> TabletLocator already exists, but isn't officially a part of the "public API" and is
clunky for users to invoke. In trying to co-locate external processes with the tabletservers
that are hosting some data, it would be nice to have some means that users can invoke that
will return them these assignments.
> Memory concerns are an issue for tables with many splits (e.g. avoiding creating a Set
of 100k tablet locations for a table), but we also want to provide the ability to ask pointed
questions. Likely building something that accepts a Range (or Collection<Range>) would
be best.
