warehouse Size

What is it?

Snowflake offers warehouses in different sizes (X-Small, Small, Medium, Large, etc.). Larger warehouses cost more. If a smaller warehouse can handle the workload, using a bigger one wastes money.

Example

A Medium warehouse costs twice as much as a Small warehouse.
If your queries run fast enough on a Small warehouse, there is no need to pay extra for a Medium warehouse.

Best Practice

Start with a smaller warehouse and increase the size only if needed.

3.Ensure Minimum Clusters Are Set to 1

What is it?

Snowflake allows multi-cluster warehouses, which add more compute power automatically when needed. If the minimum number of clusters is too high, extra clusters may run even when not needed, wasting money.

Example

If your warehouse is set to always run at least 3 clusters, but most of the time you only need 1 cluster, you are paying for 2 extra clusters unnecessarily.

Best Practice

Set the minimum clusters to 1 and let Snowflake add clusters only when needed.

4.Consolidate Warehouses

What is it?

Running too many small warehouses separately can lead to higher costs. Instead, combining workloads into fewer, slightly larger warehouses can be more cost-effective.

Example

Instead of using 5 X-Small warehouses, you could use 1 Medium warehouse.
This reduces overhead costs and improves efficiency.

Best Practice

Group similar workloads together in a single warehouse where possible.

5.Reducing Query Frequency

What is it?

Every time you run a query, you pay for compute resources. Running the same queries too often increases costs.

Example

If you refresh a report every minute, but the data only changes once an hour, you are wasting resources.
Changing the refresh rate to every hour instead of every minute will reduce costs significantly.

Best Practice

Run queries only when necessary and avoid unnecessary refreshes.

6.Only Process New or Updated Data

What is it?

Instead of reprocessing all data every time, only process new or changed records. This reduces compute costs.

Example

If your database has 1 million records and only 1,000 new records arrive daily, only process the 1,000 new records instead of reprocessing all 1 million.

Best Practice

Use incremental data processing instead of full table scans.

7.Ensure Your Tables Are Clustered Correctly

What is it?

Table clustering helps queries run faster by organizing data efficiently. Poorly clustered tables increase processing time and costs.

Example

If a table is regularly filtered by “date”, but data is not clustered by date, queries take longer to run.
Proper clustering speeds up queries and reduces compute costs.

Best Practice

Use automatic clustering or define clustering keys manually.

8.Drop Unused Tables

What is it?

Keeping old, unused tables increases storage costs.

Example

If you created test tables six months ago and never used them again, you are paying for unnecessary storage.

Best Practice

Regularly delete unused tables to reduce storage costs.

9.Lower Data Retention

What is it?

Snowflake keeps old versions of your data for a set period. Longer retention costs more.

Example

If you don’t need 30 days of history, reducing it to 7 days can cut costs.

Best Practice

Reduce retention periods based on business needs.

10. Use Transient Tables

What is it?

Transient tables do not store historical data, so they cost less than permanent tables.

Example

Use transient tables for temporary reports instead of regular tables.

Best Practice

Use transient tables for short-term data to reduce storage costs.

11. Avoid Frequent DML Operations

What is it?

Frequent INSERT, UPDATE, DELETE operations slow down performance and increase costs.

Example

Instead of updating 1 row at a time, update multiple rows together to save compute power.

Best Practice

Use batch updates instead of frequent row-by-row updates.

12.Ensure Your Files Are Optimally Sized Before Loading

What is it?

Loading very small files increases processing time. Snowflake performs better with medium-sized files.

Example

Instead of 1,000 tiny files (1MB each), use 100 files (100MB each) for faster processing.

Best Practice

Keep file sizes between 100MB – 250MB.

13.Leverage Access Control to Restrict Warehouse Usage & Modifications

What is it?

If anyone can use your Snowflake warehouse, unnecessary queries may increase costs.

Example

If junior team members run expensive queries accidentally, it wastes money.

Best Practice

Use role-based access control (RBAC) to limit warehouse access.

14. Enable Query Timeouts

What is it?

Long-running queries consume more compute power and increase costs. Query timeouts stop queries that take too long.

Example

If a query is taking 30 minutes, but normally should run in 5 minutes, setting a timeout at 10 minutes can prevent waste.

Best Practice

Set query timeouts for long-running queries.

15.Configure Snowflake Resource Monitors

What is it?

Resource Monitors track Snowflake usage and send alerts if spending gets too high.

