-----------------------------------------
Summary: Append-only should stay unmaterialized without an ON
CONFLICT clause
Key: FLINK-40324
URL: https://issues.apache.org/jira/browse/FLINK-40324
Project: Flink
Issue Type: Bug
Components: Table SQL / API
Affects Versions: 2.3.0
Reporter: Gustavo de Morais
Assignee: Gustavo de Morais
FLIP-558 dropped the inputInsertOnly guard in apache Flink, so insert-only
input into a sink with a primary key now gains a SinkUpsertMaterializer and a
keyed shuffle it never had. Reachable under upsert-materialize=AUTO with
require-on-conflict=false, and under FORCE regardless. Released in 2.3.0, and
require-on-conflict is documented as non breaking change which would make this
a regression.
