connector-config
by treasure-data
Writes connector_config for segment/journey activations using tdx connection schema <type> to discover available fields. Use when configuring activations - always run schema command first to see connector-specific fields.
rt-config
by treasure-data
Configure RT 2.0 (Real-Time Personalization) for parent segments including event tables, key events, RT attributes, and ID stitching using tdx ps rt commands or API
agent-prompt
by treasure-data

rt-config-id-stitching
by treasure-data
Configure RT 2.0 ID stitching - merge real-time profiles across different identifiers using stitching keys and primary keys
trino-optimizer
by treasure-data
TD Trino performance optimization including CTAS (5x faster), UDP bucketing for ID lookups, magic comments for join distribution, REGEXP_LIKE vs LIKE, and approx functions.
hive
by treasure-data
TD Hive SQL with TD-specific functions and Hive-only features (lateral view, explode, MAPJOIN hint). Use when Trino memory errors occur or for Hive-specific syntax.
parent-segment-analysis
by treasure-data
Query and analyze CDP parent segment database data. Use tdx ps desc -o to get output database schema, then query customers and behavior tables. Use when exploring parent segment data, building reports, or analyzing customer attributes and behaviors.
rt-config-events
by treasure-data
Configure RT 2.0 event tables and key events - define which streaming events to track and filter for real-time processing
typescript
by mintuz
