Spark vs storm

This document compares the batch and streaming capabilities of Spark and Storm. Spark supports both batch and micro-batch processing while Storm supports micro-batch and real-time stream processing. Spark has been in production mode since 2013 and is implemented in Scala, while Storm has been used since 2011 and is implemented in Clojure and Java. Spark includes libraries for SQL, streaming, and machine learning while Storm uses spouts to read data streams and bolts to filter and join data in topologies. Both integrate with Hadoop and support fault tolerance, though Spark has improved reliability when used with YARN. Performance tests show Spark Streaming can process more records per second than Storm.

- 2. Batch vs Streaming Spark • Batch & micro-batch processing Storm • Micro-batch & real-time stream processing Batch Streaming
- 3. Usability Spark Storm Production mode Since 2013 (UC Berkeley) Since 2011 (Twitter) Implemented in Scala (In-memory processing) Clojure API Language Java, Scala, Python Java, Scala, Clojure, others Library components SparkSQL Spark Streaming MLLib (Machine Learning) GraphX (graph) Stream Spouts (read data stream) Bolts (filters, joins) Topologies
- 4. Hadoop compatibility Spark Storm Data sources HDFS, Hbase, Cassandra HDFS, Hbase, Kafka Ressource Manager YARN, Mesos Mesos Latency Few seconds < 1 second Fault tolerance (every record processed) Exactly once At least once Reliability Improved reliability (Spark + YARN) Guarantees no data loss (Storm + Kafka)
- 5. Supported distribution N/A Manual configuration needed Supported
- 6. Performance • This is NOT an official benchmark in term of performance of Spark and Storm System Performance Storm (Twitter) 10,000 records/s/node Spark Streaming 400,000 records/s/node Apache S4 7,000 records/s/node Other Commericial Systems 100,000 records/s/node http://www.cs.duke.edu/~kmoses/cps516/dstream.html
