|
||||
|
||||
---
|
||||
|
||||
## ❌ What's Missing (Need to Create)
|
||||
|
||||
### 1. SQL Query Engine - **NOT IMPLEMENTED**
|
||||
**Status**: Need to build
|
||||
|
||||
**Options**:
|
||||
- **Option A**: Use `sqlparser-rs` (~200KB)
|
||||
- **Option B**: Build lightweight SQL subset parser (~50KB)
|
||||
- **Option C**: Skip SQL, use programmatic API only
|
||||
|
||||
**Recommendation**: Option A (full SQL compatibility)
|
||||
|
||||
### 2. SPARQL Engine - **PARTIALLY EXISTS**
|
||||
**Status**: Exists in `ruvector-postgres` but needs extraction
|
||||
|
||||
**Location**: `crates/ruvector-postgres/src/graph/sparql/`
|
||||
|
||||
**What Exists**:
|
||||
- ✅ SPARQL 1.1 parser (`parser.rs`)
|
||||
- ✅ SPARQL executor (`executor.rs`)
|
||||
- ✅ Triple store (`triple_store.rs`)
|
||||
- ✅ Result formatting (`results.rs`)
|
||||
|
||||
**Issues**:
|
||||
- ❌ Uses `pgrx` (PostgreSQL extension framework)
|
||||
- ❌ Tied to PostgreSQL storage
|
||||
|
||||
**Extraction Strategy**:
|
||||
1. Copy `sparql/` module from ruvector-postgres
|
||||
2. Remove `pgrx` dependencies
|
||||
3. Replace PostgreSQL storage with RvLite storage
|
||||
4. Wrap in WASM bindings
|
||||
|
||||
**Effort**: 2-3 days
|
||||
|
||||
### 3. Storage Engine - **PARTIALLY EXISTS**
|
||||
**Status**: Each crate has its own storage
|
||||
|
||||
**What Exists**:
|
||||
- `ruvector-wasm` → In-memory + IndexedDB
|
||||
- `ruvector-graph` → Graph storage
|
||||
- Need: **Unified storage layer**
|
||||
|
||||
**Recommendation**: Create thin adapter layer that routes:
|
||||
- Vector data → `ruvector-wasm`
|
||||
- Graph data → `ruvector-graph-wasm`
|
||||
- Triples → SPARQL triple store (extracted)
|
||||
|
||||
**Effort**: 1-2 days
|
||||
|
||||
### 4. Orchestration Layer - **NOT IMPLEMENTED**
|
||||
**Status**: Need to create
|
||||
|
||||
**Purpose**: Unified API that routes queries to appropriate engines
|
||||
|
||||
**Structure**:
|
||||
```rust
|
||||
pub struct RvLite {
|
||||
vector_db: Arc<VectorDB>, // From ruvector-wasm
|
||||
graph_db: Arc<GraphDB>, // From ruvector-graph-wasm
|
||||
gnn_engine: Arc<GnnEngine>, // From ruvector-gnn-wasm
|
||||
learning_engine: Arc<SonaEngine>, // From sona
|
||||
sparql_executor: Arc<SparqlExecutor>, // Extracted from postgres
|
||||
sql_executor: Arc<SqlExecutor>, // NEW
|
||||
}
|
||||
|
||||
impl RvLite {
|
||||
pub async fn query(&self, query: &str) -> Result<QueryResult> {
|
||||
// Route to appropriate engine based on query type
|
||||
if query.trim_start().starts_with("SELECT") {
|
||||
self.sql_executor.execute(query).await
|
||||
} else if query.trim_start().starts_with("MATCH") {
|
||||
self.graph_db.cypher(query).await
|
||||
} else if query.trim_start().starts_with("PREFIX") {
|
||||
self.sparql_executor.execute(query).await
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Effort**: 2-3 days

## 💡 Key Implementation Insights
|
||||
|
||||
### 1. RvLite = Thin Orchestration Layer
|
||||
|
||||
**NOT**: Reimplementing everything
|
||||
**YES**: Composing existing WASM crates
|
||||
|
||||
```rust
|
||||
// RvLite doesn't reimplement - it orchestrates!
|
||||
#[wasm_bindgen]
|
||||
pub struct RvLite {
|
||||
// Delegate to existing implementations
|
||||
vectors: VectorDB, // From ruvector-wasm
|
||||
graph: GraphDB, // From ruvector-graph-wasm
|
||||
gnn: GnnEngine, // From ruvector-gnn-wasm
|
||||
learning: SonaEngine, // From sona
|
||||
|
||||
// Only NEW components
|
||||
sql: SqlExecutor, // NEW
|
||||
sparql: SparqlExecutor, // Extracted
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Unified API Pattern
|
||||
|
||||
```typescript
|
||||
// Single entry point
|
||||
const db = await RvLite.create();
|
||||
|
||||
// Automatically routes to correct engine
|
||||
await db.query(`SELECT * FROM docs ORDER BY embedding <=> $1`); // → SQL
|
||||
await db.query(`MATCH (a)-[:KNOWS]->(b) RETURN a, b`); // → Cypher
|
||||
await db.query(`SELECT ?s ?p ?o WHERE { ?s ?p ?o }`); // → SPARQL
|
||||
```
|
||||
|
||||
### 3. Zero-Copy Data Sharing
|
||||
|
||||
```rust
|
||||
// Share storage between engines
|
||||
struct SharedStorage {
|
||||
vectors: Arc<VectorStorage>, // From ruvector-wasm
|
||||
graph: Arc<GraphStorage>, // From ruvector-graph
|
||||
triples: Arc<TripleStore>, // From SPARQL
|
||||
}
|
||||
|
||||
// SQL can query vectors stored by vector engine
|
||||
// Cypher can use vectors from vector engine
|
||||
// SPARQL can reference graph nodes
|
||||
```
|
||||
|
||||

||||

||||
## 📈 Revised Size Estimate
|
||||
|
||||
| Component | Size (gzipped) |
|
||||
|-----------|----------------|
|
||||
| ruvector-wasm | 500KB |
|
||||
| ruvector-graph-wasm (Cypher) | 600KB |
|
||||
| ruvector-gnn-wasm | 300KB |
|
||||
| sona (learning) | 300KB |
|
||||
| SQL engine (sqlparser-rs) | 200KB |
|
||||
| SPARQL executor (extracted) | 300KB |
|
||||
| RvLite orchestration | 100KB |
|
||||
| **Total** | **~2.3MB** |
|
||||
|
||||
**Original Estimate**: 5-6MB
|
||||
**Revised with Reuse**: **2-3MB** ✅
