Upgrade Notes

This is a major release that brings many things to the table.

Configuration

No configuration changes are needed.

Deployment

Because of the reporting schema update, it is recommended to:

Make sure you have upgraded to 0.7.10 before and that it was fully deployed.
Test the upgrade on a staging or dev environment.
Starting from 0.7.0 Karafka Web UI supports rolling deploys, so there is no need to "stop the world".
The Web UI interface may throw 500 errors during the upgrade because of schema incompatibility (until Puma is deployed). This will have no long-term effects and can be ignored.
Karafka::Web::Errors::Processing::IncompatibleSchemaError is expected. It is part of the Karafka Web UI zero-downtime deployment strategy. This error allows the Web UI materialization consumer to back off and wait for it to be replaced with a new one.
Perform a rolling deployment (or a regular one) and replace all consumer processes.
Update the Web UI Puma.
No CLI command execution is required. Starting from this release (0.8.0), the Karafka Web UI contains an automatic schema migrator that allows it to automatically adjust internal topic data formats.
Enjoy.

0.7.10 (2023-10-31)

[Fix] Max LSO chart does not work as expected (#201)

0.7.9 (2023-10-25)

[Enhancement] Allow for Karafka::Web.producer reconfiguration from the default (Karafka.producer).
[Change] Rely on karafka-core >= 2.2.4 to support lazy loaded custom web producer.

0.7.8 (2023-10-24)

[Enhancement] Support transactional producer usage with Web UI.
[Fix] Prevent a scenario where an ongoing transactional producer would have stats emitted and an error that could not have been dispatched because of the transaction, creating a dead-lock.
[Fix] Make sure that the recent displays the most recent non-compacted, non-system message.
[Fix] Improve the recent message display to compensate for aborted transactions.
[Fix] Fix ReferenceError: response is not defined that occurs when Web UI returns refresh non 200.

0.7.7 (2023-10-20)

[Fix] Remove thor as a CLI engine due to breaking changes.

0.7.6 (2023-10-10)

[Fix] Fix nested SASL/SAML data visible in the routing details (#173)

0.7.5 (2023-09-29)

Upgrade Notes

NO rolling upgrade needed. Just configuration update.

If you are using ui.visibility_filter this option is now ui.visibility.filter (yes, only . difference).
If you are using a custom visibility filter, it requires now two extra methods: #download? and #export?. The default visibility filter allows both actions unless message is encrypted.
ui.show_internal_topics config option has been moved and renamed to ui.visibility.internal_topics.

0.7.4 (2023-09-19)

[Improvement] Skip aggregations on older schemas during upgrades. This only skips process-reports (that are going to be rolled) on the 5s window in case of an upgrade that should not be a rolling one anyhow. This simplifies the operations and minimizes the risk on breaking upgrades.
[Fix] Fix not working ps for macOS.

0.7.3 (2023-09-18)

[Improvement] Mitigate a case where a race-condition during upgrade would crash data.

0.7.2 (2023-09-18)

[Improvement] Display hidden by accident errors for OSS metrics.

Upgrade Notes

This is a major release that brings many things to the table.

Configuration

Karafka Web UI now relies on Roda session management. Please configure the ui.sessions.secret key with a secret value string of at least 64 characters:

# Configure it BEFORE enabling
Karafka::Web.setup do |config|
  # REPLACE THIS with your own value. You can use `SecureRandom.hex(64)` to generate it
  # You may want to set it per ENV
  config.ui.sessions.secret = 'REPLACE ME! b94b2215cc66371f2c34b7d0c0df1a010f83ca45 REPLACE ME!'
end

Karafka::Web.enable!

Deployment

Because of the reporting schema update and new web-ui topics introduction, it is recommended to:

Make sure you have upgraded to 0.6.3 before and that it was deployed. To all the environments you want to migrate to 0.7.0.
Upgrade the codebase based on the below details.
Stop the consumer materializing Web-UI. Unless you are running a Web-UI dedicated consumer as recommended here, you will have to stop all the consumers. This is crucial because of schema changes. karafka-web 0.7.0 introduces the detection of schema changes, so this step should not be needed in the future.
Run a migration command: bundle exec karafka-web migrate that will create missing states and missing topics. You need to run it for each of the environments where you use Karafka Web UI.
Deploy all the Karafka consumer processes (karafka server).
Deploy the Web update to your web server and check that everything is OK by visiting the status page.

Please note that if you decide to use the updated Web UI with not updated consumers, you may hit a 500 error, or offset-related data may not be displayed correctly.

Code and API changes

bundle exec karafka-web install is now a single-purpose command that should run only when installing the Web-UI for the first time.
For creating needed topics and states per environment and during upgrades, please use the newly introduced non-destructive bundle exec karafka-web migrate. It will assess changes required and will apply only those.
Is no longerui.decrypt has been replaced with ui.visibility_filter API. This API by default also does not decrypt data. To change this behavior, please implement your visibility filter as presented in our documentation.
Karafka Web UI 0.7.0 introduces an in-memory topics cache for some views. This means that rapid topics changes (repartitions/new topics) may be visible up to 5 minutes after those changes.
ui.decrypt setting has been replaced with ui.visibility_filter API. This API by default also does not decrypt data. To change this behavior, please implement your visibility filter as presented in our documentation.
Karafka Web-UI 0.7.0 introduces an in-memory topics cache for some views. This means that rapid topics changes (repartitions/new topics) may be visible up to 5 minutes after those changes.
Karafka Web UI requires now a new topic called karafka_consumers_metrics. If you use strict topic creation and ACL policies, please make sure it exists and that Karafka can both read and write to it.

[Fix] Remove files from 0.7.0 accidentally added to the release.

0.6.2 (2023-07-22)

[Fix] Do not recommend running a server as a way to bootstrap the initial state.
[Fix] Ensure in the report contract, that karafka-core, karafka-web, rdkafka and librdkafka are validated.

[Feature] Introduce producers errors tracking.
[Improvement] Display the error origin as a badge to align with consumers view topic assignments.
[Improvement] Collect more job metrics for future usage.

[Improvement] Use estimated errors count for counters presentation taken from the errors topic instead of materialization via consumers states to allow for producers errors tracking.
[Improvement] Introduce schema_version to error reports.
[Improvement] Do not display the dispatched error message offset in the breadcrumb and title as it was confused with the error message content.
[Improvement] Display error_class value wrapped with code tag.
[Improvement] Display error type value wrapped with label tag.

Upgrade Notes

Because of the reporting schema update, it is recommended to:

First, deploy all the Karafka consumer processes (karafka server)
Deploy the Web update to your web server.

Please note that if you decide to use the updated Web UI with not updated consumers, you may hit a 500 error or offset related data may not be displayed correctly.

Disabling producers instrumentation

Producers error tracking is enabled by default. If you want to opt out of it, you need to disable the producers' instrumentation by clearing the producers' listeners:

Karafka::Web.setup do |config|
  # Do not instrument producers with web-ui listeners
  config.tracking.producers.listeners = []
end

Custom producers instrumentation

By default, Karafka Web-UI instruments only Karafka.producer. If you use producers initialized by yourself, you need to connect the listeners to them manually. To do so, run the following code:

::Karafka::Web.config.tracking.producers.listeners.each do |listener|
  MY_CUSTOM_PRODUCER.monitor.subscribe(listener)
end

Please make sure not to do it for the default Karafka.producer because it is instrumented out of the box.
