It allows producers to publish messages with a relative delay, and ensures they are dispatched to consumers when their delay expires. +Built with strong consistency, durability, and high availability in mind, FutureQ leverages a powerful embedded storage engine and a robust Raft consensus implementation to provide a reliable messaging backbone for modern distributed systems. + +## Key Features + +* **Delayed Messaging**: Enqueue messages to be delivered after a specific `delay_ms`. +* **Durable Storage**: Uses [Pebble](https://github.com/cockroachdb/pebble) (CockroachDB's embedded LSM key-value store) for extremely fast and reliable disk-backed storage. +* **High Availability & Replication**: Employs [Dragonboat](https://github.com/lni/dragonboat) for Raft consensus, ensuring data is replicated and safe across cluster nodes. +* **High Throughput**: Supports batch publishing and batch acknowledgements to minimize Raft and storage overhead. +* **Consumer Groups & Topics**: Supports topic-based routing with fan-out across multiple consumer groups, and competing consumers (round-robin) within a single group. +* **gRPC Transport**: Uses efficient bidirectional gRPC streams for both producing and consuming messages. +* **Automatic Cluster Membership**: Uses HashiCorp's `memberlist` (gossip protocol) for automatic node discovery and cluster scaling. +* **Message Expiry (TTL)**: Native support for message Time-To-Live, automatically cleaning up expired messages that haven't been consumed. +* **Observability**: Exposes Prometheus metrics for deep visibility into queue performance, Raft latency, and consumer lag. + +## Architecture + +FutureQ operates as a cluster of nodes where one node acts as the Raft Leader, and others as Followers. +Producers and consumers connect via gRPC. + +### Core Components: + +* **Storage (`internal/storage`)**: Interfaces with Pebble DB. The key schema is heavily optimized for time-based range scans: `[bucket][topic_hash][event_id]`. +* **Consensus (`internal/raft`)**: Defines the Raft State Machine and handles replicated commands (like `StoreBatchCmd` and `DeleteBatchCmd`). +* **Dispatcher (`internal/dispatcher`)**: The heart of the broker. It continuously scans the time buckets in Pebble for messages whose delay has expired, tracking active topics via the Hub. +* **Hub (`internal/dispatcher/hub.go`)**: Manages connected consumers, mapping them by `(topic, group_id)`, and handles round-robin message delivery. +* **API (`internal/api`)**: gRPC services (`FutureQProducer`, `FutureQConsumer`, `FutureQCluster`). + +## Project Structure + +```text +. +├── cmd/ # Application entrypoints (start, root commands) +├── config/ # Configuration loading and default values (YAML/Env) +├── internal/ +│ ├── api/ # gRPC service handlers (producer, consumer, cluster) +│ ├── app/ # Application lifecycle management +│ ├── dispatcher/ # Message dispatching, consumer hub, janitor, and deleter +│ ├── membership/ # Gossip protocol integration (memberlist) +│ ├── metrics/ # Prometheus metrics collection +│ ├── raft/ # Dragonboat Raft state machine and commands +│ └── repository/ # Key schema and database interaction logic +├── pkg/ # Reusable utilities (logging, xxhash wrapper, key encoding) +├── config.example.yaml # Example configuration file with detailed comments +└── plann.md # Redesign plan and architectural decisions +``` + +## Getting Started + +1. **Clone the repository**: + ```bash + git clone https://github.com/futureq-io/futureq.git + cd futureq + ``` + +2. **Configuration**: + Copy `config.example.yaml` to `config.yaml` and adjust settings as needed (e.g., node ID, listen addresses). + +3. **Run the Server**: + ```bash + go run cmd/main.go start --config config.yaml + ``` + +## Roadmap + +* **Sharding**: Support for multiple Raft shards across a large cluster. +* **Follower Reads**: Allowing consumers to read from replica nodes to reduce load on the leader. +* **Security**: Implement mTLS for gRPC communication and token-based ACLs for topics. +* **Dead-Letter Queues (DLQ)**: Automatic routing of messages that fail processing multiple times. diff --git a/go.mod b/go.mod index e9a1cf3..5299349 100644 --- a/go.mod +++ b/go.mod @@ -3,10 +3,13 @@ module github.com/futureq-io/futureq go 1.26.2 require ( + github.com/cespare/xxhash/v2 v2.3.0 github.com/cockroachdb/pebble/v2 v2.1.6 -

