I can't find this in the docs, but IIRC the merge command can take a
start/end range for what to merge. So the best option might be to try it on
a smaller slice and see what happens. At a guess, queries won't block but
indexing will.

That looks like a great option. Before using it, whats the cost/impact of
running this on a massive table in a system with other large bulk

Just to clarify: compactions don't implicitly change the table
"distribution". The number and/or boundaries of tablets don't change as
a part of a compaction.

I have a table that has evolved to have 1.07T tablets and I fairly confident a
large portion of these are now empty or very small. I'd like to merge smaller
tablets and delete empty tablets, is there a smart way to do this?
My thought was to query the metadata table for all tablets
