Hi,
I'm using a fairly standard install of Cassandra 3.11 on FreeBSD
12, by default filesystem is compressed using LZ4 and Cassandra tables
are compressed using LZ4 as well.
I was wondering if anybody had data about this already (or else, I will
probably do some tests myself, eventually): would it be a nice idea to
disable Cassandra compression and rely only on ZFS one?
In principle I can see some pros:
1. it's done in kernel, might be slightly faster
2. can (probably) compress more data, as I see a 1.02 compression factor
on filesystem even if I have compressed data in tables already
3. in upcoming ZFS version I will be able to use Zstd compression
(probably before Cassandra 4.0 is gold)
4. (can inspect compression directly at filesystem level)
But on the other hand application-level compression could have its
advantages.
cheers,
