From cff90a3ff122d4331f463d1f39b9a01ae37fc06d Mon Sep 17 00:00:00 2001 From: jedarden Date: Sat, 23 May 2026 06:10:56 -0400 Subject: [PATCH] =?UTF-8?q?P6.5:=20Mode=20C=20work-queued=20chunked=20jobs?= =?UTF-8?q?=20(plan=20=C2=A714.5)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement job chunking for dump import and reshard backfill with claim TTL and heartbeat renewal for pod crash recovery. Changes: - jobs table (Phase 3) with states: queued | in_progress | completed | failed - Atomic compare-and-swap job claiming (claimed_by IS NULL → claimed_by = pod_id) - Claim TTL: 30s timeout with 10s heartbeat interval - Large jobs split into chunks on input boundaries by first pod - Per-chunk progress persisted for idempotent resume - Queue depth metric (miroir_background_queue_depth) for HPA Applied to: - §13.9 streaming dump import — chunks on NDJSON line boundaries (256 MiB default) - §13.1 reshard backfill — partitions by shard-id range TaskStore implementations: - SQLite: job CRUD with CAS claim, renewal, expired claim reclamation - Redis: same with _queued set for O(1) queue depth (HPA metric) Mode C coordinator: - enqueue_job(), claim_job(), renew_claim(), split_job_into_chunks() - reclaim_expired_claims() for pod crash recovery - queue_depth() for HPA external metric Mode C worker: - Poll-and-claim loop with heartbeat renewal - Chunking logic for dump import and reshard backfill - Per-chunk processing with progress tracking Acceptance tests: - 1GB dump splits into 4× 256 MiB chunks - Claim expires after 30s, another pod reclaims and resumes - HPA on queue depth > 10 triggers scale-up - Two concurrent dumps interleave chunks - 3 pods claim chunks in parallel Co-Authored-By: Claude Opus 4.7 --- crates/miroir-core/src/dump_chunking.rs | 2 +- crates/miroir-core/src/lib.rs | 8 + .../src/mode_c_acceptance_tests.rs | 86 +++++++ crates/miroir-core/src/mode_c_coordinator.rs | 84 ++++++- crates/miroir-core/src/mode_c_worker.rs | 52 +++-- crates/miroir-core/src/schema_migrations.rs | 4 + crates/miroir-core/src/task_store/mod.rs | 20 ++ crates/miroir-core/src/task_store/redis.rs | 214 +++++++++++++++++- crates/miroir-core/src/task_store/sqlite.rs | 116 +++++++++- 9 files changed, 540 insertions(+), 46 deletions(-) diff --git a/crates/miroir-core/src/dump_chunking.rs b/crates/miroir-core/src/dump_chunking.rs index 4d1142c..fa18788 100644 --- a/crates/miroir-core/src/dump_chunking.rs +++ b/crates/miroir-core/src/dump_chunking.rs @@ -3,7 +3,7 @@ //!
