I was checking expected pricing of datastax astra using calculator but i am not able to understand what should i given in write size and read size parameter values.
Could you please guide how can i find those values from my existing cluster is there any metrics which i should check or any other method available in opscenter graphs?
There are some metrics around read requests available in OpsCenter:
For writes however there are no OpsCenter metrics around the size, but you could get an estimate on the max size by summing the data types for the table in question:
https://docs.datastax.com/en/cql-oss/3.1/cql/cql_reference/cql_data_types_c.html
You'll really need to get that info from the application though, that's the only real way to see what you are Inserting to know the size.
You can use a combination of the nodetool tablestats and nodetool tablehistograms outputs in order to get an estimate.
You can get the average partition size from the tablestats output while the tablehistograms output will give you the partition sizes read/written in the last 15 minutes.
If you need assistance, feel free to click on the Chat with an Expert button on the Astra DB pricing page. Cheers!
