What is Skipper?

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.

Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

What is Thanos?

Thanos is rebuilding Receive around multi-tenancy, and shipping it through a stuttering RC train.

Thanos is working through the 0.42.0 release candidates, where the headline work is on Receive: tenant lifecycle handling, per-endpoint configuration, and fanout information surfaced in Thanos Query. The line also adopted Go's *os.Root API, which rc.2 exists mainly to clean up after. The release pipeline itself has been unreliable — rc.0 was skipped outright because base image SHA updates broke it, so rc.1 and rc.2 carry identical feature notes.

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.

◆ Current state

Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

◆ Where it's heading

The Redis L2 integration suggests the Skipper team is addressing the multi-replica cache coherence problem that large deployments encounter. If this pattern continues, distributed-state options—persistent rate limiting, distributed circuit breakers using the same Redis client abstraction—are the natural follow-ons. The high patch cadence signals active production deployment rather than feature-driven development.

◆ Prediction

The Redis client abstraction introduced in v0.27.92 will be extended to other stateful filters, particularly rate limiting, given that distributed rate limiting is the most common request for API gateways running at multi-replica scale.

Thanos is rebuilding Receive around multi-tenancy, and shipping it through a stuttering RC train.

◆ Current state

Thanos is working through the 0.42.0 release candidates, where the headline work is on Receive: tenant lifecycle handling, per-endpoint configuration, and fanout information surfaced in Thanos Query. The line also adopted Go's *os.Root API, which rc.2 exists mainly to clean up after. The release pipeline itself has been unreliable — rc.0 was skipped outright because base image SHA updates broke it, so rc.1 and rc.2 carry identical feature notes.

◆ Where it's heading

The centre of gravity is multi-tenant operation. Per-endpoint configuration and tenant lifecycle handling are what an operator needs to run one Thanos install for many teams rather than one per team, and the Query fanout view is the observability that makes such a topology debuggable. The parallel fixes to multi-tier query setups — preserving external label matchers across Query A → Query B → Sidecar chains — point at the same reality: deployments are getting deeper, not just wider.

◆ Prediction

A 0.42.0 stable should follow once the *os.Root regressions settle. The RC notes are cumulative and the feed is quiet since June, so treat cadence here as release-train artefact rather than a slowdown in the project.
