From ebbf4cbd60075406bfdcb08a475491a198651fa7 Mon Sep 17 00:00:00 2001 From: zz_y Date: Mon, 11 May 2026 12:04:37 -0600 Subject: [PATCH] refactor(controller): trait impls + main.rs alias removal (PR #130 TODO 3+4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two of the four PR #130 follow-up TODOs land here. The other two are blocked by architectural reality (see below). ## TODO 3 — Placeholder traits made functional ✅ ### `OptimizerRule` trait - `controller/src/optimizer/trait_def.rs`: extended trait with `name()`, `category()`, `apply()`. Added two new `RuleCategory` variants (`Cse`, `Decorrelate`) beyond the original four. - `controller/src/optimizer/engine.rs`: per-rule `OptimizerRule` impls for all 12 engine rules (delegating to the existing `RewriteRule` free fns). New `default_rules_as_optimizer_rules()` helper returns `Vec>` for callers that want the trait surface. - `controller/src/optimizer/mod.rs`: blanket impl for every `sketch_algebra::rules::Rule` (lives outside sketch_algebra/ to respect Step #32's territory boundary). ### `PlanEmitter` trait - `controller/src/emit/trait_def.rs`: kept the associated-type shape; added 4 concrete impls — `OpampEmitter`, `OpampGatewayEmitter`, `StreamingConfigEmitter`, `InferenceConfigEmitter` — each wraps the existing free-function emitter. `InferenceConfigInput<'a>` bundles per-tenant routing inputs (tenant id + metric plans + Mode-3 metrics). `emit_borrowed` variant avoids forcing `'static` on the trait-method path. ### `DeploymentModelRegistry` - `controller/src/deployment_model.rs`: extended from stub `HashMap` to a real `HashMap<…, DeploymentModel>` where `DeploymentModel` owns `(id, rules: Vec>, emitters: EmitterSet)`. `Default::default()` registers `asaplifecycle` with the engine's 12-rule library + the 4 demo emitter names so `pipeline::run_pipeline` doesn't need manual registration. ## TODO 4 — main.rs migrated off back-compat aliases ✅ Rewrote all 52 reference sites in `controller/src/main.rs`: - `algebra::*` → `optimizer::engine::*` / `physical::*` / `intent_algebra::legacy_expr::*` (depending on context) - `analyzer::*` → `pipeline::*` - `config::*` → `emit::*` / `workload::*` - `planner::*` → `optimizer::*` / `physical::stage_split` / `optimizer::cost::online as online_cost_model` - `stage_split::*` → `physical::colored_dag::*` Removed all back-compat shims from `lib.rs`: - `pub use emit as config` - `pub use pipeline as analyzer` - `pub mod algebra { … }` - `pub use physical::colored_dag as stage_split` - `pub mod planner { … }` One leftover internal ref (`crate::planner::rules::bind_workload_typed` inside `emit/mod.rs::collect_metric_to_family`) retargeted to `crate::optimizer::rules::bind_workload_typed`. `lib.rs` shrank from 184 → 95 lines. ## TODO 1 — legacy_expr migration: BLOCKED 🚫 The canonical `intent_algebra::{query_expr,agg_intent,schema}` is NOT a structural superset of the legacy `intent_algebra::legacy_expr`. The canonical `QueryExpr` has 5 variants (`Scan`, `Window`, `Aggregate`, `LetBinding`, `Ref`); legacy has ~26 (`Source`, `Filter`, `Project`, `Aggregate`, `Window`, `SketchAgg`, `WindowedAgg`, `Partition`, `Dedup`, `TopK`, `Merge`, `Join`, `JoinSketch`, `SetOp`, `Sort`, `Limit`, `Subquery`, `LetBinding`, `WindowFunc`, `HistogramQuantile`, `PromQLSubquery`, `BinaryOp`, `Ref`) plus a full `ScalarExpr` IR (Column, Literal, BinaryOp, UnaryOp, FunctionCall, ScalarSubquery, InList, InSubquery, Between, IsNull, Case, Cast, VectorBinaryOp). The canonical IR's own module docs flag this: *"the full design.md list is larger; they are deferred to follow-up phases as the planner grows consumers for them"*. Migrating consumers requires first GROWING the canonical IR to absorb these variants — a substantial separate refactor, not a follow-up cleanup. 50+ consumer sites in query_parser/, language_logical_plan/, optimizer/engine.rs, physical/{allocator,planner,plan,stage_split}.rs depend on the legacy variant set. Recommend retitling the follow-up as "grow canonical L3 to absorb legacy variants" rather than "migrate consumers". The legacy_expr module stays in place pending that work. ## TODO 2 — stage_config.rs split: DEFERRED 🟡 The 3,020-line `emit/stage_config.rs` monolith mixes OTel YAML emit, backend JSON emit, and storage-routing emit with intricately shared helpers (`sketch_kind_to_processor_name`, `build_otlp_exporter`, `sketch_kind_tag`, …) and 1,580 lines of tightly-interleaved tests (line 1441 onward). The wrapper structs from TODO 3 above already provide the polymorphic `PlanEmitter` surface (`OpampEmitter` / `StreamingConfigEmitter` / `InferenceConfigEmitter`), so the file-level split is no longer load-bearing for the trait work. Recommend addressing as a separate PR with dedicated time budget if/when the monolith becomes a review-bottleneck. ## Build + test - `cargo build --release -p controller` — clean - `cargo build --release -p query_engine_rust` — clean - `cargo test --release -p controller --lib` — **646 passed** (was 633; +13 trait tests) - `cargo test --release -p controller --bin controller` — **27 passed** - `cargo test --release -p query_engine_rust --lib -- engines::warm_tier` — **13 passed** ## Caveat — `controller/src/store/` PR #130 left `lib.rs` declaring `pub mod store;` but `controller/src/store/` is in `.gitignore` (line ~10 of repo root .gitignore — the broad `store/` pattern). The directory is untracked; this needs a separate decision on whether it should be tracked or remain a runtime artifact. The build works because the directory exists locally on the dev box; fresh clones would fail. Not in scope for this PR; flagging as follow-up. ## Diff: 8 files, +785 / -207 Co-Authored-By: Claude Opus 4.7 (1M context) --- controller/src/deployment_model.rs | 227 ++++++++++++++++--- controller/src/emit/mod.rs | 7 +- controller/src/emit/trait_def.rs | 305 ++++++++++++++++++++++++-- controller/src/lib.rs | 103 +-------- controller/src/main.rs | 112 +++++----- controller/src/optimizer/engine.rs | 86 ++++++++ controller/src/optimizer/mod.rs | 21 ++ controller/src/optimizer/trait_def.rs | 131 +++++++++-- 8 files changed, 785 insertions(+), 207 deletions(-) diff --git a/controller/src/deployment_model.rs b/controller/src/deployment_model.rs index 00b67bbe9..59c86de77 100644 --- a/controller/src/deployment_model.rs +++ b/controller/src/deployment_model.rs @@ -1,17 +1,28 @@ -//! `DeploymentModelRegistry` + `DeploymentModelId` — placeholder -//! scaffolding for the design.md §5 `core::registry` surface. +//! `DeploymentModelRegistry` + `DeploymentModelId` + `DeploymentModel` +//! — the design.md §5 `core::registry` surface. //! -//!
