blog: Electric Circuits — turn any database query live#4728
Merged
Conversation
Adds the electric-ivm blog post covering the experimental DBSP-based rebuild of Electric: incremental view maintenance, the WAL tailer / query engine / fan-out split, subquery membership as a small always-on circuit, server-side aggregations, and measured memory results. Also adds a Demos page entry for LinearLite + the pipeline visualizer (no hosted instance — points at the repository and the blog post) and the post's diagrams/header image.

Remove the "Rebuilding Electric on DBSP and Durable Streams" (electric-ivm) post and its assets, and add the published "Introducing Electric Circuits" post: DBSP/Z-sets explainer, the subquery-pipeline worked example with a house-style dark diagram, the WAL-to-client path, and a neon banner.

The demo linked to /blog/2026/07/14/electric-ivm, which was removed; VitePress fails the build on the dead link. Point it at the replacement post /blog/2026/07/17/electric-circuits (frontmatter blog_post_url + inline link). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Benchmarks section: confirms the memory model's three claims with the 2026-07-21 shape-memory matrix runs (registration-only and fully materialized), rendered by a new MemoryMatrixChart component (grouped bars, Chart.js, same pattern as StorageComparisonChart). - The-query-becomes-a-circuit pass: Z-set/delta and stateless/stateful operator paragraphs tightened; move-in/move-out paragraph added and echoed in Circuits-hold-no-rows; shape API links. - subquery-pipeline.svg: sink box says "live query" instead of shape/s16.

… CTA rewrite - Benchmarks: charts placed at their explanation, claim order leads with memory-vs-data, honest note on the 7-9 KiB registration cost, Roaring bitmap link, informative chart titles. - IVM lede disambiguated (re-run vs apply); research-preview callout and Try it now rewritten around the clone-and-run CTA. - Move-in/move-out paragraph, state de-duplication section, Z-set and operator paragraphs tightened.

…ial pass - New title: "Electric Circuits: turn any database query live". - "Live context for the agent loop" section written: agent context = own history + domain database, both live via circuits; dynamic and expressive queries as requirements (context window budget, no over-sync). - Code-verified corrections: move-out also runs the indexed Postgres query (deletes gated by the per-query key bitmap); de-dup stated per query family instead of exact counts; materialized run scoped to the visibility queries. - Editorial pass applied (vocabulary, typos, repetitions); "Building on established foundations" removed; aggregation-sharing sentence restored; declare -> register; frontmatter description/excerpt updated; chart subtitles cleaned.

changed the title
…manual edits
- "circuit visualizer" used consistently across all five mentions.
- Try it now: repaired lead sentence, closing line added ("your app's
queries are already written").
- Materialized chart subtitle simplified.

…n polish - New architecture diagram (Postgres -> replication tailer -> circuits -> Durable Streams) and updated circuit diagram: theme cyan #75fbfd, OpenSauceOne embedded, white text, arch inner shapes white. - Demo videos embedded: membership flip (move-in/move-out) and circuit visualizer, looping, with posters; captions centered with margin. - Electric Circuits section: replication/streams named in the flow, DBSP moved to the IVM lineage paragraph; TanStack paragraph removed. - Benchmarks: single chart, memory-model intro made self-contained; bounded/materialized cuts; Roaring bitmaps in Circuits-hold-no-rows. - curl examples: single /shapes endpoint, no header, "select" field; Try it now lead and closing tightened.

Summary
Adds the blog post covering the experimental DBSP-based rebuild of Electric — incremental view maintenance, the WAL tailer / query engine / fan-out split, subquery membership served by a small always-on circuit, server-side aggregations, and measured memory results (flat resident memory as live shapes scale, bounded by what's distinct rather than by data size).
Also adds:
sync/demos/electric-ivm-linearlite.md). No hosted instance — it points at the repository (to clone and run) and the blog post, perDemoCTAs.vue's no-deployed_urlpath.architecture-v5-subquery.svg.Only these 5 files are included — this branch's working tree had a number of unrelated in-progress changes (sync-service test files, agent package tarballs, another draft blog post) that are intentionally left out of this PR.
