--------------------------------------
Summary: Remove references to disableDataSync in RocksDB
documentation
Key: FLINK-30751
URL: https://issues.apache.org/jira/browse/FLINK-30751
Project: Flink
Issue Type: Bug
Components: Documentation
Affects Versions: 1.16.0
Reporter: David Christle
The EmbeddedRocksDBStateBackend allows configuration using some predefined
options via the .setPredefinedOptions method. The documentation for
PredefinedOptions
([link|https://nightlies.apache.org/flink/flink-docs-master/api/java/org/apache/flink/contrib/streaming/state/PredefinedOptions.html])
mentions setDataSync is called for {{FLASH_SSD_OPTIMIZED}} and
{{SPINNING_DISK_OPTIMIZED}}.
But this option was removed several years ago in RocksDB 5.3.0
([link|https://github.com/facebook/rocksdb/blob/main/HISTORY.md#530-2017-03-08]),
and according to the code
[PredefinedOptions.java|https://github.com/apache/flink/blob/0bbc7b1e9fed89b8c3e8ec67b7b0dad5999c2c01/flink-state-backends/flink-statebackend-rocksdb/src/main/java/org/apache/flink/contrib/streaming/state/PredefinedOptions.java#L72],
it is no longer actually set in Flink.
We should remove references to disableDataSync in PredefinedOptions.java, and
in state_backend.py, so that it does not appear in the documentation.
