> Once an SAI index finds matches (primary keys), it reads the associated rows
> and post-filters them to incorporate partial writes, tombstones, etc.
> However, those reads are not currently updating the local table latency
> metrics. It should be simple enough to attach a metrics recording
> transformation to the iterator produced by querying local storage.
