Hi All,

I'm using the SSTable with Size Tired Compaction Strategy with
10 days gc grace period as default.

And sstablemetadata command shows Estimated tombstone drop times
As follows after minor compaction on 9th Dec, 2018.

(excerpt)
Estimated tombstone drop times:%n
1510934467:      2475 * 2017.11.18
1510965112:       135
1510983500:       225
1511003962:       105
1511021113:      2280
1511037818:        30
1511055563:       120
1511075445:       165


I just think there are records that should be deleted on
18th Nov, 2018 in the SSTable by the output above. My understanding
is correct?

If my understanding I correct, could someone tell me why those
expired data remains after compation?




Regards,
Takashima
