Marks Sketches A and B done, with a note that A took the simpler Channel.UNLIMITED + AtomicInteger cap path the original Risks section called out, sidestepping the channel-swap that the plan first sketched. Records that the streaming-filter slice of Sketch C landed in Quartz, and that the larger envelope-streaming work the plan called out is unnecessary because MessageDeserializer / CommandDeserializer / EventDeserializer were already streaming — only the filter sub-object went through readTree. Adds the verification benchmarks (connectionsHeldOpen10k, connectionsHeldOpenWithFanout) to the verification section, with a correction that what's measured is JVM heap not OS RSS. Carries forward the not-done items (fan-out de-duplication, filter-matching index, Netty engine) into the open-work section, pointing at live-broadcast-fanout-index.md for the highest-leverage remaining work.
geode plans
Performance-focused design docs for future work. Each file is a self-contained sketch — problem statement, observed numbers, proposed fix, how to verify, risks. None of these are committed work; they're the queue.
Ordered roughly by expected impact:
| Plan | Headline gain |
|---|---|
| 2026-05-07-event-ingestion-batching.md | 5–10× write EPS via SQLite group commit + ingest pipelining |
| 2026-05-07-live-broadcast-fanout-index.md | >10× fanout speedup at >2 000 subscribers |
| 2026-05-07-connection-scaling.md | 2 000 → 10 000+ concurrent connections |
| 2026-05-07-negentropy-large-corpus.md | 25× lower memory + faster NEG-OPEN on M-event corpora |
Verification target for each plan is a new method on
geode.perf.LoadBenchmark (gated by -DrunLoadBenchmark=true) so
regressions show up in the regular CI matrix once they're enabled.
