After migrating C* from 2.1.2 to 3.0.8, all queries with the where condition involved ad indexed column return zero rows for the old data, instead news inserted data are returned from the same query, I'm guessing that something was remained incomplete about indexes, should we run rebuild indexes? Any idea? Thank Ad.