Example

If your monthly budget is $1,000, you can set alerts when spending reaches $800, so you can take action.

Best Practice

Use Resource Monitors to set spending limits and alerts.

Why Cost Optimization is Crucial for Businesses?

Cost optimization means reducing unnecessary expenses while keeping a business running smoothly and efficiently. Every business wants to increase profits, and saving money on costs is one of the best ways to do that.

Why is Cost Optimization Important?

Saves Money

Reducing extra costs means more profit for the business.
Money saved can be used for other important things, like marketing, hiring, or product improvement.

Better Use of Resources

A business has limited money, time, and resources.
Cost optimization ensures resources are not wasted and are used where they matter the most.

Competitive Advantage

Businesses that spend less can offer better prices to customers.
This helps them stay ahead of competitors in the market.

Prepares for Uncertain Times

Economic conditions change. Sometimes, businesses face slow sales or financial problems.
A business that manages costs well can survive difficult times better than others.

Boosts Business Growth

Saving money means a business can invest in new opportunities.
It can expand to new locations, improve products, or hire skilled employees.

Improves Cash Flow

Cash flow means the money coming in and going out of a business.
Cost optimization ensures a company has enough cash to pay salaries, bills, and invest in growth.

Increases Efficiency

Businesses can remove unnecessary expenses and improve processes.
This leads to faster work, better results, and happier customers.

How Can Businesses Optimize Costs?

Use technology to automate tasks and reduce manual work.
Cut unnecessary expenses like unused software or excess inventory.
Negotiate better deals with suppliers to reduce purchasing costs.
Improve productivity so employees can do more in less time.
Monitor expenses regularly and adjust spending as needed.

How Snowflake Bills Usage?

Snowflake charges users based on two main factors

1. Compute (Virtual Warehouses)

Snowflake runs queries using virtual warehouses (which are like online computers).
The more queries you run and the larger the warehouse size, the higher the cost.
Billing is based on usage time, so if a warehouse runs for 1 hour, you are billed for that 1 hour.
To save costs, use auto-suspend (turn off warehouses when not in use).

2. Storage (Data Storage)

Snowflake stores your data in compressed format to save space.
Storage is billed per terabyte (TB) per month.
Costs depend on how much data you store and for how long.
Deleting unnecessary or old data can help reduce storage costs.

3. Additional Services (Optional Costs)

Snowflake also charges for data sharing, data transfer, and cloud services if used.
Example: If you copy data between different cloud regions, there may be extra costs.

Key Factors Influencing Snowflake Costs

1. Warehouse Size & Usage

Larger warehouses cost more.
Running warehouses for longer periods increases bills.
Use smaller warehouses for simple tasks and only increase size when needed.

2. Query Efficiency

Complex queries take longer to run, using more computing power.
Optimizing queries reduces cost by lowering warehouse usage.

3. Storage Management

Keeping unnecessary or duplicate data increases costs.
Removing old data and using external storage (AWS S3, Google Cloud, etc.) can save money.

4. Auto-Suspend & Auto-Resume

If a warehouse is not used for a while, turn it off automatically to stop billing.
This prevents unnecessary charges.

5. Data Transfer Costs

Moving data between different Snowflake accounts or cloud providers may add extra charges.
Reducing unnecessary data transfers lowers costs.

6. Using Caching

Snowflake stores query results temporarily (query caching).
If the same query is run again, Snowflake uses the cached result instead of running it again, saving compute costs.

Using Snowflake’s Serverless Features (e.g., Snowpark)

What is Serverless in Snowflake?

Serverless means you don’t have to manage or pay for servers all the time.
Snowflake automatically provides computing power when needed and stops when not needed.
This is cheaper than running a virtual warehouse all the time.

What is Snowpark?

Snowpark is a tool in Snowflake that helps run Python, Java, or Scala programs inside Snowflake.
Normally, companies use separate servers for data processing, but with Snowpark, all processing happens inside Snowflake.
This means less data movement, faster results, and lower costs.

How Does This Save Money?

No need to keep warehouses running – Snowflake starts computing power when required and stops it automatically.
No extra servers needed – Businesses don’t need to pay for separate processing servers.
Faster performance = less computing time – If data is processed quickly, costs go down.

Choosing the Right Virtual Warehouse Size

What is a Virtual Warehouse?

A virtual warehouse is Snowflake’s computing power.
Think of it like a computer that processes queries.
Larger warehouses have more power, but they cost more.

