[jira] [Comment Edited] (BEAM-2930) Flink support for portable side
input
[ https://issues.apache.org/jira/browse/BEAM-2930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16211805#comment-16211805 ]

-----------------------------------------------------------
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 Flink 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.
