pacnpal 1f0a2573c4 feat: Implement optimization plan for Markov Discord bot
- Added `optimization-plan.md` detailing strategies to reduce response latency and improve training throughput.
- Enhanced performance analysis in `performance-analysis.md` with identified bottlenecks and completed optimizations.
- Created `productContext.md` summarizing project goals, user scenarios, and implementation priorities.
- Developed `markov-store.ts` for high-performance serialized chain storage with alias method sampling.
- Implemented database performance indexes in `1704067200000-AddPerformanceIndexes.ts`.
- Introduced `markov-worker.ts` for handling CPU-intensive operations in separate threads.
- Established a worker pool in `worker-pool.ts` to manage multiple worker threads efficiently.

[MEMORY BANK: ACTIVE] productContext - Markov Discord

Date: 2025-09-25

Project: Markov Discord — lightweight Markov-chain based Discord responder

Summary:

  • This project builds and serves Markov chains derived from Discord message data to generate bot responses with low latency and high throughput.

Problem statement:

  • Current response generation and training paths can be CPU- and I/O-bound, causing high latency and slow bulk imports.

Goals & success metrics:

  • End-to-end response latency: target < 500ms (95th percentile).
  • Training throughput: target 1,000,000 messages/hour on dev hardware.
  • Memory during training: keep max heap < 2GB on 16GB host.

Primary users:

  • Bot maintainers and operators who run training and rollouts.
  • End-users in Discord guilds who interact with the bot.

Key usage scenarios:

  • Real-time response generation for user messages in active channels.
  • Bulk training/imports from historical message archives.
  • Canary rollouts to validate performance before global enablement.

Constraints & assumptions:

  • Runs primarily on single-node hosts with 16GB RAM (dev).
  • Uses SQLite as primary storage unless replaced per optimization plan.
  • Backwards compatibility required for serialization across releases.

Dependencies & related docs:

Implementation priorities (short):

  • Persist precomputed chains, alias sampling, worker threads, LRU cache.
  • See detailed tasks in the optimization plan linked above.

Operational notes:

  • Feature flags and toggles live in config/config.json.
  • Instrument metrics (latency histograms, cache hit ratio, DB durations).

Stakeholders & owners:

  • Owner: repository maintainer (designate as needed).

Open questions:

  • Confirm canary guild and traffic profile for 24h test.
