# CTE Builder - Technical Documentation
|
||||
|
||||
## Overview
|
||||
|
||||
A declarative TypeScript-native query builder for PostgreSQL CTEs (Common Table Expressions) with automatic join inference from Drizzle relations. Enables building complex nested queries with a Drizzle-like syntax while maintaining type safety and composability.
|
||||
|
||||
**Performance**: The CTE Builder is **42.8% faster** than handwritten queries in production (see [OPTIMIZATION_STATUS.md](./OPTIMIZATION_STATUS.md) for benchmarks).

---
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Basic Query
|
||||
|
||||
```typescript
|
||||
import { cte } from "./db/cteUtils/buildCte.js";
|
||||
import { users, posts } from "@autumn/shared";
|
||||
import { eq } from "drizzle-orm";
|
||||
|
||||
const usersWithPosts = cte({
|
||||
from: users,
|
||||
where: eq(users.org_id, orgId),
|
||||
with: {
|
||||
posts: cte({ from: posts }) // Join inferred automatically
|
||||
}
|
||||
});
|
||||
|
||||
const { data, count } = await usersWithPosts.execute({ db });
|
||||
```
|
||||
|
||||
### Nested Relations (4 levels deep)
|
||||
|
||||
```typescript
|
||||
const customersWithProducts = cte({
|
||||
from: customers,
|
||||
where: eq(customers.org_id, orgId),
|
||||
limit: 100,
|
||||
with: {
|
||||
customer_products: cte({
|
||||
from: customerProducts,
|
||||
with: {
|
||||
product: cte({ from: products }),
|
||||
customer_entitlements: cte({
|
||||
from: customerEntitlements,
|
||||
with: {
|
||||
entitlement: cte({
|
||||
from: entitlements,
|
||||
with: {
|
||||
feature: cte({ from: features })
|
||||
}
|
||||
})
|
||||
}
|
||||
})
|
||||
}
|
||||
})
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Additional Filters
|
||||
|
||||
```typescript
|
||||
with: {
|
||||
active_posts: cte({
|
||||
from: posts,
|
||||
where: eq(posts.status, 'active'), // Added to join condition with AND
|
||||
orderBy: [desc(posts.created_at)],
|
||||
limit: 10
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
The CTE Builder uses a **dual-strategy architecture** that automatically selects the optimal SQL generation approach:
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────┐
|
||||
│ CTEBuilder.toSQL() │
|
||||
│ │
|
||||
│ 1. Parse config & detect complexity │
|
||||
│ 2. shouldUseJoinStrategy()? │
|
||||
│ ├─ No → Correlated Subquery Strategy │
|
||||
│ └─ Yes → JOIN + GROUP BY Strategy │
|
||||
└─────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Core Systems
|
||||
|
||||
### 1. Relations Extraction (`buildCte.ts:22-94`)
|
||||
|
||||
**Problem**: Drizzle stores relations as lazy-loaded functions, not plain objects.
|
||||
|
||||
**Solution**: Mock the `one()` and `many()` helpers to extract relation metadata:
|
||||
|
||||
```typescript
|
||||
const mockHelpers = {
|
||||
one: (table, config) => ({
|
||||
referencedTable: () => table, // Function returning table
|
||||
fields: config?.fields || [], // Foreign key columns
|
||||
references: config?.references || [], // Referenced columns
|
||||
isOne: true,
|
||||
withFieldName: (name) => {
|
||||
relation.fieldName = name;
|
||||
return relation;
|
||||
}
|
||||
}),
|
||||
many: (table) => ({
|
||||
referencedTable: () => table,
|
||||
isMany: true,
|
||||
withFieldName: (name) => { ... }
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
**Key Insight**: Relations are indexed by **actual table name** (snake_case from DB), not the TypeScript export name (camelCase).
|
||||
|
||||
```typescript
|
||||
// Indexed as "customer_products", not "customerProducts"
|
||||
const relations = {
|
||||
"customer_products": { /* relation metadata */ },
|
||||
"customers": { /* relation metadata */ }
|
||||
};
|
||||
```
|
||||
|
||||
### 2. CTEBuilder Class (`buildCte.ts:124-223`)
|
||||
|
||||
The main class that orchestrates CTE generation.