It is **always anchored** (a `target` file path or symbol, resolved like `context`) and has two modes: + +- `pdg_query { mode: "controls", target: "..." }` — CDG: "under what condition does X run?". Each edge is a controlling predicate block → dependent block with the branch sense (`'T'`/`'F'`) in `reason`; an edge into an early `return`/`throw` is flagged `guard: true` (guard-clause discovery — the sense depends on the predicate, so don't filter guards by a fixed label). +- `pdg_query { mode: "flows", target: "...", variable?: "..." }` — REACHING_DEF def→use edges within the function; pass `variable` to trace one binding. + +A repo indexed without `--pdg` returns a "no PDG layer" note (or "status unknown" when the layer can't be confirmed). Intra-procedural only — cross-function flow is taint's domain (`explain`). The raw CDG/REACHING_DEF edges are also queryable via `cypher`. See the `gitnexus-pdg-query` skill for the full query surface. + +### Shortest path between two symbols (`trace`) + +`trace` answers "how does A reach B?" in one call — the shortest directed path over `CALLS` (plus `HAS_METHOD`, so a class-rooted trace descends into its methods) instead of chaining 3–8 `context`/`impact` hops by hand. + +- `trace { from: "validateUser", to: "executeQuery" }` — shortest path between two symbols. +- Disambiguate common names with `from_uid`/`to_uid` (zero-ambiguity) or `from_file`/`to_file`; an ambiguous name returns ranked candidates. +- `maxDepth` (default 10, max 30) bounds the search; `includeTests` (default false) lets the traversal pass through test-file symbols. + +Returns ordered `hops` (each `{ name, filePath, startLine }`) and an aligned `edges[]` of `{ relType, confidence }`, so call hops and containment (`HAS_METHOD`) hops stay distinguishable. When no path exists it reports the **furthest** reachable node (where the chain breaks) and sets `truncated: true` if a traversal cap was hit first.

It takes optional `limit` (default **50**, max **200**) and `offset`, and returns: - -```jsonc -{ - "repositories": [ - { "name": "...", "path": "...", "indexedAt": "...", "lastCommit": "...", "stats": { } } - ], - "pagination": { - "total": 437, - "limit": 50, - "offset": 0, - "returned": 50, - "hasMore": true, - "nextOffset": 50 - } -} -``` - -To enumerate **every** repository, keep calling with `offset` set to `pagination.nextOffset` until `hasMore` is `false`: - -```text -list_repos {} → repos 1–50, nextOffset 50, hasMore true -list_repos { offset: 50 } → repos 51–100, nextOffset 100, hasMore true -… -list_repos { offset: 400 } → repos 401–437, hasMore false (done) -``` - -Notes: `offset` ≥ `total` returns an empty page (with `total` still reported). Out-of-range or malformed `limit`/`offset` (non-integer, `limit` outside `[1, 200]`, `offset < 0`) are rejected with a clear error — `limit` above the max is rejected, not silently capped. The order is deterministic (lower-cased name, then path), so paging never skips or duplicates an entry while the registry is unchanged. - -### Taint findings (`explain`) - -`explain` returns taint findings recorded by `gitnexus analyze --pdg` — intra-procedural `TAINTED` edges plus cross-function `TAINT_PATH` hops where the interprocedural taint phase found a function-level source→sink chain. Each finding includes a sink category (command-injection, code-injection, path-traversal, sql-injection, xss), source/sink lines, and the ordered hop path with the variable carried on each hop. - -- `explain {}` — enumerate all findings for the repo (bounded by `limit`, deterministic order) -- `explain { target: "src/vuln.ts" }` — findings in a file (suffix path match