Class CassandraIdempotentRepository

java.lang.Object
org.apache.camel.support.service.BaseService
org.apache.camel.support.service.ServiceSupport
org.apache.camel.processor.idempotent.cassandra.CassandraIdempotentRepository
All Implemented Interfaces:
AutoCloseable, org.apache.camel.Service, org.apache.camel.ShutdownableService, org.apache.camel.spi.IdempotentRepository, org.apache.camel.StatefulService, org.apache.camel.SuspendableService
Direct Known Subclasses:
NamedCassandraIdempotentRepository
public class CassandraIdempotentRepository extends org.apache.camel.support.service.ServiceSupport implements org.apache.camel.spi.IdempotentRepository
Implementation of IdempotentRepository using Cassandra table to store message ids. Advice: use LeveledCompaction for this table and tune read/write consistency levels. Warning: Cassandra is not the best tool for queuing use cases See http://www.datastax.com/dev/blog/cassandra-anti-patterns-queues-and-queue-like-datasets
