There are many ways to get help from the Apache Flink community. The mailing lists are the primary place where all Flink committers are present. If you want to talk with the Flink committers and users in a chat, there is a IRC channel. Some committers are also monitoring Stack Overflow. Please remember to tag your questions with the flink tag. Bugs and feature requests can either be discussed on dev mailing list or on JIRA. Those interested in contributing to Flink should check out the contribution guide.

IRC

There is an IRC channel called #flink dedicated to Apache Flink at irc.freenode.org. There is also a web-based IRC client available.

The IRC channel can be used for online discussions about Apache Flink as community, but developers should be careful to move or duplicate all the official or useful discussions to the issue tracking system or dev mailing list.

Stack Overflow

Committers are watching Stack Overflow for the flink tag.

Make sure to tag your questions there accordingly to get answers from the Flink community.

Issue Tracker

We use JIRA to track all code related issues: https://issues.apache.org/jira/browse/FLINK.

All issue activity is also mirrored to the issues mailing list.
