------------------------------------
Summary: Make SimpleCounter thread-safe.
Key: FLINK-12681
URL: https://issues.apache.org/jira/browse/FLINK-12681
Project: Flink
Issue Type: Improvement
Reporter: Piyush Goyal
While adding metrics to Elasticsearch connector we noticed that the
SimpleCounter which seems like the main implementation of Counter interface is
not thread-safe. It makes it tricky/expensive to use it in a multi-threaded
context.
It should be a very simple change to make it thread-safe, and the performance
benefit (if any) of keeping it thread-unsafe doesn't seem worth the extra care
to use it in a multithreaded context. What do you think ?
