It is SSTable counts in each level.

SSTables in each level: [40/4, 442/10, 97, 967, 7691, 0, 0, 0]
So you have 40 SSTables in L0, 442 in L1, 97 in L2 and so forth.
'40/4' and '442/10' have numbers after slash, those are expected maximum number of
SSTables in that level and only displayed when you have more than that threshold.

Hi –



Can someone explain the meaning for the levelled compaction in cfstats –



SSTables in each level: [40/4, 442/10, 97, 967, 7691, 0, 0, 0]



SSTables in each level: [61/4, 9, 92, 945, 8146, 0, 0, 0]



SSTables in each level: [34/4, 1000/10, 100, 953, 8184, 0, 0, 0





Thanks,

Kanwar
