Hello! Is it safe to change RocksDB settings without removing state stores data? We would like to tune RocksDB for our Kafka Streams applications by changing the following properties:
- rocksdb.max\_write\_buffer\_number
- rocksdb.min\_write\_buffer\_number\_to\_merge
- rocksdb.lru\_cache
- rocksdb.optimize\_for\_point\_lookup
- rocksdb.write\_buffer\_size
- rocksdb.write\_buffer\_size\_allow\_stall
- rocksdb.total\_write\_buffer\_size
- rocksdb.lru\_cache\_highPriPoolRatio
- rocksdb.max\_background\_compactions
- rocksdb.level0\_file\_num\_compaction\_trigger
- rocksdb.level0\_slowdown\_writes\_trigger
- rocksdb.level0\_stop\_writes\_trigger
- rocksdb.num\_levels
- rocksdb.max\_bytes\_for\_level\_base
If itโs safe to change these properties without purging state stores data, will it adapt to this properties so we can see a performance improvement?
Thank you in advance for answers ๐

Yes, this should be safe.
