Seven years in the past, once we first began Databricks, we thought it will be out of the realm of chance to run Spark on cellular… We had been fallacious. We didn’t know this may be potential. With Spark Join, this might turn out to be a actuality.
Reynold Xin (Co-founder and Chief Architect)
Spark is usually related to massive knowledge facilities and clusters, however knowledge apps don’t reside in simply massive knowledge facilities anymore. They reside 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 arduous to embed Spark in distant environments. As a substitute, 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 known as “the biggest change to [Spark] for the reason that mission’s inception”.
With Spark Join, customers will have the ability to entry Spark from any machine. The shopper and server are actually decoupled in Spark, permitting builders to embed Spark into any utility and expose it by means of a skinny shopper.
