Project State

Project Reference

See: .planning/PROJECT.md (updated 2026-03-11)

Core value: Users can reliably search and find any transaction across all connected Camel instances -- by any combination of state, time, duration, or content -- even at millions of transactions per day with 30-day retention. Current focus: Phase 2: Transaction Search + Diagrams

Current Position

Phase: 2 of 4 (Transaction Search + Diagrams) Plan: 2 of 3 in current phase Status: Plan 02-02 Complete Last activity: 2026-03-11 -- Completed 02-02 (ELK diagram rendering, SVG/JSON content negotiation, 15 tests)

Progress: [██████----] 67%

Accumulated Context

Decisions

Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:

[Roadmap]: ClickHouse chosen as primary store (research recommendation, HIGH confidence)
[Roadmap]: Full-text search starts with ClickHouse skip indexes (tokenbf_v1), OpenSearch deferred
[Roadmap]: Phases 2 and 3 can execute in parallel (both depend only on Phase 1)
[Roadmap]: Web UI deferred to v2
[Phase 01]: Used spring-boot-starter-jdbc for JdbcTemplate + HikariCP auto-config
[Phase 01]: Created MetricsSnapshot record in core module (cameleer3-common has no metrics model)
[Phase 01]: Upgraded testcontainers to 2.0.3 for Docker Desktop 29.x compatibility
[Phase 01]: Changed error_message/error_stacktrace to non-nullable String for tokenbf_v1 index compat
[Phase 01]: TTL expressions require toDateTime() cast for DateTime64 columns in ClickHouse 25.3
[Phase 01]: Controllers accept raw String body to support both single and array JSON payloads
[Phase 01]: IngestionService is a plain class in core module, wired as bean by IngestionBeanConfig in app
[Phase 01]: Removed @Configuration from IngestionConfig to fix duplicate bean with @EnableConfigurationProperties
[Phase 02]: FlatProcessor record captures depth and parentIndex during DFS traversal
[Phase 02]: Exchange bodies/headers concatenated into single String columns for LIKE search
[Phase 02]: Headers serialized to JSON via Jackson ObjectMapper (static instance)
[Phase 02]: DiagramRenderer/DiagramLayout stubs created to resolve pre-existing compilation blocker
[Phase 02]: ELK layered algorithm with top-to-bottom direction for route diagram layout
[Phase 02]: JFreeSVG over Batik for lightweight server-side SVG generation
[Phase 02]: Manual Accept header parsing -- JSON only when first preference, SVG as default
[Phase 02]: xtext xbase lib required at runtime by ELK 0.11.0 LayeredMetaDataProvider
[Phase 02]: Compound node children detected from RouteNode.getChildren() (matches agent graph model)

Pending Todos

None yet.

Blockers/Concerns

[Phase 1]: ClickHouse Java client API needs phase-specific research (library has undergone changes)
[Phase 1]: Must read cameleer3-common PROTOCOL.md before designing ClickHouse schema
[Phase 2]: Diagram rendering library selection is an open question (Batik, jsvg, JGraphX, or client-side)
[Phase 2]: ClickHouse skip indexes may not suffice for full-text; decision point during Phase 2
