Hello lampahome, Data will be compressed but you will also have to account for the replication factor that you will be using.

If I use var a as primary key and var b as second key, and a and b are 16 bytes and 8 bytes. And other data are 32 bytes. In one row, I have a+b+data = 16+8+32 = 56 bytes. If I have 100,000 rows to store in cassandra, will it occupy space 56x100000 bytes in my disk? Or data will be compressed? thx
