v0.11.6

• [Feature] Provide ability to pause/resume all partitions of a topic at once across all consumer processes via the Health Overview page (Pro). Topic-level commands are broadcast to all processes, and each process applies the command to partitions it owns within the specified consumer group. This simplifies bulk operations compared to pausing/resuming individual partitions one by one.
• [Enhancement] Optimize partition command tracker to use index-based lookup instead of iterating over 10,000 partitions during rebalance events. The tracker now maintains a partition index for O(n) lookups where n is the number of partitions with pending commands.
• [Enhancement] Report group.instance.id (static membership ID) per subscription group in consumer reports. This enables identifying consumers using Kafka's static group membership feature. The ID is displayed in the per-consumer subscription view header and in Health Overview below each process ID, making it easy to find a process by its static membership ID. Consumer schema version bumped to 1.6.0.
• [Enhancement] Display min.insync.replicas alongside replication factor on the topic replication page with fault tolerance indicators (Pro). Shows specific warnings for different resilience issues: no redundancy (RF=1), zero fault tolerance (RF ≤ minISR), and low durability (minISR=1). Each warning includes impact details, environment-aware severity messaging, and recommended actions. Helps users identify misconfigured topics that would cause outages or data loss.
• [Enhancement] Add .options CSS class for table columns containing action buttons, providing consistent width: 1%; white-space: nowrap styling to prevent column width fluctuation.
• [Enhancement] Add commands topic presence status check for Pro users. Warns when the karafka_consumers_commands topic is missing, which is required for commanding features (pause, resume, trace).
• [Enhancement] Disable "Quiet All" and "Stop All" buttons when only swarm or embedded consumers are running (Pro). These commands only work on standalone consumer processes.
• [Enhancement] Use low-ack producer variant (acks: 0) for Web UI reporting. Since Web UI reporting serves analytical purposes, fire-and-forget semantics minimize latency and overhead while occasional message loss is acceptable. Falls back to the original producer for idempotent/transactional producers.
• [Refactor] Refactor Status model into a DSL-based architecture with individual check classes. Each status check is now a separate class in Karafka::Web::Ui::Models::Status::Checks that declares its dependencies using depends_on :check_name DSL. Shared state is managed through a Context class, and the Step struct has been extracted to its own file. This improves maintainability, testability, and makes it easier to add new status checks in the future.
• [Fix] Fix session keys to use strings instead of symbols for compatibility with Roda's session management.
• [Fix] Fix actions and selector alignment in explorer and errors views by wrapping col-span elements in proper grid container.
