Hi Rahul, If you are expecting 15 GB of data per day, here is the calculation. 1 Day = 15 GB, 1 Month = 450 GB, 1 Year = 5.4 TB, so your raw data size for one year is 5.4 TB with replication factor of 3 it would be around 16.2 TB of data for one year. Taking compaction into consideration and you

Hi All, We are planning to set up a cluster of 5 nodes with RF 3 for write heavy project, our current database size is around 500 GB. And it is growing at rate of 15 GB every day. We learnt that cassandra consumes space for compaction processes, So how can we calculate the amount of disk space we
