+# WAL Checkpoint Fix — db-write Thread CPU Plan
+
+## Problem
+
+Fresh profiling of the production server shows the `db-write` thread consuming **77% average CPU** (peaking at 100%) while `lws-main` sits at 0.3%.
+
+The `perf` callgraph confirms 100% of the hot symbols are SQLite **B-tree read operations** running on the `db-write` thread:
+
+| % CPU | Symbol | Role |
+|-------|--------|------|
+| 13.88 | `sqlite3BtreeTableMoveto` | B-tree seek |
+| 10.05 | `sqlite3VdbeExec` | VM execution |
+| 7.77 | `rep_movs_alternative` | kernel memcpy in pread |
+| 7.76 | `sqlite3GetVarint` | varint decode |
+| 6.66 | `pcache1Fetch` | page cache lookup |
+| 6.02 | `memcpy` | data copy |
+
+These are **read-path** functions, not write-path. The `event-worker` thread accumulated only 3 CPU ticks over 5 minutes, meaning very few events are actually being stored.
+
+## Root Cause
+
+SQLite WAL auto-checkpoint. By default SQLite triggers a checkpoint every 1000 WAL pages. The checkpoint is executed by the **next writer** — which is always the `db-write` thread since all writes are funnelled through it.
+
+A WAL checkpoint reads every dirty page from the WAL file and writes it back to the main database file. This involves B-tree traversals to locate pages, which explains the `BtreeTableMoveto` dominance.
+
+The current `db_open_worker_connection` in `src/db_ops.c` sets `PRAGMA journal_mode=WAL` and `busy_timeout=5000` but does **not** configure `wal_autocheckpoint`. SQLite's default of 1000 pages applies.
+
+In earlier profiling runs the same CPU burn appeared on `lws-main` at 55-67% — because that thread was doing the writes directly before the thread-pool refactoring. The work simply moved threads; the total cost is unchanged.
+
+## Implementation Plan
+
+### Step 1 — Disable auto-checkpoint on the write connection
+
+In `db_open_worker_connection` add:
+
+```c
+sqlite3_exec(db, "PRAGMA wal_autocheckpoint=0;", NULL, NULL, NULL);
+```
+
+This prevents the write thread from ever running a checkpoint inline with normal writes.
+
+### Step 2 — Add a periodic checkpoint job type to the thread pool
+
+Add a new job type `THREAD_POOL_JOB_WAL_CHECKPOINT` to `thread_pool.h`.
+
+The handler in `thread_pool.c` calls:
+
+```c
+sqlite3_wal_checkpoint_v2(db, NULL, SQLITE_CHECKPOINT_PASSIVE, NULL, NULL);
+```
+
+`PASSIVE` mode checkpoints only pages that are not currently being read, so it never blocks readers.
+
+### Step 3 — Submit the checkpoint job on a timer
+
+In the existing 60-second periodic timer in `websockets.c`, add a call to submit a WAL checkpoint job to the write queue:
+
+```c
+thread_pool_submit_wal_checkpoint();
+```
+
+This runs the checkpoint once per minute on the write thread, but as a **bounded, predictable** operation rather than being triggered unpredictably by every INSERT.
+
+### Step 4 — Also disable auto-checkpoint on reader connections
+
+In `db_open_worker_connection`, the same `wal_autocheckpoint=0` applies to reader connections too. Readers can also trigger checkpoints in SQLite; disabling it on all connections ensures only the explicit periodic job does checkpointing.
+
+### Step 5 — Run a TRUNCATE checkpoint at shutdown
+
+In `thread_pool_shutdown`, before closing the write connection, run:
+
+```c
+sqlite3_wal_checkpoint_v2(db, NULL, SQLITE_CHECKPOINT_TRUNCATE, NULL, NULL);
+```
+
+This ensures the WAL is fully flushed and truncated on clean shutdown, keeping the database file compact.
+
+## Files Changed
+
+| File | Change |
+|------|--------|
+| `src/db_ops.c` | Add `PRAGMA wal_autocheckpoint=0` in `db_open_worker_connection` |
+| `src/thread_pool.h` | Add `THREAD_POOL_JOB_WAL_CHECKPOINT` enum value |
+| `src/thread_pool.c` | Add `execute_wal_checkpoint_job` handler; add checkpoint-at-shutdown in `thread_pool_shutdown`; add `thread_pool_submit_wal_checkpoint` helper |
+| `src/websockets.c` | Call `thread_pool_submit_wal_checkpoint()` in the 60-second periodic timer |
+
+## Expected Impact
+
+- `db-write` CPU should drop from ~77% to near 0% when idle (no events to store)
+- Periodic checkpoint bursts of a few seconds every 60s instead of continuous burn
+- No change to data durability — WAL still protects against crashes; checkpoint just moves data from WAL to main DB file
+- Readers are unaffected — PASSIVE checkpoint never blocks them
+
+## Risk
+
+- If the relay crashes between checkpoints, the WAL file may be larger than before (up to 60s of accumulated writes). This is safe — SQLite replays the WAL on next open. The WAL file size is bounded by the write rate, which is low.
+- PASSIVE checkpoint may not checkpoint all pages if readers hold them. This is fine — the next checkpoint will catch up.
+
+## Verification
+
+After deploying, re-run the profiler:
+
+```bash
+./deploy_lt_debug.sh && DURATION=300 INTERVAL=5 ./tests/thread_cpu_profile.sh
+```
+
+Expected: `db-write` avg CPU drops below 5%.
