v3.1.0

Warning

If the snowflake.topic2table.map parameter is configured, Snowflake recommends using this version.
We strongly recommend upgrading the connector, if you are on earlier versions 2.x, 1.9.x, and 1.8.x.

Notable Changes

• For the Snowpipe ingestion method, when the snowflake.topic2table.map parameter is configured to map multiple topics to a single table, the connector adds the topic’s salt hashCode to the stage file prefixes to avoid file collision and load data from all specified topics.
• The connector no longer throws the IndexOutOfBoundException when offsets are not continuous during schema evolution.

• NO-SNOW Improve offset logging for Snowpipe by @sfc-gh-mbobowski in #1027
• NO-SNOW speed up Iceberg schema evolution test by @sfc-gh-bzabek in #1028
