Confluent Platform 6.1.0 Release Notes
6.1.0 is a major release of Confluent Platform that provides you with Apache Kafka® 2.7.0, the latest stable version of Kafka.
The technical details of this release are summarized below.
For more information about the 6.1.0 release, check out the release blog
and the Streaming Audio podcast.
Asynchronous topic-partition replicas that normally sit outside of the in-sync replica
(“ISR”) list, also known as observers, can now automatically be promoted into the ISR if a partition
is under-replicated or if the partition falls below the topic’s configured “min.insync.replicas” setting.
To enable, in your topic’s replica placement JSON, set “version” to 2 and add a line for
“observerPromotionPolicy” set to either “under-replicated” or “under-min-isr”.
Self-Balancing Clusters in Confluent Platform 6.1 expands observability by adding an additional REST API callS to monitor
Self-Balancing tasks when adding a new broker.
Confluent Control Center
- ksqlDB “Add stream/table” buttons removed - These buttons previously led to a modal UI that
enabled users to visually create streams and tables. This UI has been eliminated in favor of
simply using SQL queries for stream and table creation.
- Some RBAC protected pages throughout the UI will experience a brief 404 error on page reload
before the page loads as expected. This is due to a delay in permission response and will be
fixed in a subsequent release.
- When configuring a connector through the UI, if a topic name and topic regex is specified an
error message may be sporadically displayed. As a workaround, we recommend resubmitting your
configuration changes. This will be fixed on a subsequent patch release.
