I took this up as a low hanging fruit, agree with not focusing on micro-benchmarks comment. This was just a curiosity / exploratory effort from me that took all of 20 mins including the fix so went ahead with the patch. was (Author: swagle): [~aengineer] Yes the follow-up Jira will not be blindly taken up without figuring out if 10s of RocksDBs sharing a disk vs 1 RocksDB with 10 tables in a single RocksDB which one is better/worse.
