Subject [jira] [Updated] (BEAM-3124) Get flattens working with portability.
Date Tue, 31 Oct 2017 19:00:02 GMT

     [ https://issues.apache.org/jira/browse/BEAM-3124?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Daniel Oliveira updated BEAM-3124:
----------------------------------
    Description: Some adjustments need to be made to the way flattens are handled to the get
them working for portability. Ideally flattens should be present in the execution graphs,
there should be no DoFns with multiple inputs, and flattens should execute on either the system
runners or SDK runners when appropriate.  (was: Some adjustments need to be made to the way
flattens are handled to the get them working for portability. Currently flattens are removed
from execution and the PCollections received by the flatten are instead sent to the DoFns
that consume the flatten. Ideally flattens should actually present in the execution graphs
to avoid having DoFns with multiple inputs, and they should be able to execute on either the
system runners or SDK runners when appropriate.)
