Role: Reviewer-R1
LGTM (round 1).
Checks:
- Original test intent is preserved: TestCancelWhileScan still asserts cancellation completes within 1s after cancel().
- Change scope is test-only and minimal: only pkg/ttl/ttlworker/scan_integration_test.go is updated.
- Recurrence analysis is consistent with evidence from the reopened flaky issue/build logs: current recurrence is timeout/runtime pressure rather than statement-boundary correctness.
- No unnecessary timing-only precise repro is retained: this update simplifies the stress profile and keeps deterministic cancellation coverage without extra reproducer-only paths.
Validation:
- ./tools/check/failpoint-go-test.sh pkg/ttl/ttlworker -run '^TestCancelWhileScan$' -count=20 (pass)

Long mode doesn't affect the CI, so I don't think this change will be helpful.
There was a problem hiding this comment.
Good point. I removed the testflag.Long() branch so CI and local runs now execute the same loop count (rounds := 10), while keeping the original cancellation assertion and test intent unchanged.

In `@pkg/ttl/ttlworker/scan_integration_test.go`:
- Line 44: There's a typo: the identifier "tesflag" used in the condition
calling tesflag.Long() should be the imported package "testflag"; replace the
incorrect "tesflag" with "testflag" so the condition reads testflag.Long(),
matching the import and the other usage (e.g., the call at line using
testflag.Long()) to fix the compile error.

What problem does this PR solve?
Issue Number: ref #66982
Problem Summary:
TestCancelWhileScanstill times out in CI under resource pressure. The previous fix in #67285 addressed statement-boundary cancellation correctness, but this test still spent too much time in long-mode stress setup/execution and could exceed shard timeout.What changed and how does it work?
This PR keeps the same cancellation assertions and makes the stress path cheaper and more deterministic:
TestCancelWhileScaninstead of issuing 10k single-row inserts.10default,30in-long) instead of time-based loops.sleepCoprRequest=200ms) so each round still exercises cancellation while avoiding heavy table size/time requirements.This keeps the regression coverage focused on cancellation responsiveness while removing the long-tail runtime behavior that caused timeouts.
