Spark Join, the brand new skinny consumer abstraction for Spark
Apache Spark — the information analytics engine for large-scale knowledge, now downloaded over 45 million occasions a month — is the place Databricks started.
Seven years in the past, after we first began Databricks, we thought it could be out of the realm of chance to run Spark on cell… We had been incorrect. We didn’t know this is able to be attainable. With Spark Join, this might turn out to be a actuality.
Reynold Xin (Co-founder and Chief Architect)
Spark is usually related to large knowledge facilities and clusters, however knowledge apps don’t stay in simply large knowledge facilities anymore. They stay in interactive environments like notebooks and IDEs, net functions, and even edge units like Raspberry Pis and iPhones. Nevertheless, you don’t usually see Spark in these locations. That’s as a result of Spark’s monolith driver makes it exhausting to embed Spark in distant environments. As an alternative, builders are embedding functions in Spark, resulting in points with reminiscence, dependencies, safety, and extra.
To enhance this expertise, Databricks launched Spark Join, which Reynold Xin referred to as “the biggest change to [Spark] for the reason that undertaking’s inception”.
With Spark Join, customers will have the ability to entry Spark from any machine. The consumer and server at the moment are decoupled in Spark, permitting builders to embed Spark into any utility and expose it by means of a skinny consumer. This consumer is programming language–agnostic, works even on units with low computational energy, and improves stability and connectivity.
