Summary: Remove limitation about JDBC exactly once sink about multiple connections per transaction Key: FLINK-23876 URL: https://issues.apache.org/jira/browse/FLINK-23876 Project: Flink Issue Type: Improvement Components: Connectors / JDBC, Documentation Affects Versions: 1.14.0 Reporter: Roman Khachatryan Fix For: 1.14.0 [https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/connectors/datastream/jdbc/#jdbcsinkexactlyoncesink] says:{quote}Attention: In 1.13, Flink JDBC sink does not support exactly-once mode with MySQL or other databases that do not support multiple XA transaction per connection. We will improve the support in FLINK-22239.{quote} In FLINK- connection pooling was added so this limitation doesn't apply anymore. So this should be removed or replaced with a list of databases. Connection pooling should be enabled explicitly: should list DBs requiring this (mysql, postgres) and give an example code. -- This message was sent by Atlassian Jira (v8.3.4#803005)
