Replicate table with different config

Use case: a table is bootstrapped already, however we want to test if how much perf boost partitioning a column will bring.

The only solution now is to create a new table, regenerate all the segments.

It would be better to have a way to check segment partition mechanism and repartition data if needed.

Start by examining how an already-bootstrapped table is represented and how its segments are generated. Trace the existing table-creation and segment-partitioning paths, then determine what a repartitioning workflow would need to change. Done means testing partitioning performance on the existing data without creating a separate table or regenerating all segments.
