             Summary: Create a file-based Upsert sink for testing internal components
                 Key: FLINK-27527
                 URL: https://issues.apache.org/jira/browse/FLINK-27527
             Project: Flink
          Issue Type: New Feature
          Components: Connectors / Common
    Affects Versions: 1.16.0
            Reporter: Alexander Preuss


There are a bunch of tests that in order to ensure correctness of their tested component rely on a Sink providing upserts. These tests (e.g. test-sql-client.sh) mostly use the ElasticsearchSink which is a lot of overhead. We want to provide a simple file-based upsert sink for Flink developers to test their components against. The sink should be very simple and is not supposed to be used in production scenarios but rather just to facilitate easier testing.
