I'm going to store a 7 bits value in Cassandra and looking for the most efficient data structure for that. Could you please suggest what can be the best and efficient data type to store 7 bits value in C*?
If the value is a numeric, whole number you could use TINYINT, which is meant for storing 8-bit (signed) integers.
Information on this and other data types supported by Apache Cassandra® can be found in this doc: https://cassandra.apache.org/doc/stable/cassandra/cql/types.html
