Work Description: lostluck opened a new pull request #6948: [BEAM-4124]
datamgr.go:Remove chunksize constraint
URL: https://github.com/apache/beam/pull/6948
Go SDK harness was limited to elements of at most ~4MB with this check, but
provided no means to increase it. The chunking is valuable for batching tiny
elements over RPCs to improve throughput but is less meaningful for larger
elements.
The Go SDK shouldn't be dictating maximum element size, and let that be
configurable by the FnAPI transport (eg. GRPC) to the runner harness instead.
This should have an implicit ~2-4GB cap on element size.
