Release 5.3

Patch notes

This section contains all patch notes for Kadeck 5.3.x.

Release 5.3.2 (Hotfix)

Fixed infinite scanning when searching across partitions with exactly one record.
Fixed "Change Codec" button not clickable on Kadeck Desktop.

Release 5.3.1 (Hotfix Desktop)

Fixed n-th window issue on Kadeck Desktop.

Release 5.3.0 

We're excited to announce the release of Kadeck 5.3.0, bringing essential updates to our platform:
  1. Auth/OpenID Authentication Integration: Use OAuth and OpenID to authenticate your user.
  2. Easy Group Mapping for LDAP & OpenID: Instead of matching Kadeck group names with those in your directory service, you can now specify which external group name to map each Kadeck group to. This optional feature supports both LDAP and OpenID. By default, group mapping will still rely on name matching.
  3. Security Hotfix: Addresses the CVE-2023-34054 vulnerability.

Release 5.2

We’re excited to launch Kadeck 5.2, packed with major updates to our data protection policies, data catalog, and core architecture. This version enhances our Data Protection Policies and adds supports for Apple Silicon and ARM for both Kadeck Desktop and Kadeck Teams. Please read our Kadeck 5.2 release blog post to learn more about the new features.

Release 5.2.3 (Hotfix)

Fixed a problem caused by incomplete topic monitoring data.
Fixed wrong offset calculation for partitions with 0 records.
Fixed wrong total record count.

Data Catalog: Export, import, and create topic buttons moved to the header for smaller screens.‍

Release 5.2.1

Fixed profile links with special characters in the data browser.
Fixed issue where topics with a single record were not being scanned.
Fixed JavaScript runtime memory leaks.
Fixed desktop download architecture detection: If you are running release 5.2.0 on Apple Silicon, please download mac-arm.zip instead of mac.zip through the UI.

Release 5.2.0

Introducing Apple Silicon & ARM support for Kadeck Desktop and Kadeck Teams.
Improved Kafka data streaming client and fixed offset calculation that was wrong in certain scenarios and prevented Kadeck from loading all records.
Schema Registry - dependent Protobuf codecs no longer get initialized without a configured Schema Registry
Fixed inclusion of codecs with negative priority in auto detection.
Data Policies: Added support for JSON paths as data protection fields (e.g., "accountid.string" will only affect "string" fields inside "accountid"). 
Data Policies: Specify groups that should be excluded from a data policy.
Data Catalog: Improves backwards compatibility for owner assignments in Data Catalog.

Release 5.1

Warning
Activating the new monitoring section can lead to slightly higher memory and thread consumption. A new right is required to access the monitoring section. Learn more

Kadeck 5.1 brings a brand new Alert Notifications section to Kadeck. This way you will be informed about problems in your Kafka system and can fix them before others are affected. Receive notifications in your favorite tools such as Slack, Microsoft Teams, Pagerduty or via email.

The AI-based Health Assistant has been enhanced and is now smarter than ever. Improve the availability and reliability of your Kafka system with intelligent support from Kadeck.

Security is an important component: whether for companies with 5 users or 800+ users, with version 5.1. we take Kadeck security to a new level. This is our commitment as a partner to the largest banks, critical infrastructure and logistics companies that depend on security without compromise.

Unfortunately, some bugs have crept into the gigantic Kadeck 5 release, which have now also been fixed with Kadeck 5.1.
We look forward to your feedback and hope you enjoy the new features!

Release 5

Find out all about our new intelligent Kafka ops platform here: Kadeck - Intelligent Kafka Ops.
As a team, there is nothing more exciting than releasing something truly new and revolutionary.
Kadeck 5.0 revolutionizes Apache Kafka Monitoring in many ways and raises the bar in the industry even higher: Kadeck 5 comes with a groundbreaking new Kafka Monitoring section and the industry's first AI-based Health Assistant. This release is all about the Kafka infrastructure.
We, the team behind Kadeck, hope that you have as much fun with the new version as we had while working on it.

AI-Powered Kafka Health Assistant

Kadeck 5.0 introduces a groundbreaking AI-powered Kafka Health Assistant. Whether you are new to Kafka or an experienced pro, the AI Assistant will help keep your Kafka infrastructure operating smoothly 24 x 7. It continuously assesses the health of your Kafka clusters, topics, consumers, and partitions and automatically recommends changes that will improve performance and avoid downtime.

Kafka monitoring section

Kadeck 5.0 also introduces a Kafka monitoring module. The Kafka monitoring module contains three new dashboards: Monitoring Overview, Broker monitoring and Topic monitoring that visualize real-time and historic Kafka key performance metrics such as:
  1. I/O
  2. Throughput
  3. Storage
  4. Replicas
  5. Consumer group status
  6. Partition and leader skew
  7. And many more
The Kafka Monitoring module is the perfect complement to Kadeck. It makes Kadeck the industry’s most complete Kafka performance solution, allowing you to not only monitor, but also analyze and troubleshoot Kafka performance quickly and confidently from a single platform.

Consumer Monitoring Enhancements

Kadeck contains many features for analyzing and reconfiguring Kafka consumers and consumer groups. Kadeck 5.0 introduces a new ability to view consumers and consumer lag grouped by topic. In this view, the total lag of all consumer groups is aggregated for each topic, which makes it easy to see whether certain topics are experiencing lag problems.
The new Healt
h Assistant monitors your consumer groups and notifies you, if, for example, a consumer group is not consuming from all partitions of a topic which can lead to data loss.
Kafka Connect auto-restart
To make it easier for infrastructure and operations teams to ensure higher uptime, the new Health Assistant can monitor and restart crashed Kafka Connect tasks. This helps ensure data streaming continuity 24x7 with less manual oversight.

Other Kadeck Enhancements

  1. Navigate records in the data browser using the arrow keys
  2. Topic details view no longer closes if you click a record twice
  3. Protobuf Codec improvements
  4. Table shows total items now
  5. Security improvements
  6. The consumer rights are now more fine-granular. Read our article about the new consumer right management.
  7. The drop-down list box in the data browser has been replaced with the Maximum Results drop-down list box and no longer limits the number of records scanned, but the actual records returned. This has an impact when a search or filter is applied.
