Topics Covered
- •JSON document storage and retrieval
- •Path expressions and nested field access
- •Schema inference and evolution handling
- •Indexing strategies for JSON fields
- •Flattening nested structures for analytics
Key Takeaways
- ✓Store JSON documents without predefined schemas
- ✓Query nested fields with SQL-like syntax
- ✓Handle schema changes without migrations
- ✓Achieve columnar performance on semi-structured data
Technical Highlights
- →JSON path support: Full JSONPath expression language
- →Indexing: Automatic path-based index recommendations
- →Compression: Type-aware compression for JSON fields
- →Query pushdown: Filter evaluation at storage layer
