Sushma A Devendrappa commented on CASSANDRA-14482:
--------------------------------------------------
Thanks for all the feedback!
[~aweisberg] we have seen similar results as [~jolynch], several usecases show
better results than LZ4 and Deflate, ZSTD has good speed for most usecases
given same compression ratio.
Current code changes does not affect any testing neither touches any other code
part of cassandra itself, apart from adding a new compression. So this should
be safe changes for any experimentation and also real usage in production.
Dictionary based compression is a very good feature of ZSTD, that can be
enabled and code changes for that can go in a separate patch in other upcoming
releases. Current patch gives a good start for introducing ZSTD as a
compression variant and later add more feature.
