<p>try <code>germnetwork.com</code> in the search view. the <code>d:</code> lookup finds subdomains like <code>tessa.germnetwork.com</code>, which was one of the reasons for building this index in the first place. the lists are prepared ahead of time; at request time we merge them and hydrate at most 50 candidates.</p><p>updates were where keeping the replica got awkward. say someone's display name changes from Alex to Ari. we need to remove the prefixes for the name <strong>currently in our search index</strong>. a newer row in another database can tell us “Ari” and lose the information needed to remove “Alex”. reading the old value from the overlay, then the snapshot, gives us the representation we're actually replacing.</p><p>Turso is still the durable store. the ingester consumes the relay's <code>subscribeRepos</code> firehose and sends batches through the Worker into Turso. search projects changes into the overlay every five minutes. request-indexing can also push a row directly into the overlay after writing it, so someone explicitly asking to be indexed doesn't have to wait for that pass.</p><p>heavypad runs the builds through Prefect. it exports Turso, builds the SQLite index with Zig, and uploads it to R2. the search machine checks the new artifact before attaching it. September 4's build took about 67 minutes; a late build leaves the previous one serving. identity and profile enrichment run on heavypad too.</p><h2>the remaining coupling</h2><p>i'd left a fallback in the Worker that tried Turso's full-text search when the engine found nothing. it was meant to cover replica lag. the replica was gone, but the fallback was still there.</p><p>under the race traffic, those queries saturated Turso and interfered with ingest writes. the backlog overflowed and events were dropped. turning the fallback off fixed that, until a search-machine restart triggered another fallback for an unreachable engine. that one is off now too. during a restart, uncached requests can get an empty answer for a few seconds.</p><p>request counters still write to Turso, so there is more to separate here. and the events we dropped need partial recovery through enrichment and PLC discovery. the <a href="https://tangled.org/zzstoatzz.io/typeahead/blob/main/docs/retros/2026-09-03-ingester-panic-hang-and-turso-saturation.md">incident report</a> has the timeline, including a separate 22-hour ingest hang caused by an unbounded telemetry flush.</p><h2>what i'm paying to keep</h2><p>the served artifact is now 14GB. removing the replica let us replace the search machine's 100GB volume with a 60GB one. ingest runs on one shared CPU, 256MB, with no volume. batch compute happens at home.</p><p>my May estimate was too optimistic about the serving bill staying flat as the corpus grew. index size and the memory needed to keep frequently used pages cached still grow. but this is a much more manageable setup, and i'm happy to have real traffic to measure it against.</p><p>i also made <a href="https://sites.wisp.place/zzstoatzz.io/race38/">the race to 38</a>, a live tracker for the vote. its “watch your votes” picker uses the same endpoint. the original bsky38 voting site is what drove the burst above.</p><p><a href="https://typeahead.waow.tech/stats">typeahead's stats</a> · <a href="https://typeahead.waow.tech/docs">API docs</a> · <a href="https://tangled.org/zzstoatzz.io/typeahead">source</a></p><footer class="page-footer"><p>Draft for editing · Data collected September 5, 2026.</p></footer></main><script>(() => { // docs/blog-assets/typeahead-sequel/traffic-evidence.json var traffic_evidence_default = { query: "SELECT date_bin(INTERVAL '15 minutes', start_timestamp) AS window, count(*) AS searches, percentile_cont(0.5) WITHIN GROUP (ORDER BY duration)*1000 AS p50_ms, percentile_cont(0.95) WITHIN GROUP (ORDER BY duration)*1000 AS p95_ms FROM records WHERE span_name='search' AND kind='span' GROUP BY 1 ORDER BY 1", min_timestamp: "2026-09-04T16:45:00Z", max_timestamp: "2026-09-04T19:00:00Z", data: [ { window: "2026-09-04T16:45:00Z", searches: 163, p50_ms: 4.023614812500001, p95_ms: 17.986704 }, { window: "2026-09-04T17:00:00Z", searches: 100, p50_ms: 2.9867675, p95_ms: 20.027130500000002 }, { window: "2026-09-04T17:15:00Z", searches: 124, p50_ms: 4.007566291666667, p95_ms: 17.8079115 }, { window: "2026-09-04T17:30:00Z", searches: 1705, p50_ms: 3.5615873028074874, p95_ms: 16.620122741735535 }, { window: "2026-09-04T17:45:00Z", searches: 3496, p50_ms: 3.365942862142778, p95_ms: 13.678415975875602 }, { window: "2026-09-04T18:00:00Z", searches: 4076, p50_ms: 3.1115444246013126, p95_ms: 11.452792540633903 }, { window: "2026-09-04T18:15:00Z", searches: 4625, p50_ms: 3.0673288650060386, p95_ms: 9.887544257560746 }, { window: "2026-09-04T18:30:00Z", searches: 5423, p50_ms: 2.9571019235647524, p95_ms: 8.91260938234503 }, { window: "2026-09-04T18:45:00Z", searches: 4934, p50_ms: 2.893294580750481, p95_ms: 8.34266539012987 } ] };
