NamedCassandraAggregationRepository 通过在 Cassandra 表中关联密钥存储交换，如下所示：
CAMEL_AGGREGATION.cql
CREATE TABLE CAMEL_AGGREGATION (
NAME varchar, -- Repository name
KEY varchar, -- Correlation id
EXCHANGE_ID varchar, -- Exchange id
EXCHANGE blob, -- Serialized exchange
PRIMARY KEY (NAME, KEY)
) WITH compaction = {'class':'LeveledCompactionStrategy'}
AND gc_grace_seconds = 86400;
另外，CassandraAggregationRepository 没有 NAME 列，并可扩展为使用其他数据模型。
