Could Apache Spark become a universal computation engine?
Spark Summit keynotes are known for their surprises, and this year the stand-out changes were in data streaming, with sub-millisecond times predicted for some workloads. With multiple avenues open for potential success, the community is watching as Spark matures to fulfill the promise of what it could be: But does that promise include becoming a database?
Exploring the gap between theoretical possibilities and reality, Matthew Hunt (pictured) technologist at Bloomberg LP, discussed the maturation of Spark with George Gilbert (@ggilbert41) and David Goad (@davidgoad), co-hosts of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during this year’s Spark Summit event in San Francisco, California.
As a pioneer of streaming media, Bloomberg has a long history developing apps for news and finance and has developed its own relational database, ComDB2. “Everyone needs a database,” Hunt said, adding that most companies do not have the resources to develop their own. This leads to the question: Can Spark become a database?
Hunt believes that Spark has the promise to become a Universal Computation Engine. Describing a universal system as having distributed file store, database with transactional semantics, extensible analytics and the ability to stream data in, he asked, “how close can you come to that?”
Maturity means real-world use
Although the dream might be a universal system, the more practical question is how to make Spark and other databases work well together.
“If you have to master 5,000 skills and 200 different products, that’s a huge impediment for real-world usage,” said Hunt, who sees practical usage coalescing around a smaller set of options.
Hunt predicted that Apache Arrow, which powers columnar in-memory analytics, is about to explode because “it lets you connect these systems radically more efficiently in a standardized way.”
