* KAFKA-10437: Implement new PAPI support for test-utils (#9396) Implements KIP-478 for the test-utils module: * adds mocks of the new ProcessorContext and StateStoreContext * adds tests that all stores and store builders are usable with the new mock * adds tests that the new Processor api is usable with the new mock * updates the demonstration Processor to the new api Reviewers: Guozhang Wang <[email protected]> * KAFKA-10494: Eager handling of sending old values (#9415) Nodes that are materialized should not forward requests to `enableSendingOldValues` to parent nodes, as they themselves can handle fulfilling this request. However, some instances of `KTableProcessorSupplier` were still forwarding requests to parent nodes, which was causing unnecessary materialization of table sources. The following instances of `KTableProcessorSupplier` have been updated to not forward `enableSendingOldValues` to parent nodes if they themselves are materialized and can handle sending old values downstream: * `KTableFilter` * `KTableMapValues` * `KTableTransformValues` Other instances of `KTableProcessorSupplier` have not be modified for reasons given below: * `KTableSuppressProcessorSupplier`: though it has a `storeName` field, it didn't seem right for this to handle sending old values itself. Its only job is to suppress output. * `KTableKTableAbstractJoin`: doesn't have a store name, i.e. it is never materialized, so can't handle the call itself. * `KTableKTableJoinMerger`: table-table joins already have materialized sources, which are sending old values. It would be an unnecessary performance hit to have this class do a lookup to retrieve the old value from its store. * `KTableReduce`: is always materialized and already handling the call without forwarding * `KTableAggregate`: is always materialized and already handling the call without forwarding Reviewer: Matthias J.

The old configurations are still allowed (ensuring backward compatibility), but warning messages are written to the log to suggest users change to `include` and `exclude`. This is part of KIP-629. Author: Xavier Léauté <[email protected]> Reviewer: Randall Hauch <[email protected]> * KAFKA-10521; Skip partition watch registration when `AlterIsr` is expected (#9353) Before `AlterIsr` which was introduced in KIP-497, the controller would register watches in Zookeeper for each reassigning partition so that it could be notified immediately when the ISR was expanded and the reassignment could be completed. This notification is not needed with the latest IBP when `AlterIsr` is enabled because the controller will execute all ISR changes itself. There is one subtle detail. If we are in the middle of a roll in order to bump the IBP, then it is possible for the controller to be on the latest IBP while some of the brokers are still on the older one. In this case, the brokers on the older IBP will not send `AlterIsr`, but we can still rely on the delayed notification through the `isr_notifications` path to complete reassignments. This seems like a reasonable tradeoff since it should be a short window before the roll is completed.

Calling removeFromList is not enough. Reviewers: Jason Gustafson <[email protected]> * KAFKA-10611: Merge log error to avoid double error (#9407) When using an error tracking system, two error log messages result into two different alerts. It's best to group the logs and have one error with all the information. For example when using with Sentry, this double line of log.error will create 2 different Issues. One can merge the issues but it will be simpler to have a single error log line.

This would cause older versioned clients to never receive list-offset results. Reviewers: Boyang Chen <[email protected]> * MINOR: more log4j entry on elect / resignation of coordinators (#9416) When a coordinator module is being elected / resigned, our log entry is usually associated with a background scheduler on loading / unloading entries and hence it is unclear at the exact time when the election or resignation happens, and we have to then compare with the KafkaAPI's log entry for leaderAndISR / StopReplica to infer the actual time. I think add a couple new log entries indicating the exact time when it happens is helpful.

That ProcessingContext is used by both RetryWithToleranceOperator.executeFailed() and execute(), so it's not enough to just synchronize executeFailed(). So make all public methods of RetryWithToleranceOperator synchronized so that RetryWithToleranceOperator is now threadsafe. Tested with the addition of a multithreaded test case that fails consistently if the methods are not properly synchronized.