accepted) -- `explain { target: "runUserCommand" }` — findings in a function (resolved like `context`; ambiguous names return ranked candidates) - -A repo indexed without `--pdg` returns a clear "no taint layer" note. Caveats: closure/callback, property/field, and implicit flows are not modeled, and interprocedural findings are function-level `TAINT_PATH` hops rather than statement-level path proof, so the absence of a finding is **not** proof of safety. `SANITIZES` (sanitizer-kill) edges are queryable via `cypher`. - -### Control & data dependence (`pdg_query`) - -`pdg_query` reads the control/data-dependence layers `gitnexus analyze --pdg` records (CDG + REACHING_DEF, basic-block granular) — the control/data analog of `explain`. It is **always anchored** (a `target` file path or symbol, resolved like `context`) and has two modes: - -- `pdg_query { mode: "controls", target: "..." }` — CDG: "under what condition does X run?". Each edge is a controlling predicate block → dependent block with the branch sense (`'T'`/`'F'`) in `reason`; an edge into an early `return`/`throw` is flagged `guard: true` (guard-clause discovery — the sense depends on the predicate, so don't filter guards by a fixed label). -- `pdg_query { mode: "flows", target: "...", variable?: "..." }` — REACHING_DEF def→use edges within the function; pass `variable` to trace one binding. - -A repo indexed without `--pdg` returns a "no PDG layer" note (or "status unknown" when the layer can't be confirmed). Intra-procedural only — cross-function flow is taint's domain (`explain`). The raw CDG/REACHING_DEF edges are also queryable via `cypher`. See the `gitnexus-pdg-query` skill for the full query surface. - -### Shortest path between two symbols (`trace`) - -`trace` answers "how does A reach B?" in one call — the shortest directed path over `CALLS` (plus `HAS_METHOD`, so a class-rooted trace descends into its methods) instead of chaining 3–8 `context`/`impact` hops by hand. - -- `trace { from: "validateUser", to: "executeQuery" }` — shortest path between two symbols. -- Disambiguate common names with `from_uid`/`to_uid` (zero-ambiguity) or `from_file`/`to_file`; an ambiguous name returns ranked candidates. -- `maxDepth` (default 10, max 30) bounds the search; `includeTests` (default false) lets the traversal pass through test-file symbols. - -Returns ordered `hops` (each `{ name, filePath, startLine }`) and an aligned `edges[]` of `{ relType, confidence }`, so call hops and containment (`HAS_METHOD`) hops stay distinguishable. When no path exists it reports the **furthest** reachable node (where the chain breaks) and sets `truncated: true` if a traversal cap was hit first. Every result carries a `status`: `ok` / `no_path` / `ambiguous` / `not_found` / `error`. - -Cross-repo (experimental): pass `repo: "@groupName"` to trace across a group's member repos — the path may cross **one** `ContractLink` boundary (reported as a `CONTRACT_LINK` hop with the bridged contract in `crossings[]`). Omit `to` entirely to follow `from`'s outgoing HTTP call to whatever provider endpoint it lands on. Groups are configured via `group_list` / `group_sync`. - -## Resources Reference - -Lightweight reads (~100-500 tokens) for navigation: - -| Resource | Content | -| ---------------------------------------------- | ----------------------------------------- | -| `gitnexus://repo/{name}/context` | Stats, staleness check | -| `gitnexus://repo/{name}/clusters` | All functional areas with cohesion scores | -| `gitnexus://repo/{name}/cluster/{clusterName}` | Area members | -| `gitnexus://repo/{name}/processes` | All execution flows | -| `gitnexus://repo/{name}/process/{processName}` | Step-by-step trace | -| `gitnexus://repo/{name}/schema` | Graph schema for Cypher | - -## Graph Schema - -**Nodes:** File, Folder, Function, Class, Interface, Method, CodeElement, Community, Process, Route, Tool, plus language-specific types (Struct, Enum, Trait, Impl, Namespace, Module, …) and BasicBlock (`--pdg` indexes only).
