----------------------------------------
Summary: Thrift should expose a native existence check API
Key: CASSANDRA-4736
URL: https://issues.apache.org/jira/browse/CASSANDRA-4736
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: sankalp kohli
Priority: Minor
Currently Cassandra does not have an existence check API. Because of this, data
needs to be read and thats how you know whether data is present or not.
This is not optimal because one replica needs to provide data. Instead a new
API could be exposed where each replica only sends out hash of the data.
Repairs and other stuff can happen like a normal read call.
