Description

The EmbeddedRocksDBStateBackend allows configuration using some predefined options via the .setPredefinedOptions method. The documentation for PredefinedOptions (link) mentions disableDataSync is called for FLASH_SSD_OPTIMIZED and SPINNING_DISK_OPTIMIZED.

 

But this option was removed several years ago in RocksDB 5.3.0 (link), and according to the code PredefinedOptions.java, 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.