Sophie Blee-Goldman <[email protected]>, Matthias J. Sax <[email protected]> * MINOR: remove explicit passing of AdminClient into StreamsPartitionAssignor (#9384) Currently, we pass multiple object reference (AdminClient,TaskManager, and a few more) into StreamsPartitionAssignor. Furthermore, we (miss)use TaskManager#mainConsumer() to get access to the main consumer (we need to do this, to avoid a cyclic dependency). This PR unifies how object references are passed into a single ReferenceContainer class to - not "miss use" the TaskManager as reference container - unify how object references are passes Note: we need to use a reference container to avoid cyclic dependencies, instead of using a config for each passed reference individually. Reviewers: John Roesler <[email protected]> * MINOR: Handle lastFetchedEpoch/divergingEpoch in FetchSession and DelayedFetch (#9434) In 2.7, we added lastFetchedEpoch to fetch requests and divergingEpoch to fetch responses.

(#9431) DistributedHerder goes to updateConfigsWithIncrementalCooperative() synchronized method and called configBackingStore.snapshot() which take a lock on internal object in KafkaConfigBackingStore class. Meanwhile KafkaConfigBackingStore in ConsumeCallback inside synchronized block on internal object gets SESSION_KEY record and calls updateListener.onSessionKeyUpdate() which take a lock on DistributedHerder. This results to a deadlock. To avoid this, updateListener with new session key should be called outside synchronized block as it's done, for example, for updateListener.onTaskConfigUpdate(updatedTasks).

This class will be used in protocols. This PR creates the class, modifies code to use the class in the message protocol and changes the code surrounding the existing messages/json that used the old UUID class. SimpleExampleMessage was used only for testing, so all usages of UUID have been switched to the new class. SubscriptionInfoData uses UUID for processId extensively. It also utilizes java.util.UUID implementation of Comparable so that UUIDs can be ordered. This functionality was not necessary for the UUIDs used for topic IDs converted to java.util.UUID on the boundary of SubscriptionInfoData. Sorting was used only for testing, though, so this still may be changed. Also added tests for the methods of the new UUID class. The existing SimpleExampleMessage tests should be sufficient for testing the new UUID class in message protocols.

In this scenario, we attempt to send FindCoordinator to `leastLoadedNode`, but since that is blocked due to `max.in.flight=1` as a result of the pending metadata response, we never unblock unless we poll. This PR ensures we poll in this case.

This gives users a powerful knob to tune the impact of fsync. When an append is accepted from the state machine, it is held in an accumulator (similar to the producer) until the configured linger time is exceeded. This allows the implementation to amortize fsync overhead at the expense of some write latency. The patch also improves our methodology for testing performance. Up to now, we have relied on the producer performance test, but it is difficult to simulate expected controller loads because producer performance is limited by other factors such as the number of producer clients and head-of-line blocking. Instead, this patch adds a workload generator which runs on the leader after election. Finally, this patch brings us nearer to the write semantics expected by the KIP-500 controller. It makes the following changes: - Introduce `RecordSerde<T>` interface which abstracts the underlying log implementation from `RaftClient`. The generic type is carried over to `RaftClient<T>` and is exposed through the read/write APIs. - `RaftClient.append` is changed to `RaftClient.scheduleAppend` and returns the last offset of the expected log append. - `RaftClient.scheduleAppend` accepts a list of records and ensures that the full set are included in a single batch. - Introduce `RaftClient.Listener` with a single `handleCommit` API which will eventually replace `RaftClient.read` in order to surface committed data to the controller state machine. Currently `handleCommit` is only used for records appended by the leader.

