[jira] [Updated] (BEAM-833) Exercise Dynamic Splitting in the DirectRunner

[Thomas Groh (JIRA)]

 [ 
https://issues.apache.org/jira/browse/BEAM-833?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
 ]

Thomas Groh updated BEAM-833:
-
Description: 
This primarily means calling the {{BoundedSource#splitAtFraction}} API during 
the evaluation of a BoundedReadEvaluatorFactory - this can return the work via 
addUnprocessedElements. 

At a later point, the {{MonitorRunnable}} within 
{{ExecutorServiceParallelExecutor}} can examine currently evaluating work and 
invoke a {{TransformExecutor#split}} method, which can return to the runner 
some amount of input, which can be scheduled to use more of the available 
threads.

Thomas Groh updated BEAM-833:
-
Description: (was: BoundedSource#splitIntoBundles and 
UnboundedSource#generateInitialSplits are the methods by which sources can be 
accessed in parallel. Exercising these methods allows reads (and all transforms 
downstream) to be executed in parallel both pre and post a GroupByKey)
