Ariel Weisberg commented on CASSANDRA-13425:
--------------------------------------------

I added some questions. Seems reasonable enough although there are some n ^ 2 array list removal steps. The question is do we ever work with enough tables for it to matter and how long can this take before it's too long? 

I also wonder if it's an issue placing these new tables in the highest level since it means new updates will take even longer to reach them.

> Currently {{nodetool refresh}} sets level to 0 on all new sstables, instead we could try to find gaps in the existing leveling and insert them there.
