It seems like the buffer clean-up mechanism already was improved as a part of
[IGNITE-13126] Refactor of Continuous Query buffers to reduce heap usage - ASF
JIRA (apache.org)
> Excessive use of memory in continuous queries
> ---------------------------------------------
>
> Key: IGNITE-11970
> URL: https://issues.apache.org/jira/browse/IGNITE-11970
> Project: Ignite
> Issue Type: Bug
> Reporter: Igor Belyakov
> Assignee: Mikhail Petrov
> Priority: Critical
> Labels: ise
> Time Spent: 3h 10m
> Remaining Estimate: 0h
>
> When we prepare to send an entry into the continuous query's filter and
> listener, we store it in an instance of CacheContinuousQueryEventBuffer.Batch.
> The batch is an array of entries of size
> IGNITE_CONTINUOUS_QUERY_SERVER_BUFFER_SIZE (default is 1000) that stores the
> currently received entries (we need it for the case of concurrent updates to
> make sure that we preserve the order of update counters).
> The issue is that when we process a part of the array we keep the links to
> the processed entries until we exhaust the array (after when we finally clear
> it). Because of that we may store up to 999 garbage objects which can be a
> lot if the entries are big.
> Need to clear the entries right after we've processed them.
