[jira] [Comment Edited] (BEAM-2931) Apex support for portable side input

    [ https://issues.apache.org/jira/browse/BEAM-2931?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16211806#comment-16211806 ]

-----------------------------------------------------------

https://github.com/apache/beam/pull/4011 migrated to using a multimap as the materialization format for side inputs.

The migration used a trivial multimap -> iterable -> multimap conversion within the Apex runner for first pass implementation purposes. Note that this is no different then the current materialization from a performance perspective it just moves this logic within the purview of the runner. Consider improving the internal materialization format from this trivial and unoptimal mapping.
