[GitHub] [kafka] dengziming commented on pull request #12109: KAFKA-13863: Prevent null config value when create topic in KRaft mode
dengziming commented on PR #12109: URL: https://github.com/apache/kafka/pull/12109#issuecomment-1118264999 @cmccabe, Yeah, it's unnecessary to change `ReplicationControlManager`, however, there is still a difference, in KRaft mode, the null config value is treated as removing configs, so creating topics with null config value will just act the same with creating topics without that config value. Do you think this is a reasonable change? or this is an incompatible bug? -- This is an automated message from the Apache Git Service.

[GitHub] [kafka] konL opened a new pull request, #12124: rename isDone to hasComplete
konL opened a new pull request, #12124: URL: https://github.com/apache/kafka/pull/12124 I used deep learning to discover that the method 'isDone' changed in 4af50bb8600c37ee2e3597fba9a54a29cef94afa. The code snippet before and after the change is as follows. ``` public boolean isDone() { return isDone; } ``` ``` public boolean isDone() { return result.get() != INCOMPLETE_SENTINEL; } ``` We thought we could rename `isDone` to `hasComplete` with a more specific meaning. We are actually looking at analysing the reasons for renaming identifiers and we would like to get advice from more experienced people, so would appreciate your feedback from one of the following perspectives. 1. `(merge)`you accept this renaming opportunity and agree with the recommended name 2. `(agree and not recommend)`you accept the renaming but disagree with the recommended name, do you think the recommended name means the same thing or is the recommended name simply not suitable? 3. `(not agree and useful)`Would our suggested renaming opportunity be useful for your other refactoring activities? 4. `(not agree and not fix) `You do not think our suggested renaming opportunity is appropriate. Is this because you think the identifier meaning does not need to be renamed or is it some other issue? We look forward to your feedback!

[jira] [Created] (KAFKA-13876) Mirrormaker-2 consumer settings not working
Christian Bates created KAFKA-13876: --- Summary: Mirrormaker-2 consumer settings not working Key: KAFKA-13876 URL: https://issues.apache.org/jira/browse/KAFKA-13876 Project: Kafka Issue Type: Bug Components: mirrormaker Affects Versions: 2.6.1, 2.5.0 Reporter: Christian Bates I am starting a mirrormaker connect cluster using ./bin/connect-mirror-maker.sh and a properties file. I followed the guide at https://github.com/apache/kafka/tree/trunk/connect/mirror to attempt to configure the consumer properties, however, no matter what I set, the timeout for the consumer remains fixed at the default, confirmed both by kafka outputting its config in the log and by timing how long between disconnect messages I get. e.g. I set: {{CLOUD_EU.consumer.request.timeout.ms=12}} In the properties that I start MM-2 with and it is ignored. based on various guides I have found while looking at this, I have also tried {{CLOUD_EU.request.timeout.ms=12}} {{CLOUD_EU.cluster.consumer.request.timeout.ms=12}} {{CLOUD_EU.consumer.override.request.timeout.ms=12}} {{CLOUD_EU.cluster.consumer.override.request.timeout.ms=12}} None of which have worked. How can I change the consumer request.timeout setting? Context: I am attempting to use mirrormaker 2 to replicate data between AWS Managed Kafkas (MSK) in 2 different AWS regions - one in eu-west-1 (CLOUD_EU) and the other in us-west-2 (CLOUD_NA), both running Kafka 2.6.1. For testing I am currently trying just to replicate topics 1 way, from EU -> NA. This works fine for topics with small messages on them, but one of my topic has binary messages up to 20MB in size. When I try to replicate that topic I get an error every 30 seconds {{[2022-04-21 13:47:05,268] INFO [Consumer clientId=consumer-29, groupId=null] Error sending fetch request (sessionId=INVALID, epoch=INITIAL) to node 2: {}.

For testing I am currently trying just to replicate topics 1 way, from EU -> NA. This works fine for topics with small messages on them, but one of my topic has binary messages up to 20MB in size. When I try to replicate that topic I get an error every 30 seconds {{[2022-04-21 13:47:05,268] INFO [Consumer clientId=consumer-29, groupId=null] Error sending fetch request (sessionId=INVALID, epoch=INITIAL) to node 2: {}.

mumrah commented on PR #12050: URL: https://github.com/apache/kafka/pull/12050#issuecomment-1118712139 @dengziming @cmccabe I've updated this PR with the changes from #12072. I've also modified the bootstrap mechanism to use a file with the KRaft snapshot format rather than a property in meta.properties. This is a slight departure from the KIP, but using a snapshot will open up the ability for us to bootstrap other records on first startup. If we agree that this is a good approach, I can update the KIP and discussion thread. -- This is an automated message from the Apache Git Service.

Converting DefaultStreamPartitioner to the new built-in partitioner is a bit tricky since kstreams calls the partitioner explicitly and then passes in the partition during send.

