The table has 24 sstables with size tiered compaction, when I run nodetool
tablehistograms I see 99% percentile of the queries are showing up 24 as
the number of sstables. But the read latency is very low, my understanding
from the tableshistograms's sstable column is - it shows how many sstables
were read to complete the query. If so reading 24 sstables should take
sometime, at least maybe couple of seconds. Am I missing something here?
Does checking against index/bloom filters count towards sstable counter as
well?