Different Warehouse Sizes

X-Small & Small – Best for simple queries and small data processing.
Medium – Good for moderate workloads.
Large & X-Large – Needed only for big data processing or complex queries.

How to Choose the Right Warehouse Size?

Use smaller warehouses for daily tasks – This keeps costs low.
Only use bigger warehouses when necessary – Avoid keeping them running for small tasks.
Auto-suspend warehouses when not in use – If a warehouse is not doing any work, it should turn off automatically.

How Does This Save Money?

If you run a large warehouse when a small one is enough, you are wasting money.
Auto-suspending stops extra billing when a warehouse is not being used.
Choosing the right size means you only pay for what you need.

Choosing the Right File Formats (Parquet, ORC, Avro)

What is a File Format?

A file format is how data is stored in Snowflake.
Different formats affect storage size and speed.

Best File Formats for Snowflake

Parquet – Best for saving space and making queries run faster.
ORC – Good for big data processing.
Avro – Great for storing raw data in JSON-like format.

How Do These Formats Save Money?

Parquet and ORC use less storage space, so you pay less for storage.
They help queries run faster, reducing compute costs.
Less data scanning means less time and less money spent on processing.

Common Challenges in Managing Snowflake Costs

Warehouses Running Unnecessarily

If warehouses stay on when not needed, you keep getting charged.
Solution: Use Auto-Suspend so they turn off when idle.

Inefficient Queries

If queries take too long, Snowflake uses more computing power, increasing costs.
Solution: Write optimized queries and use query caching (store previous query results).

Too Much Data Stored

Keeping extra, unnecessary, or duplicate data increases storage costs.
Solution: Regularly delete old or unused data.

Expensive Data Transfers

Moving data between different Snowflake accounts or cloud providers can add hidden costs.
Solution: Avoid unnecessary cross-region data transfers.

No Cost Monitoring

If businesses don’t track spending, they might overspend without realizing it.
Solution: Use Snowflake’s Resource Monitors to set spending limits and get alerts.

3 Simple Steps for Snowflake Cost Optimization

Step 1: Snowflake Warehouse Size Optimization

A Snowflake virtual warehouse is where your queries run, and it uses compute power. The larger the warehouse, the higher the cost. That’s why optimizing warehouse size is the first step in saving money.

Group Similar Workloads in the Same Virtual Warehouse

If you have different teams running similar queries, they can share the same warehouse instead of using separate ones.
Example: Instead of having three Small warehouses for reporting, ETL processing, and data analysis, you can combine them into one Medium warehouse to save money.

Leverage Data SLAs to Define Workloads and Value to Business

A Service Level Agreement (SLA) defines how important and urgent a workload is.
Example: If reports must be generated in real-time, they may need a larger warehouse. But if daily reports can run overnight, you can use a smaller, cheaper warehouse.

Start Small and Right-Size Utilization

Always start with the smallest possible warehouse and increase size only if needed.
Example: If your queries run well on a Small warehouse, upgrading to a Medium or Large is a waste of money.

Set Resource and Volume Monitors

Resource monitors help you track usage and set spending limits.
Example: You can configure Snowflake to send alerts or pause the warehouse if usage exceeds a set budget.

Step 2: Snowflake Query Optimization

Every query uses compute power, and if queries are not optimized, costs can increase quickly. Optimizing queries reduces cost and improves performance.

Using Query Tags

Query tags help you track which queries are running, who is running them, and how often they run.
Example: If a team is running the same query multiple times a day, you can optimize it or schedule it to run less frequently.

Identifying Most Expensive, Deteriorating, and Heavy Queries

Some queries take longer and consume more compute resources than necessary.
Example:
- A query that scans the entire database instead of filtering specific data is wasting resources.
- You can rewrite the query to only fetch the required data, making it faster and cheaper.

Step 3: Snowflake Table Optimization

Storage in Snowflake is cheap, but processing large tables inefficiently can increase costs. Table optimization helps reduce query costs and improve speed.

Search Optimization Service vs. Table Clustering and Materialized Views

Search Optimization Service: Helps speed up searches without scanning the entire table.
Table Clustering: Organizes data in a way that makes queries run faster.
Materialized Views: Store pre-computed query results to reduce query time.
Example: If your queries always filter data by date, clustering the table by date column can make queries run faster and cost less.

Unused Tables

If tables are not used, they still take up storage space, increasing costs.
Example: Deleting old test tables can save money on storage.

