Review Comment:
Would be good to read the data in the table after. Think it would be good
to run this test twice with an additional iterator. Run the test with an
additional iterator that filters a subset of data and after the compaction
verify it was filtered. Run the test another time with an additional iterator
that filters all data and verify the scan is empty and the tablet has no files.
