Hi, We have seen a weird behaviour in cassandra 3.6. Once our node was went down more than 10 hrs. After that, we had ran Nodetool repair multiple times. But tombstone are not getting sync properly over the cluster. On day- today basis, on expiry of every grace period, deleted records start surfacing again in cassandra.
It seems Nodetool repair in not syncing tomebstone across cluster. FYI, we have 3 data centres now. Just want the help how to verify and debug this issue. Help will be appreciated. -- Regards, Atul Saroha *Lead Software Engineer | CAMS* M: +91 8447784271 Plot #362, ASF Center - Tower A, 1st Floor, Sec-18, Udyog Vihar Phase IV,Gurgaon, Haryana, India
