* feat(runtime): add weighted workload scheduler Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * feat(runtime): switch catio to GreptimeTeam fork with admission-wait metrics Use the GreptimeTeam/catio fork (pinned c20eafc) which adds ClassStats::total_admission_wait and ClassStats::admitted, recorded at each QUEUED -> ADMITTED transition. This exposes the scheduler's own admission delay (excluding Tokio queueing and poll execution), enabling admission-wait based fairness gates. Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * chore: bump catio to dynamic-config revision Bump the catio scheduler fork to 9f4b028 which adds Scheduler::set_weight and Scheduler::set_max_concurrent_polls for runtime configuration. Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * feat(perf): runtime-adjustable workload scheduler parameters Expose dynamic adjustment of the experimental workload scheduler at runtime: - common-runtime: set_workload_scheduler_weights and set_workload_scheduler_max_concurrent_polls, which forward to the catio scheduler's set_weight/set_max_concurrent_polls when the scheduler is enabled and reject zero values. - servers: /debug/workload_scheduler/weights and /debug/workload_scheduler/max_concurrent_polls POST handlers, so operators can rebalance query/write shares or admission concurrency without restarting the datanode. Both endpoints return 400 with a clear reason when the scheduler is disabled or the requested value is invalid. Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * feat(perf): add GET /debug/workload_scheduler status endpoint Returns the current weights (per class), max_concurrent_polls, active_polls and per-class counters (queued, tasks, wakes, polls, completed, cancelled, admitted, total_admission_wait) as JSON. When the scheduler is disabled, returns enabled=false with the other fields omitted, so operators can distinguish 'disabled' from an error. Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * chore: bump catio to time-accounting revision Bump the catio scheduler fork to 257ba56 which replaces admission-count accounting with real execution-time accounting (pass += exec_time / (weight * concurrency)), so CPU share follows the configured weights regardless of poll length. Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * chore: bump catio to lock-free sampling revision Bump the catio scheduler fork to efdc0a4 which adds an optional downsampled clock sampling mode (SchedulerBuilder::sample_every_polls, default off) with a lock-free per-class atomic counter, so the downsampled path costs one fetch_add per poll instead of a global mutex.
