Hi Amit,
That's some brilliant tests you have done there. It shows that the compaction
throughput not only can be a bottleneck on the speed of insert operations, but
it can also stress the JVM garbage collector. As a resu
es for too long. With
lower throughput large system can ingest more data. Does it make sense ?
Thanks,
Amit

Hi
ficial for workloads where
data is not kept/left on nodes for too long. With lower throughput large system
can ingest more data. Does it make sense ?

Amit, welcome and thank you for contributing the results from your test and
opening this discussion.
I don’t think anyone is arguing that the database shouldn’t take advantage of
available hardware.

Hi Amit,
I am inclined to agree with Bowen Song, in that benchmarks from an initially
empty cluster tend to lean more heavily on memtable and commit log bottlenecks
than a real-world long running cluster does, as the algorithmic

Do you think multi-threading is good to have now ? else please suggest
if I need to test further.

From my past experience, the bottleneck for insert heavy workload is
likely to be compaction, not commit log. You initially may see commit
log as the bottleneck when the table size is relatively small, but as
the table size increases, compaction will likely take its place and
become the new bot
