5 Things One Must Know About Spark

Spark stores its data in the form of RDDs and they’re nothing but in memory collection of the data which are distributed across the machines, however, there are limitations. The unique feature of spark is it stores data depending on the kind of infrastructure.

Streaming support

Event Processing

Used for processing real-time streaming data.

It uses the D-stream: A series of RDDs, to process the real-time data support.

5 Things One Must Know About Spark

Cyclic Data flows

1. All jobs in Spark comprise a series of operators and run on a set of data.

2. All the operators in a job are used to construct a DAG.

3. The DAG is optimized by rearranging and combining operators where its possible.

Support for data frames

Data frame features

  • Ability to scale from KBS to PBS.

  • Support for a wide array of data formats and storage systems.

  • Seemless integration with all big data tooling and infrastructure via spark.
