Version 2.0.1 (August 25, 2023)
New Features and Updates
- Improved performance for schematization permission checks during rebalance.
Bug Fixes
- Fixed a bug that caused missing data in tables due to issues with internal cache clearing during rebalancing.
Version 2.0.0 (July 31, 2023)
New Features and Updates
- Snowpipe Streaming with Kafka Connector is now Generally Available.
Bug Fixes
Version 1.9.4 (July 13, 2023)
New Features and Updates
- One client configuration:
- Introduced the enable.streaming.client.optimization option, which is enabled by default.
- With this client optimization, only one client is created for multiple topic partitions per Kafka connector. This feature can reduce client runtime and lower migration cost by creating larger files.
- Note that in a high throughput scenario (for example, 50 MB/s per connector), we recommend that you disable this property if you see an increase in latency or costs.
- Permissions and security:
- Unified Snowflake role and user for Snowpipe Streaming for table creation and insertion.
- Upgraded guava dependency to 32.0.1.
- Upgraded Snowpipe Streaming SDK dependency to 2.0.1.
Bug Fixes
- Fixed a wrong result issue that offsets are skipped when schematization is enabled.
- Snowpipe Streaming Channels are not closed on rebalance.
