public abstract class QueryConsistencyException
extends QueryExecutionException

A failure to reach the required consistency level during the execution of a query.

Such an exception is returned when the query has been tried by Cassandra but cannot be achieved with the requested consistency level because either:

• the coordinator did not receive enough replica responses within the rpc timeout set for Cassandra;
• some replicas replied with an error.
