Improve restart recovery, snowflake batching, & CI#253
Merged
Conversation
Introduce restart-recovery improvements and various optimizations across the codebase. Key changes: reconcile and persist in-memory state-machine progress from persisted last_applied (KalamRaftStorage, RaftGroup, RaftManager) and emit clearer replication timeout details; commit last_applied while applying entries and return errors for apply failures to avoid silent progress. Add SnowflakeGenerator::next_ids_mapped to avoid intermediate allocations and wire it into system SeqId generation + new benchmarks and tests for mapped and concurrent generation. Fix embedded UI asset serving to avoid unnecessary copies, tweak websocket heartbeat handling, add deterministic initial-row sorting and tests, and adjust health monitor trimming logic. CI and developer tooling: set test env vars and add verification for TypeScript package test coverage in workflows, add new TypeScript ORM files and UI component updates, and change Docker base image to Ubuntu 24.04.
