> Ok. I agree we could replace MemoTable with something better. However, we don't want to have a dependency on Abseil, so it will have to be reimplemented. Yes. I'll implement one using `xsimd` as you suggested. Also the swiss table may be worse than `MemoTable` on super small tables, since it checks 8 slots at once and reserves at least 8 slots on construction, as shown in the first two string benchmarks. We'll need further benchmarking to decide which hashtable to use in each individual use cases, or maybe with a dynamic dispatching mechanism. -- This is an automated message from the Apache Git Service.
