config - configuration for initializing JedisPool

storeMapper - mapper containing which datatype, storing value's key that Bolt uses

RedisStoreBolt

public RedisStoreBolt(JedisClusterConfig config,
 RedisStoreMapper storeMapper)

Constructor for Redis Cluster environment (JedisCluster).

Parameters:

config - configuration for initializing JedisCluster

storeMapper - mapper containing which datatype, storing value's key that Bolt uses

Method Details

process

public void process(Tuple input)

Process a single non-tick tuple of input. Implementation needs to handle ack manually. More details on IBolt.execute(Tuple).

Specified by:

process in class BaseTickTupleAwareRichBolt

Parameters:

input - The input tuple to be processed.

declareOutputFields
