Redis Accelerates Spark by Over 100 Times

Mountain View, February 2, 2016—Redis, the home of Redis, today announced its integration with Spark SQL and the release of the Spark-Redis connector package. Redis’ benchmarks using time-series data show that running Spark on Redis as a data store results in 135 times faster processing compared to Spark using HDFS and 45 times faster processing compared to Spark using Tachyon as an off-heap data store or Spark storing the data on-heap. The Spark-Redis connector package is open source and provides a library for writing to and reading from a Redis cluster with access to all of Redis’ data structures – String, Hash, List, Set, Sorted Set, bitmaps, hyperloglogs – from Spark as RDDs. In addition, the package also ensures close cluster alignment between Spark and Redis clusters, reducing network overhead and ensuring optimal processing times. The main advantages of using Redis with Spark include:

“Big data is coming of age and customers are demanding that big data insights are extracted in real-time,” said Yiftach Shoolman, co-founder and CTO of Redis. “This is where Redis fills the gap by delivering both the right performance and optimized distributed memory infrastructure to accelerate Spark. Our goal is to make Redis the de-facto data store for any Spark deployment.”

The Spark-Redis solution enables:

Additional planned enhancements to the solution include using the combination of Spark and Redis for other popular use cases such as graph computation and machine learning.

“The Spark-Redis connector package was developed by Redis in close collaboration with Databricks”, says Patrick Wendell, vice president of engineering at Databricks. “Spark and Redis are a powerful combination enabling sophisticated analytics with a great deal of simplicity and speed.”

“Spark with Redis is a combination that we have been waiting for”, says Yuval Levav, VP, R&D of Cooladata. “The new Spark-Redis solution will allow us to deliver analytics in real-time and bring instant insights to our customers.”

“Apache Spark is becoming a default in-memory engine for high-performance data integration and analytics,” said Matt Aslett, research director, data platforms and analytics at 451 Research. “The combination of Redis and Spark should enable high-performance, real-time analytics with extremely large and variable datasets.”
