How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe E2E workflow now builds controller, operator, and exporter-set-controller images with CI-specific Make targets. Image caches include the relevant ChangesCI image build flow
Estimated code review effort: 2 (Simple) | ~10 minutes Mergeability Score: 🟡 Moderate · up to The workflow may reuse an image built with an outdated Go toolchain when only the repository Go version changes, potentially producing incorrect or inconsistent e2e images. The cache keys should include .go-version before merge; the remaining duplicate-build issue is limited to CI efficiency. Possibly related PRs

86-86: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winRemove non-CI Containerfiles from these cache keys.
The changed CI targets build from
Containerfile.prebuilt. The keys also hashcontroller/Containerfile,controller/Containerfile.operator, andcontroller/Containerfile.exporter-set-controller, which these targets do not read. Changes to those files cause unnecessary image rebuilds.Keep each key limited to files consumed by its target.

controller/MakefileLines 147-153 also compile and containerizeexporter-set-controller, but this job saves only the controller image. The exporter-set-controller job invokes the standalone target at Lines 173-176. When both caches miss, the workflow builds the exporter-set-controller image twice.Add a target that builds only the controller image and use it here. Keep

Switch the e2e workflow's controller, operator, and exporterset-controller build jobs from multi-stage docker-build (pulls ~1.5GB go-toolset image) to the CI-optimized path that compiles on the runner with cached Go modules and packages into minimal ubi-micro containers. Add docker-build-exporter-set-controller-ci as a standalone target so the e2e workflow can build the ESC image independently (docker-build-ci builds controller + ESC together, but e2e needs them in separate parallel jobs). Update cache keys to include Containerfile.prebuilt. Signed-off-by: Benny Zlotnik <bzlotnik@redhat.com>
