In a multi-topic table, if one Kafka topic becomes inaccessible (e.g. deleted externally), all other topics ingestion also stops. Fix: catch permanent (non-transient) exceptions per-topic in fetchMultipleStreams(), log and record the failed topic name in _failedTopics, and continue fetching the remaining topics. The caller (PinotTableIdealStateBuilder) reads getFailedTopics() after the fetch and emits a PARTITION_GROUP_METADATA_FETCH_ERROR metric tagged with the topic name for each failure, so operators can detect the inaccessible topic. Healthy topics proceed normally through ensureAllPartitionsConsuming(). TransientConsumerException handling is unchanged — transient failures still return false to trigger a retry via the retry policy. `bugfix` -- This is an automated message from the Apache Git Service.
