Subject: Re: Increased Disk Usage After Upgrading From Cassandra 3.x.x to 4.1.3
ou began to use Cassandra with 3 version or have you already migrate
before from previous version ( 2.x) ?
To be honest, i would suggest to use the last release avalable, and to rebuild
and relaad a fresh new cluster with a very low num_token ( and 3 nodes :-)
May i ask you why only single
have one table in a keyspace that is occupying 84.1GB of disk space:
ls -l /var/lib/cassandra/data/keyspace1/table1
…
-rw-rw-r--. 1 x 84145170181 Mar 18 08:28 nb-163033-big-Data.db
…

changed other than the
keystore and truststore was num_tokens (default: 16):
num_tokens: 256
I also noticed the compression ratio on the largest table is not good:
0.566085855123187
