Flink Jira Bot updated FLINK-4399:
----------------------------------
Labels: auto-deprioritized-major flip-6 stale-minor (was:
auto-deprioritized-major flip-6)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is
still Minor, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Add support for oversized messages

> Key: FLINK-4399
> URL: https://issues.apache.org/jira/browse/FLINK-4399
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Environment: FLIP-6 feature branch
> Reporter: Stephan Ewen
> Priority: Minor
> Labels: auto-deprioritized-major, flip-6, stale-minor
>
> Currently, messages larger than the maximum Akka Framesize cause an error
> when being transported. We should add a way to pass messages that are larger
> than the Framesize, as may happen for:
> - {{collect()}} calls that collect large data sets (via accumulators)
> - Job submissions and operator deployments where the functions closures are
> large (for example because it contains large pre-loaded data)
> - Function restore in cases where restored state is larger than
> checkpointed state (union state)
> I suggest to use the {{BlobManager}} to transfer large payload.
> - On the sender side, oversized messages are stored under a transient blob
> (which is deleted after first retrieval, or after a certain number of minutes)
> - The sender sends a "pointer to blob message" instead.
> - The receiver grabs the message from the blob upon receiving the pointer
> message
> The RPC Service should be optionally initializable with a "large message
> handler" which is internally the {{BlobManager}}.
