sjvanrossum opened a new pull request, #39830:
URL: https://github.com/apache/beam/pull/39830
Use `Consumer.position(TopicPartition)` and
`Consumer.currentLag(TopicPartition)` to update the latest offset in
`PartitionState`.
This change reuses local metadata from recently completed record fetches
instead of periodically requesting the broker for end offsets.
This PR is a follow up to #39285 with additional changes to reduce
synchronization overhead in `consumerPollLoop` to a minimum since
`PartitionState` will likely be updated more frequently than the offset
consumer interval.
