> All of our client operations work by table name. This present awkward cases around renames.
A solution to this is making all operations work around table IDs, but this isn't user friendly.
A middle ground is introducing a TableHandle, which is a container for the user to use, with
the implication that if a rename happens, the operations will follow the table. This is similar
to how filesystems deal with renames.
> This way we have the translation between table name->id done VERY early on and done
explicitly to the users knowledge so they can make guarantees about operations.
> I would see there being an operation added for getTableHandle which takes the name and
then that handle is used for all future operations.
> By putting things in a TableHandle, we can have a minor first pass which ges the API
in place and then we can work on ensuring no name->id mapping occurs deeper in the server
to help make sure things are consistent.
