-----------------------------------------
Summary: Event sink memory leak
Key: IGNITE-26251
URL: https://issues.apache.org/jira/browse/IGNITE-26251
Project: Ignite
Issue Type: Bug
Reporter: Vadim Pakhnushev
Assignee: Vadim Pakhnushev
When cluster configuration listener is invoked in the
{{ConfigurationBasedSinkRegistry}} with the same sink configuration, old sinks
are not stopped leading to possible memory leaks, for example, in the
{{WebhookSink}} there's a forever running executor with a task that captures
{{this}} and, in turn, {{clusterIdSupplier}} which is actually {{IgniteImpl}}
instance.
The solution is to stop old sinks regardless of whether they are present in the
new configuration or not.
