> RocksDB provides an API for creating SST files and ingesting them directly
> into RocksDB:
> [https://github.com/facebook/rocksdb/wiki/Creating-and-Ingesting-SST-files]
> Using this method for bulk loading data into RocksDB may provide a
> significant performance increase, specifically for paths doing inserts such
> as full savepoint recovery and state migrations. This is one method of
> optimizing bulk loads, as described in
> https://issues.apache.org/jira/browse/FLINK-17288
> This was discussed on the user maillist:
> [http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/RocksDB-savepoint-recovery-performance-improvements-td35238.html]
> A draft PR is here: [https://github.com/apache/flink/pull/12345/]
