What
This change improves the performance of metadata queries in the Snowflake destination connector by optimizing how table information is retrieved and processed.
How
information_schemawithSHOW TABLESandDESCRIBE TABLEcommands for faster metadata retrieval. This should also reduce the cost for customers by reduce the use of warehousesgetFinalTableRowCount,findExistingTables, andgetTableto use the new querying approachReview guide
SnowflakeDestinationHandler.ktSnowflakeV1V2Migrator.ktSnowflakeInternalStagingLowercaseDatabaseTypingDedupingTest.ktUser Impact
Users should experience faster sync operations, especially for connections with a large number of tables or columns. This optimization reduces the time spent on metadata queries, leading to improved overall performance.
