Partition size in Cassandra?

[Jony Geek]

Hi,

How can i get partition size in Cassandra?

https://docs.datastax.com/en/cassandra/2.1/cassandra/planning/planPlanningPartitionSize.html

It would be easy if i get partition size to check my data-model correct or not?

Thanks

The nodetool tablehistograms command will give you a summary of partition sizes:

I am unaware of any API to get the size of a particular partition. Seems like a reasonable thing to ask for, although it might not be a cheap calculation to do in real-time.
