I plan on doing some more thorough testing, it’s just a matter of finding
time.

Thanks for testing this out Jon. Apart from the compression ratio could you
also test the insertion rate and GC? 14482 allows you to use full range of Zstd
compression levels.

Hey all,
I finally got around to doing some testing. Nothing too crazy, I had it
run on my laptop while I did other things around the house.
Test 1: Inserting Random Data in a K/V table, 10 million inserts
LZ4 compression rate: 0.909857609644112
ZStd: 0.6136099401596449
Test 2: Inserting fairl
Thanks all for your input. The consensus is to go forward with this ticket.

We have been using Zstd compressor across different products/services here
and have seen significant improvements, getting this in 4.0 would be a big
win.
+1

Thanks Ariel & Jonathan.
Michael, I have addressed the comments in the issue so we're using the latest
jar now. I've posted the updated patch in the latest comment of the ticket. In
addition there is a JMH performance benchmark in the C* repo
(CompressorPerformance) that tests various Compressor
Seems low risk, potentially high reward.
I can run some tests next week to get a rough idea of how compression
ratios differ as well as if there's a difference in performance.
I won't be testing correctness, just looking at the performance profile.

+0.5
I skimmed the jira and github diff and a few things came to mind:
- There are multiple comments about using an older jar than the latest
version.
- I did not see any performance test results to form an opinion on any
gains/caveats as a user. This was the first thing I looked for.
- I did not
Hi,
I am +1 since it's an additional compressor and not the default.

IMO "add a new compression class that has demonstrable benefits to Sushma
and Joseph" is sufficiently noninvasive that we should allow it into 4.0.

Hey folks,
Just wanted to get a pulse on whether we can proceed with ZStd support. The
consensus on the ticket was that it’s a very valuable addition without any risk
of destabilizing 4.0. It’s ready to go if there aren’t any objections.

Hi,
I am checking to see if we can include CASSANDRA-1448 in 4.0 release which
provides ZSTD compressor for Cassandra. Currently changes are under review,
implementation has unit test coverage similar to other compressors, also tested
in Instagram’s shadow clusters.
Implementation structure is
