Yu Li updated FLINK-14926:
--------------------------
Release Note: After FLINK-14926, we have introduced RocksDBOptionsFactory
and ConfigurableRocksDBOptionsFactory interfaces to better handle RocksObject
created in PredefinedOptions and customized factories. The old OptionsFactory
and ConfigurableOptionsFactory interfaces are deprecated and planned to be
removed in the future.
Adding release note about deprecation of {{OptionsFactory}} and
{{ConfigurableOptionsFactory}}, as well as the newly introduced
{{RocksDBOptionsFactory}} and {{ConfigurableRocksDBOptionsFactory}} interfaces.
> Make sure no resource leak of RocksObject

> When investigating FLINK-14484 to allow setting {{WriteBufferManager}} via
> options, we find it necessary to supply a {{close}} method in
> {{OptionsFactory}} to make sure resources configured in options like
> {{WriteBufferManager}} could/would be released.
> What's more, we're having potential risk of resource leak in
> {{PredefinedOptions}} such as the created [BloomFilter
> instance|https://github.com/apache/flink/blob/e14bd50fed42e89674ba9d01a231d5c5e59f490c/flink-state-backends/flink-statebackend-rocksdb/src/main/java/org/apache/flink/contrib/streaming/state/PredefinedOptions.java#L155]
> is never closed (regression caused by FLINK-7220 changes), and we should
> also fix this and add a {{close}} method in {{PredefinedOptions}}
