Snowflake Semi Structured Data
Snowflake semi-structured data allows you to store, query, and analyze JSON, XML, Avro, and Parquet files directly—without complex schema definitions or pre-processing.It enables faster analytics, flexible data modeling, and real-time insights at scale.
What Is Semi-Structured Data in Snowflake?
Definition
Semi-structured data is data that doesn’t follow a fixed table-like format, but still has some structure built into it.It sits comfortably between structured and unstructured data.
In Snowflake, semi-structured data can be stored, queried, and analyzed without defining a rigid schema upfront. This is known as schema-on-read, meaning you decide how to interpret the data when you query it, not when you load it.
Semi-Structured vs Structured vs Unstructured (Quick Comparison)
Data Type | What It Looks Like | Schema Requirement | Example |
Structured | Rows & columns | Fixed schema before load | Relational tables |
Semi-Structured | Key-value pairs, nested fields | Flexible, schema-on-read | JSON, XML |
Unstructured | No defined structure | No schema | Images, videos, PDFs |
In simple terms:
- Structured data is rigid but predictable
- Semi-structured data is flexible but queryable
- Unstructured data is flexible but hard to analyze
Snowflake is optimized to handle semi-structured data at scale, which is why it’s widely used in cloud-native and real-time analytics platforms.
Why Semi-Structured Data Matters in Snowflake
Modern data rarely comes in clean rows and columns. Snowflake is designed for:
- APIs that change fields over time
- Event-driven applications
- Streaming and big data workloads
- Rapid ingestion without transformation delays
With Snowflake, you can:
- Load data as-is
- Store it in a VARIANT column
- Query only what you need, when you need it
This reduces ingestion complexity and speeds up analytics.
Examples of Semi-Structured Data
Data Type | Example | Common Source |
JSON | API responses | Web & mobile apps |
XML | Configuration files | Legacy systems |
Parquet | Columnar files | Big data pipelines |
Avro | Streaming records | Kafka |
Search-friendly insight:
Snowflake natively supports JSON, XML, Avro, Parquet, and ORC, allowing teams to analyze data from APIs, logs, streams, and data lakes in a single platform.
How Snowflake Handles Semi-Structured Data (At a High Level)
Snowflake stores semi-structured data using the VARIANT data type, which:
- Preserves the original structure
- Supports nested and array-based data
- Enables SQL-based querying without flattening upfront
- This approach gives teams flexibility without sacrificing performance.
When Should You Use Semi-Structured Data in Snowflake?
Use semi-structured data when:
- Your data schema changes frequently
- You ingest data from external systems
- You want faster time-to-insight
- You want to avoid complex ETL pipelines
How Snowflake Handles Semi-Structured Data
Snowflake is designed to work natively with semi-structured data, which means you don’t need to force complex data into rigid tables upfront. Instead, Snowflake lets you load, store, and query data as it arrives, while still giving you full SQL power.
This flexibility is critical in modern data platforms where data often comes from APIs, event streams, logs, and third-party tools.
VARIANT Data Type Explained
At the core of Snowflake’s semi-structured data capabilities is the VARIANT data type.
What is VARIANT?
VARIANT is a special Snowflake data type that can store JSON-like hierarchical data, including:
- Nested objects
- Arrays
- Key-value pairs
- Mixed data types
Think of VARIANT as a smart container that understands the structure of your data without enforcing strict columns.
Schema-on-Read Concept
Snowflake follows a schema-on-read approach for semi-structured data.
What does schema-on-read mean?
- You don’t define the schema before loading data
- Raw data is ingested first
- Structure is applied only when you query the data
This is the opposite of traditional databases, which require schema-on-write (fixed columns before load).
Why this matters
- Faster ingestion
- No data loss due to schema mismatch
- Easy handling of evolving data structures
Perfect for agile analytics, streaming data, and Data Vault architectures.
Why VARIANT Is Powerful
The VARIANT data type gives Snowflake a major advantage over traditional warehouses.
Key benefits of VARIANT
- Flexible ingestion – Load data without preprocessing
- Handles schema evolution – New attributes don’t break pipelines
- Native querying – Use SQL to access nested fields
- High performance – Optimized storage & pruning under the hood
- Future-proof – Ideal for APIs, IoT, and event-driven systems
In simple terms: VARIANT lets you store first, model later—without sacrificing performance.
Supported Semi-Structured Formats in Snowflake
Snowflake natively supports multiple industry-standard semi-structured formats, making it easy to integrate with modern data sources.
JSON (Most Common)
JSON is the most widely used semi-structured format.
Why JSON works great in Snowflake:
- Directly loads into VARIANT
- Easy to query with dot & bracket notation
- Ideal for APIs, logs, SaaS tools, and event streams
Most Snowflake semi-structured use cases start with JSON.
XML
Snowflake supports XML through the VARIANT type.
Common XML use cases:
- Legacy systems
- Enterprise applications
- B2B data exchanges
XML can be parsed and queried similarly to JSON after ingestion.
Avro
Avro is a schema-based binary format, commonly used with Kafka.
Why Avro matters:
- Compact and efficient
- Strongly typed
- Ideal for streaming pipelines
Snowflake automatically converts Avro into VARIANT during ingestion.
Parquet
Parquet is a columnar file format designed for high-performance analytics workloads.
