Revision 885b1c682e85391beb7f26a842e2128e3653bd4a authored by Siying Dong on 14 September 2017, 22:41:19 UTC, committed by Facebook Github Bot on 14 September 2017, 22:41:49 UTC
Summary: Move uncommon code paths in RangeDelAggregator::ShouldDelete() and IterKey::EnlargeBufferIfNeeded() to a separate function, so that the inlined strcuture can be more optimized. Optimize it because these places show up in CPU profiling, though minimum. The performance is really hard measure. I ran db_bench with readseq benchmark against in-memory DB many times. The variation is big, but it seems to show 1% improvements.
