> [State TTL] Consider setting a default background cleanup strategy in

> ------------------------------------------------------------------------------------

> Key: FLINK-12476
> URL: https://issues.apache.org/jira/browse/FLINK-12476
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / State Backends
> Affects Versions: 1.8.0
> Reporter: Andrey Zagrebin
> Assignee: vinoyang
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.8.0, 1.9.0
>
>
> At the moment we have two efficient background cleanup strategies:
> incremental for heap and compaction filter for RocksDB. *StateTtlConfig* has
> 2 methods to activate them: *cleanupIncrementally* and
> *cleanupInRocksdbCompactFilter*. Each is activated only for certain backend
> type and inactive for other. They have different tuning parameters.
> The idea is to add method *cleanupInBackground* which would activate both of
> them with default parameters. User does not need to think then about details
> or used backend if not needed. Depending on actually used backend, the
> corresponding cleanup will kick in. Sample implementation:
>
> {code:java}
> public Builder cleanupInBackground() {
> return cleanupIncrementally(10,
> false).cleanupInRocksdbCompactFilter(1000L);
> }
> {code}
> We can also deprecated the parameterless *cleanupInRocksdbCompactFilter()* in
> favour of this new method.