[jira] [Commented] (KAFKA-8769) Consider computing stream time independently per key
[ https://issues.apache.org/jira/browse/KAFKA-8769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17532427#comment-17532427 ] Matthias J. Sax commented on KAFKA-8769: Just a "random" comment, based on some other discussion I just had: if we do track stream time per key, it could be an issue if a key "goes away" – stream-time for this key would stop to advance, and thus we could not close the corresponding window (for windowed aggregations and left/outer stream-stream join). > Consider computing stream time independently per key > > > Key: KAFKA-8769 > URL: https://issues.apache.org/jira/browse/KAFKA-8769 > Project: Kafka > Issue Type: Improvement > Components: streams >Reporter: John Roesler >Priority: Major > Labels: needs-discussion, needs-kip > > Currently, Streams uses a concept of "stream time", which is computed as the > highest timestamp observed by stateful operators, per partition. This concept > of time backs grace period, retention time, and suppression. > For use cases in which data is produced to topics in roughly chronological > order (as in db change capture), this reckoning is fine. > Some use cases have a different pattern, though. For example, in IOT > applications, it's common for sensors to save up quite a bit of data and then > dump it all at once into the topic. See > https://stackoverflow.com/questions/57082923/kafka-windowed-stream-make-grace-and-suppress-key-aware > for a concrete example of the use case. > I have heard of cases where each sensor dumps 24 hours' worth of data at a > time into the topic. This results in a pattern in which, when reading a > single partition, the operators observe a lot of consecutive records for one > key that increase in timestamp for 24 hours, then a bunch of consecutive > records for another key that are also increasing in timestamp over the same > 24 hour period. With our current stream-time definition, this means that the > partition's stream time increases while reading the first key's data, but > then stays paused while reading the second key's data, since the second batch > of records all have timestamps in the "past". > E.g: > {noformat} > A@t0 (stream time: 0) > A@t1 (stream time: 1) > A@t2 (stream time: 2) > A@t3 (stream time: 3) > B@t0 (stream time: 3) > B@t1 (stream time: 3) > B@t2 (stream time: 3) > B@t3 (stream time: 3) > {noformat} > This pattern results in an unfortunate compromise in which folks are required > to set the grace period to the max expected time skew, for example 24 hours, > or Streams will just drop the second key's data (since it is late). But, this > means that if they want to use Suppression for "final results", they have to > wait 24 hours for the result. > This tradeoff is not strictly necessary, though, because each key represents > a logically independent sequence of events. Tracking by partition is simply > convenient, but typically not logically meaningful. That is, the partitions > are just physically independent sequences of events, so it's convenient to > track stream time at this granularity. It would be just as correct, and more > useful for IOT-like use cases, to track time independently for each key. > However, before considering this change, we need to solve the > testing/low-traffic problem. This is the opposite issue, where a partition > doesn't get enough traffic to advance stream time and results remain "stuck" > in the suppression buffers. We can provide some mechanism to force the > advancement of time across all partitions, for use in testing when you want > to flush out all results, or in production when some topic is low volume. We > shouldn't consider tracking time _more_ granularly until this problem is > solved, since it would just make the low-traffic problem worse. -- This message was sent by Atlassian Jira (v8.20.7#820007)

[jira] [Created] (KAFKA-13879) Exponential backoff for reconnect does not work
Chern Yih Cheah created KAFKA-13879: --- Summary: Exponential backoff for reconnect does not work Key: KAFKA-13879 URL: https://issues.apache.org/jira/browse/KAFKA-13879 Project: Kafka Issue Type: Bug Components: network Affects Versions: 2.7.0 Reporter: Chern Yih Cheah When a client connects to a SSL listener using PLAINTEXT security protocol, after the TCP connection is setup, the client considers the channel setup is complete (in reality the channel setup is not complete yet). The client issues API version request after that. When issuing API version request, reconnection exponential backoff is reset. Since the broker expects SSL handshake, client's API version request will cause the connection to disconnect. Reconnect will happen without exponential backoff since it has been reset.

[jira] [Created] (KAFKA-13880) DefaultStreamPartitioner may get "stuck" to one partition for unkeyed messages
Artem Livshits created KAFKA-13880: -- Summary: DefaultStreamPartitioner may get "stuck" to one partition for unkeyed messages Key: KAFKA-13880 URL: https://issues.apache.org/jira/browse/KAFKA-13880 Project: Kafka Issue Type: Bug Components: streams Affects Versions: 2.4.0 Reporter: Artem Livshits While working on KIP-794, I noticed that DefaultStreamPartitioner does not call .onNewBatch. The "sticky" DefaultStreamPartitioner introduced as a result of https://issues.apache.org/jira/browse/KAFKA-8601 requires .onNewBatch call in order to switch to a new partitions for unkeyed messages, just calling .partition would return the same "sticky" partition chosen during the first call to .partition. The partition doesn't change even if the partition leader is unavailable. Ideally, for unkeyed messages the DefaultStreamPartitioner should take advantage of the new built-in partitioning logic introduced in [https://github.com/apache/kafka/pull/12049.] Perhaps, it could return null partition for unkeyed message, so that KafkaProducer could run built-in partitioning logic. -- This message was sent by Atlassian Jira (v8.20.7#820007)

We should use `TestUtils.waitForBrokersOutOfIsr` not `TestUtils.waitForBrokersInIsr` 2. `TestUtils.waitForBrokersInIsr` needs to send RPC but we can directly use MetadataCache which is in the memory, so it's faster and more reliable, maybe we can improve `TestUtils.waitForBrokersInIsr` in the future 3.
