      Overview

      A MySQL data sink can write data to the MySQL database.

      Notes

      Primary key

      All data generated by an ETL data source table is UPSERT data, so it's important that you correctly define the primary key for the MySQL database table.

      WITH parameters

      MySQL data sinks are developed based on JDBC and support the following sink-related configurations:
      Parameter
      Required
      Default Value
      Description
      sink.buffer-flush.max-rows
      No
      100
      The maximum size of buffered records before flush. If this is set to 0, data will not be buffered.
      sink.buffer-flush.interval
      No
      1s
      ‍The maximum interval (ms) between ‍flushes. If sink.buffer-flush.max-rows is 0, and this parameter is not, buffered actions will be processed asynchronously.
      sink.max-retries
      No
      3
      The maximum number of retries allowed when a write operation fails.
