----------------------------------------
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.
