WRT the investigation we've been doing around a flink failure for large
settings:
In my own investigation into the problem on the google internal runner, the
"big" configuration ends up being too large for protocol buffer serialization,
with a single ~10GB StateResponse, causing the issue. Protos have a hard cap of
2GB in serialized size.
From #beam-go slack discussion, and other research, java and python also
fails with large configurations, as it's not yet implemented anywhere to page
through large side inputs.
`--input_options='{"num_records": 2000000, "key_size":100,
"value_size":900}' --access_percentage=1`
and
`--input_options='{"num_records": 10000000, "key_size":100,
"value_size":90}' --access_percentage=1`
work by cutting data total down to 1/5th.
This will affect all portable runners, but not any of the legacy ones,
because they don't pass data around through the protos. A JIRA is being filed
about it.
