Option B looks promising, but I'm worried it might cause some unexpected side effects. Better stick with the good old ALTER INDEX REBUILD.

I'm going with option D. Reorganizing the index sounds like a more efficient way to optimize the compression, without the need for a full rebuild.

Hmm, I'm not sure about that. Wouldn't DBCC DBREINOEX be better since it's designed for compressing column store indexes?

I think option A is the correct answer. Rebuilding the index should maximize the column store compression for table1.
