What's New

Improved Query Language UX ✨

• Pipe operator (|) to build custom SELECT with specific columns instead of default SELECT *
  • Example: namespace="prod" | namespace msg.level
  • Example: msg.level="ERROR" | timestamp msg.request.method
• Dot notation (.) to parse infinite nested JSON columns, for both WHERE and SELECT
  • Dotted notation: log_attributes.user.name = "john"
  • Quoted field support: log_attributes."user.name" = "alice"
• Type-aware SQL generation for Map, JSON, and String columns

Query History

• localStorage-based query history per team-source
• Shows last 10 recently executed queries

Enhanced Source Stats

• Table schema information with column details and types
• TTL expressions from CREATE TABLE statements
• Sort keys and primary key display
• Distributed table engine support

Improved Type Safety

• Preserve quoted literals to avoid precision loss
• Harden numeric coercion for large integers
• BigInt checks for safe integer range

Structured Error Handling

• Position-aware error reporting with line/column info
• Parser continues after errors (shows all problems at once)
• User-friendly error messages with suggestions
• Comprehensive error codes with examples
