Inside Tableflow GA: Real-Time Kafka to Iceberg

What this post added

This post announces the General Availability (GA) of Confluent Tableflow for Apache Iceberg, detailing its integration with Snowflake Open Catalog. It explains how Tableflow materializes Kafka topics into Iceberg tables stored in object storage (e.g., S3) by converting Kafka segments and schemas (Avro, JSON, Protobuf) into Iceberg-compatible schemas and Parquet files, leveraging Confluent Schema Registry. Key capabilities highlighted include automated schema evolution, catalog syncing with Snowflake Open Catalog, table maintenance (compaction, snapshot expiration), and flexible storage options. The post also describes the process of configuring Tableflow and integrating it with Snowflake Open Catalog for seamless data discovery and querying by analytical engines like Snowflake Cortex AI.
