Work Description: bsidhom opened a new pull request #5688: [BEAM-4285]
Implement Flink batch side input handler
URL: https://github.com/apache/beam/pull/5688
This implements a state request handler for batch side inputs in the
portable Flink runner. The core implementation is the same as in the
non-portable runner: PCollections used as side inputs are materialized as
(in-memory) broadcast variables. These materialized elements are then exposed
by a side input state handler.
Note that we construct a duplicate `ExecutableProcessBundleDescriptor` here
rather than use an `ExecutableStage`. This is because the latter exposes side
input details (most importantly coder structure) that are not available in
`ExecutableStage`. It would be cleaner to migrate side input utilities from
executable bundle descriptors directly to `ExecutableStage`, but that refactor
should be done in a separate change.
