ConstSpout -> IdBolt -> DevNullBolt This topology measures speed of messaging between spouts->bolt and bolt->bolt ConstSpout : Continuously emits a constant string IdBolt : clones and emits input tuples DevNullBolt : discards incoming tuples
This topo helps measure the messaging speed between a spout and a bolt.
This topo helps measure how fast a spout can produce data (so no bolts are attached) Spout generates a stream of a fixed string.
This topo helps measure speed of word count.
This topo helps measure speed of reading from Hdfs.
This topo helps measure speed of reading from Kafka and writing to Hdfs.
This topo helps measure speed of reading from Kafka Spout Reads from Kafka.
This topo helps measure speed of writing to Hdfs Spout generates fixed length random strings.
