Review Comment:
I wonder if instead of caching we can do a bit different.
The strategy is only actually used when a partition gets created, on the
common "already exists" path it's built and thrown away.
Instead of caching it, you could pass tableInfo into
checkAndCreatePartitionAsync and resolve getAutoPartitionStrategy() inside the
create branch.? Then the cached field + its thread-safety reasoning aren't
needed at all
WDYT?
