[GitHub] [samza] shekhars-li opened a new pull request, #1648: Update RocksDB to version 7.8.3 to reduce write amplification
shekhars-li opened a new pull request, #1648:
URL: https://github.com/apache/samza/pull/1648
What: Updated RocksDB to version 7.8.3
Why: This version reduces the write compaction by aligning compaction output file boundaries. More details can be found in [this blog post](http://rocksdb.org/blog/2022/10/31/align-compaction-output-file.html). TL;DR: Write amplification was observed to be reduced by 10% by optimizing cutting the compaction output file earlier.
How: Feature is enabled by default in version 7.8.0 and above of RocksDB.
Tests: None. Past tests were re-run to verify they are still passing.