Key benefits include:
- High compression efficiency, reducing storage costs
- Faster query performance due to column-based storage
- Wide adoption in data lakes such as Amazon S3, Azure ADLS, and Google Cloud Storage
Snowflake can directly ingest Parquet files while retaining complex and nested data structures, making it ideal for analytics on semi-structured data.
ORC
ORC (Optimized Row Columnar) is another analytics-optimized format.
Used mainly for:
- Hadoop ecosystems
- Large-scale batch analytics
Snowflake supports ORC for seamless migration from legacy big data platforms.
Why This Matters for Modern Data Teams
Snowflake’s support for VARIANT + multiple formats means:
- No rigid upfront modeling
- Faster onboarding of new data sources
- Easier integration with modern tools
Better support for real-world, messy data
Loading Semi-Structured Data into Snowflake
Querying semi-structured data is one of Snowflake’s biggest strengths. Whether your data comes from APIs, event streams, or SaaS tools, Snowflake allows you to query JSON, XML, Avro, and Parquet data directly—without complex preprocessing.
In this section, we’ll break down how to read, transform, and filter semi-structured data in a simple and practical way, using real-world Snowflake features.
Accessing JSON Using Dot & Bracket Notation
Snowflake stores semi-structured data inside the VARIANT data type. Once the data is loaded, you can query it using dot notation or bracket notation—no schema changes required.
Dot Notation
Dot notation is ideal when:
- JSON keys are simple
- Field names don’t contain spaces or special characters
Use case: Access nested attributes inside JSON objects.
Example (Conceptual):
- event:user.id
- order:customer.name
- Easy to read
- Cleaner queries
- Preferred for analytics & reporting
Bracket Notation (More Flexible)
Bracket notation is used when:
- JSON keys contain spaces, hyphens, or special characters
- Keys are dynamic or unpredictable
Example (Conceptual):
- payload[‘user-name’]
- data[‘2024_metrics’]
- Handles complex keys
- Saferfordynamic
- JSON
- Slightly less readable
FLATTEN Function Explained
Semi-structured data often contains arrays—lists of values inside JSON. Snowflake’s FLATTEN function converts these arrays into rows, making them easy to analyze.
Why Flattening Matters
Without flattening:
- Arrays remain nested
- Filtering and aggregations become difficult
- BI tools struggle to consume the data
With FLATTEN:
- Each array element becomes a row
- Data becomes relational and analytics-friendly
- Joins, filters, and aggregations become straightforward
When to Use FLATTEN
Use FLATTEN when:
- Your JSON contains arrays (events, items, logs)
- You need row-level analysis
- You want to join array elements with other tables
Common real-world scenarios:
- Event tracking data (user actions)
- Order items inside e-commerce transactions
- API responses with repeated structures
Common Query Use Cases (Quick Reference)
Task | Snowflake Feature Used |
Extract nested values | Dot / Bracket Notation |
Convert arrays into rows | FLATTEN |
Filter JSON attributes | WHERE clause |
This table acts as a quick decision guide when working with semi-structured data in Snowflake.

Common Challenges & Best Practices
Working with semi-structured data in Snowflake (especially JSON) is powerful—but it comes with its own set of challenges. In this section, we’ll break down the most common problems data teams face and the best practices you should follow to keep performance high and costs under control.
Challenges
1️ Large Nested JSON Structures
The Challenge:
Semi-structured data often arrives as deeply nested JSON, with multiple levels of objects and arrays. While Snowflake can store this easily using the VARIANT data type, querying deeply nested structures can become complex and slow.
Why it matters:
- Queries become harder to read and maintain
- Extracting values requires long dot or bracket notation
- Overusing FLATTEN on large JSON can explode row counts
Real-world impact:
Data engineers spend more time debugging queries, and analytics teams experience slower dashboards.
2️ Query Performance Issues
The Challenge:
Poorly designed queries on semi-structured data can lead to:
- Full table scans
- Excessive use of FLATTEN
- High CPU and memory usage
Why it matters:
Snowflake charges based on compute usage, not just storage. Inefficient queries directly increase costs.
Common causes:
- Flattening entire JSON documents instead of specific paths
- Not filtering data before flattening
- Querying raw JSON repeatedly instead of curated views
3️Cost Optimization Difficulties
The Challenge:
Semi-structured data queries can unintentionally consume large warehouses for longer durations, leading to higher Snowflake credits usage.
Why it matters:
Without proper optimization:
- Costs grow silently
- Finance teams lose predictability
- ROI on data platforms decreases
Best Practices
1️ Use Selective FLATTEN
Best practice:
Always flatten only what you need, not the entire JSON document.
Why it works:
- Reduces row explosion
- Improves query performance
- Lowers compute consumption
Tip:
Apply filters before or inside the FLATTEN clause whenever possible.
2️.Partition Data Properly
Best practice:
Organize your data using:
- Logical partitions (e.g., date, source system)
- Separate raw and curated layers
Why it works:
- Limits the amount of data scanned per query
- Improves pruning efficiency
- Makes data pipelines easier to scale
Example use cases:
- Partition event data by ingestion date
- Separate high-volume JSON feeds into dedicated tables
3️ Optimize Warehouse Size
Best practice:
Match your warehouse size to your workload.
How to do it right:
- Use smaller warehouses for exploratory queries
- Scale up only for heavy transformations
- Enable auto-suspend to avoid idle costs
Why it works:
Snowflake’s elastic compute allows you to pay only for what you use—but only if warehouses are sized correctly.
