Over the past year we've migrated several clusters from DSE to Apache
Cassandra. We've mostly done I place conversions node by node with no
downtime. DSE 4.8.X to Apache Cassandra 2.1.x

I have a cluster that is running 3.11.4 ( was upgraded a while back from
2.1.16 ). what I see is a steady rate of read repair which is about 10%
constantly on only this 1 table. Repairs have been run (actually several
times). The table does not have a lot of writes to it so after repair, or
this table was actually leveled compaction before, just changed it to size
tiered yesterday while researching this.

I've actually noticed this as well on a few clusters I deal with but after
upgrading Cassandra from 3.11 to 4 we also changed to use Java 11 shortly
after the cluster upgrade. After I moved to Java 11 I have not experienced
a problem.

time given the size of our infrastructure. Is it safe to assume that the issue exists in the combination of upgrades from 3.11.x to 4.0.x and running on JAVA 8 ? Did you happen to have created a ticket for this when you observed the issue ? Thanks vaibhavOn Wed, Aug 16, 2023 at 11:15 AM Patrick Lee
