Hi Josh, First, thanks for the response.
As far as I can tell, a disabled index cannot be directly changed to USABLE. It must be rebuilt first. I am aware that I can do ALTER INDEX .... REBUILD. But, if I understand correctly, this is single thread and slow. I'm wondering if I can use the IndexTool map reduce job in this case. About TTL, I did some experiments. Turns out that Phoenix do not automatically remove index entry when the table entry dies from TTL setting. However, it is possible to set index table with same TTL so that index can be in sync.
