Attached CI results for the trunk branch. There are no regressions there. 
(Typical mix of known simulator flakes, unterminated threads in a couple AST 
tests, and unrelated upgrade test failure, etc.)

> The Memtable implementation allows it to be split into a number of shards. 
> This reduces contention during writes. 
> The MemtableIndex in SAI should follow this practice. It currently does not 
> support sharding so all writes hit the same synchronized write block. The 
> in-memory index search can also use the sharding to reduce the number of 
> indexes that it searches based on the key range passed to the search.
> This exists already in the DS fork:
