> h2. High level design overview
> * When incremental backup request comes for tables {t} we select all the
> tables already registered in a backup system - {T} and union them with {t},
> which results in a new table set - U(t, T)
> * For every table K from U(t,T) we perform the following:
> ** Convert new WAL files into HFile applying table filter K (only edits for
> table T will pass the filter)
> ** Move these HFile(s) to backup destination
> During restore (incremental):
> * We run full restore first
> * Then collect all HFiles from intermediate incremental images and run them
> through HFileSplitterJob, which splits files into a current tables region
> boundaries
> * Load these files using LoadIncrementalHFiles tool
