If you don't need a value, you don't have to store anything. You can

Remember about the standard Cassandra's column overhead which is, as far as
I remember, 15 bytes, so it's 45 bytes in total - 50% more than you
estimated, which kind of m
Hello Mark and thanks for you reply.
1) i store is as UTF8String.All digits are from 0x30 to 0x39 and should
take 1 byte each digit. Since all characters are digits it should have 15
bytes.
2) I will change the data i am storing to decrease the usage , in value i
will find some small value to store
What are you storing these 15 chars as; string, int, double, etc.? 15 chars
does not translate to 15 bytes.
You may be mixing up replication factor and quorum when you say "Cassandra
cluster has 3 servers, and data is stored in quorum ( 2 servers )." You
read and write at quorum (N/2)+1 where N=to
I have column family with 2 raws.
2 raws have overall 100 million columns.
Each columns have name of 15 chars ( digits ) and same 15 chars in value (
also digits ).
Each column should have 30 bytes.
Therefore all data should contain approximately 3GB.
Cassandra cluster has 3 servers , and data is s
