commit e072706 Author: José Armando García Sancio <jsancio@users.noreply.github.com> Date: Tue Aug 8 14:31:42 2023 -0700 KAFKA-15312; Force channel before atomic file move (apache#14162) On ext4 file systems we have seen snapshots with zero-length files. This is possible if the file is closed and moved before forcing the channel to write to disk.

New PR due to merge issue. Changes line 57 in the RangeQuery class file from: public static <K, V> RangeQuery<K, V> withRange(final K lower, final K upper) { return new RangeQuery<>(Optional.of(lower), Optional.of(upper)); } to public static <K, V> RangeQuery<K, V> withRange(final K lower, final K upper) { return new RangeQuery<>(Optional.ofNullable(lower), Optional.ofNullable(upper)); } Testing strategy: Since null values can now be entered in RangeQuerys in order to receive full scans, I changed the logic defining query starting at line 1085 in IQv2StoreIntegrationTest.java from: final RangeQuery<Integer, V> query; if (lower.isPresent() && upper.isPresent()) { query = RangeQuery.withRange(lower.get(), upper.get()); } else if (lower.isPresent()) { query = RangeQuery.withLowerBound(lower.get()); } else if (upper.isPresent()) { query = RangeQuery.withUpperBound(upper.get()); } else { query = RangeQuery.withNoBounds(); } to query = RangeQuery.withRange(lower.orElse(null), upper.orElse(null)); because different combinations of isPresent() in the bounds is no longer necessary.

Mainly, changes the `RemoteStorageManager` interface in order to return `CustomMetadata` and then ensures these custom metadata are stored, propagated, (de-)serialized correctly along with the standard metadata throughout the whole lifecycle. It introduces the `remote.log.metadata.custom.metadata.max.size` to limit the custom metadata size acceptable by the broker and stop uploading in case a piece of metadata exceeds this limit. On testing: 1. `RemoteLogManagerTest` checks the case when a piece of custom metadata is larger than the configured limit. 2. `RemoteLogSegmentMetadataTest` checks if `createWithUpdates` works correctly, including custom metadata. 3. `RemoteLogSegmentMetadataTransformTest`, `RemoteLogSegmentMetadataSnapshotTransformTest`, and `RemoteLogSegmentMetadataUpdateTransformTest` were added to test the corresponding class (de-)serialization, including custom metadata. 4. `FileBasedRemoteLogMetadataCacheTest` checks if custom metadata are being correctly saved and loaded to a file (indirectly, via `equals`). 5. `RemoteLogManagerConfigTest` checks if the configuration setting is handled correctly.

There are situations in which a stream thread might only have standby tasks that are recycled to active task after a rebalance. In such situations, the stream thread might be faster in checking active tasks in restoration then the state updater removing the standby task to recycle from the state updater. If that happens the stream thread changes to RUNNING although it should wait until the standby tasks are recycled to active tasks and restored.

If the topic active segment contains some messages and there are no new incoming messages, then the active segment gets rotated to passive segment after the configured log.roll.ms timeout. The logic to find the candidate segment in RemoteLogManager does not include the recently rotated passive segment as eligible to upload it to remote storage so the passive segment won't be removed even after if it breaches by retention time/size. (ie) Topic won't be empty after it becomes stale. Added unit test to cover the scenario which will fail without this patch.

It renames Coordinator to CoordinatorShard; It renames ReplicatedGroupCoordinator to GroupCoordinatorShard. I was never really happy with this name. The new name makes more sense to me; It removes TopicPartition from the GroupMetadataManager. It was only used in log messages. The log context already includes it so we don't have to log it again. It renames assignors to consumerGroupAssignors.

The change introduces the `SubscribedTopicDescriber` interface that can be used to retrieve topic metadata such as the number of partitions or the racks from within an assignor. We use an interface because it allows us to wrap internal data structures instead of having to copy them. It is more efficient.

Previously, the context was recreated in this case.

There are several situations where this is useful, such as logging, implementing metadata transactions, or handling broker registration records. In the case where the QC is inactive, and simply replaying records, it is easy to compute the exact record offset from the batch base offset and the record index. The active QC case is more difficult. Technically, when we submit records to the Raft layer, it can choose a batch base offset later than the one we expect, if someone else is also adding records. While the QC is the only entity submitting data records, control records may be added at any time. In the current implementation, these are really only used for leadership elections. However, this could change with the addition of quorum reconfiguration or similar features. Therefore, this PR allows the QC to tell the Raft layer that a record append should fail if it would have resulted in a batch base offset other than what was expected. This in turn will trigger a controller failover. In the future, if automatically added control records become more common, we may wish to have a more sophisticated system than this simple optimistic concurrency mechanism. But for now, this will allow us to rely on the offset as correct. In order that the active QC can learn what offset to start writing at, the PR also adds a new RaftClient#endOffset function. At the Raft level, this PR adds a new exception, UnexpectedBaseOffsetException. This gets thrown when we request a base offset that doesn't match the one the Raft layer would have given us. Although this exception should cause a failover, it should not be considered a fault. This complicated the exception handling a bit and motivated splitting more of it out into the new EventHandlerExceptionInfo class. This will also let us unit test things like slf4j log messages a bit better.

But this time, there might be fetch request coming from follower, and try to check if the replica is eligible to be added into ISR here. At this moment, NPE will be thrown. Although it's fine since this topic is already deleted, it'd be better to avoid it happen. Reviewers: Luke Chen <showuon@gmail.com> commit af1f50f Author: Matthias J.

Based on the integration test, this does not apply to KRaft mode. Adds a broker restart that fails without the corresponding KafkaConfig change. Reviewers: Justine Olshan <jolshan@confluent.io> commit 38781f9 Author: Justine Olshan <jolshan@confluent.io> Date: Mon Jul 24 13:08:57 2023 -0700 KAFKA-14920: Address timeouts and out of order sequences (apache#14033) When creating a verification state entry, we also store sequence and epoch. On subsequent requests, we will take the latest epoch seen and the earliest sequence seen. That way, if we try to append a sequence after the earliest seen sequence, we can block that and retry. This addresses potential OutOfOrderSequence loops caused by errors during verification (coordinator loading, timeouts, etc).
