What is Apache Kafka?
Kafka 4.4 hardens share groups and Streams, then 4.3.2 patches two data-loss risks a day later
Kafka 4.4.0 landed on October 22 with 25 KIPs and 963 commits: dead-letter queues for share groups, transactional state stores for Streams, broker-side custom task assignors, and detection of misrouted client connections. A day later 4.3.2 fixed around 60 issues, most notably two potential data-loss bugs in tiered storage size-based retention and time index truncation. 4.2.2 followed the same bugfix pattern in September.
What is Rivet?
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.
Apache Kafka vs Rivet: editorial side-by-side
Apache Kafka
5.0DEVOPS
Kafka 4.4 hardens share groups and Streams, then 4.3.2 patches two data-loss risks a day later
◆ Current state
Kafka 4.4.0 landed on October 22 with 25 KIPs and 963 commits: dead-letter queues for share groups, transactional state stores for Streams, broker-side custom task assignors, and detection of misrouted client connections. A day later 4.3.2 fixed around 60 issues, most notably two potential data-loss bugs in tiered storage size-based retention and time index truncation. 4.2.2 followed the same bugfix pattern in September.
◆ Where it's heading
Share groups are moving from a working queue model toward operational completeness, with dead-letter handling and offset initialization from a file. Streams is getting the same treatment through broker-side assignment and transactional stores, and deprecations such as broker.id and the 5.0 removal notice show cleanup ahead of the next major. Older branches continue to take bugfix releases.
◆ Prediction
Bugfix releases on 4.4 and 4.3 are the near-term next step. The deprecations marked for removal in 5.0 suggest that major is being prepared, though the entries give no date.
Rivet
7.5DEVOPS
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
◆ Current state
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.
◆ Where it's heading
Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.
◆ Prediction
Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.
