Work Description: mxm opened a new pull request #12062:
URL: https://github.com/apache/beam/pull/12062
When the state cache is enabled in the Python SDK, the batch mode of the
Flink
Runner currently only allows a single user state cell because a new cache
token
is generated for each state cell; the caching code in the Python SDK Harness
only supports one cache token per user state handler.
Theoretically multiple cache tokens would work but would just be adding to
the
payload. We should make sure to just send a single cache token in batch
mode (which is already the case in streaming)
