sjvanrossum opened a new issue, #33096:
URL: https://github.com/apache/beam/issues/33096
### What happened?
#31137 overwrites the per-split metric `backlog_bytes.${SPLIT}` with a
per-partition value rather than the accumulated value for the split. #31281
introduces a `Map` to store metrics for all past and current splits (1
partition) of the `ReadFromKafkaDoFn` instance and may repeatedly overwrite
non-current splits with stale values. The map used to store these values is not
thread-safe and may trigger a `ConcurrentModificationException` since `GetSize`
and other SDF methods may concurrently attempt to read and write the map.
Finally, the per-split caches kept by the instance are keyed on TopicPartition,
which is not unique among all splits since the split may override the bootstrap
server.
