Jean-Baptiste Onofré resolved BEAM-918. --------------------------------------- Resolution: Fixed Fix Version/s: 0.4.0-incubating > Let users set STORAGE_LEVEL via SparkPipelineOptions. > ----------------------------------------------------- > > Key: BEAM-918 > URL: https://issues.apache.org/jira/browse/BEAM-918 > Project: Beam > Issue Type: Improvement > Components: runner-spark > Reporter: Amit Sela > Assignee: Jean-Baptiste Onofré > Fix For: 0.4.0-incubating > > > Spark provides different "STORAGE_LEVEL"s for caching RDDs (disk, memory, > ser/de, etc.). > The runner decides on caching when necessary, for example when a RDD is > accessed repeatedly. > > For batch, we can let users set their preferred STORAGE_LEVEL via > SparkPipelineOptions. > Note: for streaming we force a "MEMORY_ONLY", since (among other things) the > runner heavily relies on stateful operations, and it's natural for streaming > to happen in memory. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
