Amit Sela updated BEAM-647: --------------------------- Summary: Faul-tolerant sideInputs via Broadcast variables.t (was: Faul-tolerant sideInputs via Broadcast variables.) > Faul-tolerant sideInputs via Broadcast variables.t > -------------------------------------------------- > > Key: BEAM-647 > URL: https://issues.apache.org/jira/browse/BEAM-647 > Project: Beam > Issue Type: Bug > Components: runner-spark > Reporter: Amit Sela > Assignee: Amit Sela > > Following https://github.com/apache/incubator-beam/pull/909 which enables > checkpointing to recover from failures, sideInputs (being implemented by > broadcast variables) should be handled in a specific manner as described > here: > http://spark.apache.org/docs/1.6.2/streaming-programming-guide.html#accumulators-and-broadcast-variables. > This is a bit more complicated than Aggregators (via Accumulators) as they > are implemented using a single "aggregating" Accumulator, while a pipeline > may contain multiple sideInputs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
