Hi,
we've seen G1GC going OOM on production clusters (repeatedly) with a 16GB
heap when the workload is intense, and given you're running on m4.2xl I
wouldn't go over 16GB for the heap.
I'd suggest to revert back to CMS, using a 16GB heap and up to 6GB of new
gen. You can use 5 as MaxTenuringThre

You may have better luck switching to G1GC and using a much larger
heap (16 to 30GB). 4GB is likely too small for your amount of data,
especially if you have a lot of sstables. Then try increasing
file_cache_size_in_mb further.
Cheers,

Hi,
I am trying to generate a random value of certain length and use that as one
of the value in CQL3. Below is an example
INSERT INTO "KS"."CF" (key, column1, value) VALUES
(613462303431313435313838306530667c6263317431756331, 2633174317563312f6f36,
blobAsUuid(timeuuidAsBlob(now())) + 1000);

Check out the 'cassandra-3.10' tag and follow the README instructions in
the redhat/ directory.

Hi,
Can you please let me know where I can get Cassandra 3.10 RPM? If its not
available, instruction to build it would be helpful.

Continuing to grasp at straws...
Is it possible that indexing is modifying the read path such that the
tablestats/tablehistograms output is no longer trustworthy? I notice more
realistic "local read count" numbers on tables which do not utilize SASI.
Would greatly appreciate any thoughts,
Thanks
Sounds like you want full auditing of CQL in the cluster. I have not seen
anything built into the open source version for that (but I could be missing
something). DataStax Enterprise does have an auditing feature.

Hi,
could you share your GC settings ? G1 or CMS ? Heap size, etc...
Thanks,

Further info - tablehistograms reports zeros for all percentiles for Read
Latency; tablestats also reports really low numbers for Bloom filter usage
(3-4 KiB, depending on node, whereas I'd expect orders of magnitude more
given other - less accessed - tables in this keyspace). This is the most
