Siying Dong ed9f5e21aa Change OptimizeForPointLookup() and OptimizeForSmallDb() (#5165) ... Summary: Change the behavior of OptimizeForSmallDb() so that it is less likely to go out of memory. Change the behavior of OptimizeForPointLookup() to take advantage of the new memtable whole key filter, and move away from prefix extractor as well as hash-based indexing, as they are prone to misuse.