Snowflake Cost Optimization: 12 Steps

How Snowflake Calculates Costs

Before we talk about cost optimization, it’s important to understand how Snowflake charges you.

There Are Three Main Areas Where You Spend Money in Snowflake

Compute Costs (Virtual Warehouses)
- Every time you run a query (search, filter, analyze data, or update records), Snowflake uses a virtual warehouse to process the request.
- The bigger the warehouse and the longer it runs, the more you pay.
Storage Costs
- Snowflake stores all your data in the cloud.
- The more data you keep, the higher the cost.
Additional Features & Data Transfer Costs
- Snowflake offers extra features like automatic search optimization, cloning, and copying data between different regions.
- These features may add extra charges to your bill.

Now, let’s look at how to reduce these costs and save money.

Keep Your Bill Under Control With These 12 Snowflake Cost Optimization Tips

There are four major ways to reduce Snowflake costs

Optimizing Virtual Warehouses
Optimizing Queries
Optimizing Tables
Monitoring Costs and Usage

Warehouse Optimization How to Use Virtual Warehouses Efficiently

A virtual warehouse in Snowflake is like a kitchen in a restaurant. If you open a large kitchen for just a few customers, you waste resources and money. Similarly, if you keep warehouses running all the time, you pay for unnecessary compute time.

1. Use Multiple Warehouses Instead of One Large One

Instead of using one large warehouse for everything, you can create multiple warehouses based on workload.
This helps in efficient cost control and better performance management.
Example
- A small warehouse for basic daily reports.
- A medium warehouse for business analytics.
- A large warehouse only when running complex data processing tasks.

2. Choose the Right Warehouse Size

A bigger warehouse runs queries faster, but it also costs more money.
Always start with a small warehouse and increase the size only when necessary.
Example
- If a small warehouse can handle your daily reporting, there’s no need to pay extra for a larger one.

3. Use Auto-Suspend to Shut Down Unused Warehouses

Snowflake allows you to set warehouses to turn off automatically when they are not in use.
Example
- If you set auto-suspend to 5 minutes, your warehouse shuts down after 5 minutes of no activity, saving money.

4. Keep Minimum Clusters to One

Snowflake has a multi-cluster feature that allows warehouses to add extra clusters when needed.
However, if you don’t need multiple clusters, keeping them at a minimum (1) saves costs.
Example
- Instead of keeping 4 clusters active all the time, set it to just 1 and increase it only if needed.

Query Optimization: Running Queries Efficiently to Save Money

Running queries costs money because they consume computing power. If you run unnecessary or repeated queries, you waste money.

5. Reduce the Frequency of Queries

Instead of running the same query multiple times a day, try reducing the frequency.
Example
- If a report is only used once a day, there’s no need to run it every hour.

6. Enable Query Timeouts

Some queries run for a long time and use too much power. Snowflake allows you to set a time limit to automatically stop these queries.
Example
- If a query takes more than 10 minutes, you can set a timeout to stop it automatically, saving costs.

7. Use Metadata Tags on Queries

Metadata is extra information attached to queries that helps track who is running them and why.
Example
- If you see test queries running on a large warehouse, you can stop them to avoid wasting money.

Table Optimization: Managing Storage Costs Efficiently

8. Delete Unused Tables

Old, unnecessary tables still take up space, and you get charged for storing them.
Example:
- If you have test data from last year, delete it to free up space and reduce storage costs.

9. Use Transient Tables for Temporary Data

If you only need a table for a short time, use transient tables instead of permanent ones.
Example:
- A table that stores daily logs can be a transient table instead of a regular table, reducing storage costs.

10. Avoid Too Many Small Updates or Deletes (DML Operations)

INSERT, UPDATE, and DELETE operations use a lot of processing power if done too frequently.
Example
- Instead of updating data row by row, batch updates together to run fewer queries and save money.

Monitoring and Cost Visibility Tracking and Controlling Snowflake Costs

11. Set Up Snowflake Resource Monitors

Snowflake allows you to set up monitors that can alert or stop warehouses if they are using too much compute power.
Example
- If a warehouse reaches 80% of its budget, a monitor can stop it from running more queries.

12. Use Cloud Zero or Other Cost Tracking Tools

Cloud Zero is a tool that tracks your Snowflake costs and helps you understand where your money is going.
Example
- If you see one department using too many expensive queries, you can talk to them and find ways to reduce costs.

Conclusion

Managing Snowflake costs is easy when you follow simple and smart strategies.
