feroz shaik commented on CASSANDRA-15263:
-----------------------------------------
I figured out that the app deletes using : "DELETE FROM \"sal_purge\" USING
TIMESTAMP ? WHERE key=? AND column1=?;"; is actually causing range bound
tombstones. I used sstabledump to know that.
"rows" : [
{
"type" : "range_tombstone_bound",
"start" : {
"type" : "inclusive",
"clustering" : [
"15e0088cdb99f399290e531a452e4c2c32d547a852607cb2819ff8fbd565ed53", "*" ],
"deletion_info" : \{ "marked_deleted" : "2019-09-27T06:20:16.033334Z",
"local_delete_time" : "2019-09-27T06:38:02Z" }
}
},
But other problems i have is that the sstabledump is erroring out with below
which may be another problem.bug itself:

My main point of concern now is that I cannot reproduce the error on my lab by
cqlsh driver with CL-all.
[~benedict] - since we know this is for sure a bug , when can we expect any
fix/patch for this? Kindly let us know.

> The below errors continued in the log file as long as the process was up.

> The nodetool version says 3.11.4 and the no of connections on native por t-
