I encountered a problem.I use janusgraph configuration file to set the read consistency level, but I find that it does not take effect.
A warning is issued in the log, and through openManagement, the current execution level is QUORUM.I try to use mgmt.set("storage.cql.read-consistency-level","TWO”)，but all instances take effect.
How can I achieve read consistency level of TWO and only the current instance takes effect?
