----------------------------------
Summary: Instrument the Flink JDBC connector
Key: FLINK-7689
URL: https://issues.apache.org/jira/browse/FLINK-7689
Project: Flink
Issue Type: Improvement
Components: Streaming Connectors
Affects Versions: 1.4.0
Reporter: Martin Eden
Priority: Minor
Fix For: 1.4.0
As confirmed by the Flink community in the following mailing list
[message|http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/metrics-for-Flink-sinks-td15200.html]
using off the shelf Flink sinks like the JDBC sink, Redis sink or Cassandra
sink etc does not expose any sink specific metrics.
The purpose of this ticket is to add some relevant metrics to the
JDBCSinkFunction and JDBCOutputFormat:
- Meters for when a flush is made or snapshot state is called.
- Histograms for the jdbc batch count and batch execution latency.
These would allow deeper understanding of the runtime behaviour of performance
critical jobs writing to external databases using this generic interface.
