Rationale
Currently CeresDB will store aligned time range when write SST, this will cause IO amplification for certain query.
For example, the SST only contains one row, and its timestamp is 10:01, its time range in metadata will be aligned to
[10:00, 12:00)
, if query contains filter liketimestamp > 10:01
, currently query plan will include this SST, but in fact we could skip this SST to avoid unnecessary IO.Detailed Changes