Latest consumer fails to consume from 0.10.0.1 brokers. Below system tests are failing kafkatest.tests.client.client_compatibility_features_test.ClientCompatibilityFeaturesTest kafkatest.tests.client.client_compatibility_produce_consume_test.ClientCompatibilityProduceConsumeTest Solution: Current default value for MaxNumOffsets is 0. because to this brokers are not returning offsets for v0 request. Set default value for MaxNumOffsets field to 1. This is similar to previous [approach] (https://github.com/apache/kafka/blob/2.6/clients/src/main/java/org/apache/kafka/common/requests/ListOffsetRequest.java#L204) 2. In some scenarios, latest consumer fails with below error when connecting to a Kafka cluster which consists of newer and older (<=2.0) Kafka brokers `org.apache.kafka.common.errors.UnsupportedVersionException: Attempted to write a non-default currentLeaderEpoch at version 3` Solution: After #8295, consumer can set non-default CurrentLeaderEpoch value for v3 and below requests. One solution is to make CurrentLeaderEpoch ignorable. Author: Manikumar Reddy <[email protected]> Reviewers: David Jacot <[email protected]> Closes #9540 from omkreddy/fix-listoffsets * KAFKA-10471 Mark broker crash during log loading as unclean shutdown (#9364) LogManager writes a clean shutdown file when the broker shuts down. The presence of this file indicates that the broker had a clean shutdown and log recovery is not needed upon the next boot up. Earlier, LogManager would check for this file at the start of log loading workflow, and delete it after the log has been loaded. If the broker were to crash while loading logs, the file would not be deleted and mislead LogManager when it tries to load logs upon next boot up. Hence, a crash during log loading will not be considered a hard reset of broker. As part of this fix, we delete the clean shutdown file as soon as we look it up, at the start of log loading workflow. Thereafter, we maintain a boolean flag to indicate if broker underwent clean shutdown or not. So, if the broker were to crash while logs are being loaded, LogManager will be able to detect this as a hard reset. Reviewers: Jun Rao <[email protected]> * KAFKA-10632; Raft client should push all committed data to state machines (#9482) In #9418, we add a listener to the `RaftClient` interface. In that patch, we used it only to send commit notifications for writes from the leader. In this PR, we extend the `handleCommit` API to accept all committed data and we remove the pull-based `read` API. Additionally, we add two new callbacks to the listener interface in order to notify the state machine when the raft client has claimed or resigned leadership. Finally, this patch allows the `RaftClient` to support multiple listeners. This is necessary for KIP-500 because we will have one listener for the controller role and one for the broker role.

Author: Nitesh Mor <[email protected]> Reviewers: Manikumar Reddy <[email protected]> Closes #9556 from niteshmor/trunk * KAFKA-10661; Add new resigned state for graceful shutdown/initialization (#9531) When initializing the raft state machine after shutting down as a leader, we were previously entering the "unattached" state, which means we have no leader and no voted candidate. This was a bug because it allowed a reinitialized leader to cast a vote for a candidate in the same epoch that it was already the leader of. This patch fixes the problem by introducing a new "resigned" state which allows us to retain the leader state so that we cannot change our vote and we will not accept additional appends. This patch also revamps the shutdown logic to make use of the new "resigned" state. Previously we had a separate path in `KafkaRaftClient.poll` for the shutdown logic which resulted in some duplication. Instead now we incorporate shutdown behavior into each state's respective logic. Finally, this patch changes the shutdown logic so that `EndQuorumEpoch` is only sent by resigning leaders. Previously we allowed this request to be sent by candidates as well.

This caused a lot of allocation and GC activity when creating and closing the streams. It also does not buffer the reads or writes. This causes inefficiency when DefaultRecord.writeTo() does a series of small single bytes reads using various ByteUtils methods. The JNI is more efficient if the writes of uncompressed data were flushed in large pieces rather than for each byte. This is due to the the expense of context switching between the Java code and the native code. This is also the case when reading as well. Per luben/zstd-jni#141 the maintainer of zstd-jni and I agreed to not buffer reads and writes in favor of having the caller do that, so here we are updating the caller. In this patch, I upgraded to the most recent zstd-jni version with the buffer reuse built-in. This was done in luben/zstd-jni#143 and luben/zstd-jni#146 Since we decided not to add additional buffering of input/output with zstd-jni, I added the BufferedInputStream and BufferedOutputStream to CompressionType.ZSTD just like we currently do for CompressionType.GZIP which also is inefficient for single byte reads and writes. I used the same buffer sizes as that existing implementation. NOTE: if so desired we could pass a wrapped BufferSupplier into the Zstd*Stream classes to have Kafka decide how the buffer recycling occurs. This functionality was added in the latter PR linked above. I am holding off on this since based on jmh benchmarking the performance gains were not clear and personally I don't know if it worth the complexity of trying to hack around the reflection at this point in time. The zstd-jni uses a very similar default recycler as snappy does currently which seems to provide decent efficiency. While this PR fixes the defect, I feel that using BufferSupplier in both zstd-jni and snappy is outside of the scope of this bugfix and should be considered a separate improvement. I would prefer this change get merged in on its own since the performance gains here are very significant relative to the more incremental and minor optimizations which could be achieved by doing that separate work.
