How to edit / change Consistency Level to Cassandra

Hi All,

Need help to change consistency and serialConsistency from default (LOCAL_QUORUM and LOCAL_SERIAL) both to LOCAL_ONE, how to do that?
I noticed that both are in config.go file? I want to expose them as Environment Variable so I can change the value without compiling the code, how to do that?

Many thanks

Is there any environment variable can be set in docker for Consistency, serial Consistency, or set to
NetworkTopologyStrategy ? Something like CASSANDRA_REPLICATION_FACTOR or NUM_HISTORY_SHARDS?

regards,
