 ## Overview
 The Fluss DataStream Connector for Apache Flink provides a Flink DataStream source implementation for reading data from Fluss tables and a Flink DataStream sink implementation for writing data to Fluss tables. It allows you to seamlessly integrate Fluss tables with Flink's DataStream API, enabling you to process data from Fluss in your Flink applications.

 #### Reading from a Log Table
 When reading from a log table, all records are emitted with `RowKind.INSERT` since log tables only support appends.