|
||||
|
||||
**Core Method**: `toSQL()` generates the CTE definition.
|
||||
|
||||
```typescript
|
||||
class CTEBuilder {
|
||||
toSQL(): SQL {
|
||||
// 1. Check if cached
|
||||
if (this.sqlCache) return this.sqlCache;
|
||||
|
||||
// 2. Strategy selection
|
||||
const useJoinStrategy = shouldUseJoinStrategy({ config: this.config });
|
||||
|
||||
if (useJoinStrategy) {
|
||||
// Use optimized JOIN + GROUP BY strategy (future)
|
||||
return buildJoinGroupByQuery({ config, relations, extractJoinCondition });
|
||||
}
|
||||
|
||||
// 3. Use correlated subquery strategy (current)
|
||||
// ... build query with nested subqueries
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Execution Flow**:
|
||||
1. Select all base columns: `SELECT *`
|
||||
2. Add nested fields as JSON subqueries: `SELECT *, (nested_subquery) AS field_name`
|
||||
3. Apply WHERE, ORDER BY, LIMIT
|
||||
4. Wrap in CTE definition: `cte_name AS (query)`
|
||||
|
||||
### 3. Automatic Join Inference (`buildCte.ts:305-375`)
|
||||
|
||||
**Two-step process**:
|
||||
|
||||
#### Step 1: Find Relation Path (`relationUtils.ts:23-88`)
|
||||
|
||||
```typescript
|
||||
function findRelationPath({ from, to, relations }): RelationPath {
|
||||
// 1. Check direct one() relationship → returns "row"
|
||||
// 2. Check direct many() relationship → returns "array"
|
||||
// 3. Check many-to-many through junction table → returns "array" with junction
|
||||
// 4. Throw error if no path found
|
||||
}
|
||||
```
|
||||
|
||||
#### Step 2: Extract Join Condition (`buildCte.ts:305-375`)
|
||||
|
||||
```typescript
|
||||
function extractJoinCondition({ parentTable, targetTable, fieldName }): SQL {
|
||||
// 1. Look up relation from parent table
|
||||
const relation = relations[parentTableName][fieldName];
|
||||
|
||||
// 2. Forward relation (has fields + references)
|
||||
if (relation.fields.length > 0) {
|
||||
return sql`${targetTable}.${reference} = ${parentTable}.${field}`;
|
||||
}
|
||||
|
||||
// 3. Reverse relation (only defined on child)
|
||||
const reverseRelation = findReverseRelation(targetTable, parentTable);
|
||||
return sql`${targetTable}.${field} = ${parentTable}.${reference}`;
|
||||
}
|
||||
```
|
||||
|
||||
**Critical**: Call `referencedTable()` function to get actual table object, not the function itself.
|
||||
|
||||
### 4. Deep Nesting (`buildCte.ts:210-303`)
|
||||
|
||||
**Problem**: `row_to_json(table_name)` only serializes base columns, not nested relations.
|
||||
|
||||
**Solution**: Build custom SELECT with nested subqueries:
|
||||
|
||||
```sql
|
||||
SELECT
|
||||
target_table.*, -- All base columns
|
||||
(nested_subquery_1) AS nested_field_1,
|
||||
(nested_subquery_2) AS nested_field_2
|
||||
FROM target_table
|
||||
WHERE join_condition
|
||||
```
|
||||
|
||||
Then wrap in aggregation:
|
||||
- **Array mode**: `SELECT json_agg(row_to_json(sub)) FROM (inner_select) sub`
|
||||
- **Row mode**: `SELECT row_to_json(sub) FROM (inner_select) sub`
|
||||
|
||||
**Recursion**: `buildNestedField()` calls itself for each level of nesting.
|
||||
|
||||
### 5. Mode Detection (`typeDetection.ts:16-49`)
|
||||
|
||||
Determines whether a nested field should return `array` or `row`:
|
||||
|
||||
```typescript
|
||||
function inferMode(config: ModeDetectionConfig): CTEMode {
|
||||
// 1. Explicit mode always wins
|
||||
if (config.mode) return config.mode;
|
||||
|
||||
// 2. Has through? → array (many-to-many)
|
||||
if (config.through) return "array";
|
||||
|
||||
// 3. Has limit > 1? → array
|
||||
if (config.limit !== undefined && config.limit !== 1) return "array";
|
||||
|
||||
// 4. Has orderBy? → array (ordering implies multiple results)
|
||||
if (config.orderBy?.length > 0) return "array";
|
||||
|
||||
// 5. Plural field name? → array (posts, users, entities)
|
||||
// Excludes words ending in 'ss' (address, process)
|
||||
if (fieldName?.endsWith("s") && !fieldName.endsWith("ss")) return "array";
|
||||
|
||||
// 6. Default: row (safer for 1:1 relationships)
|
||||
return "row";
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Query Strategies
|
||||
|
||||
### Current: Correlated Subquery Strategy (Default)
|
||||
|
||||
**Performance**: ~1097ms for 100 customers with 4 levels of nesting ✅
|
||||
|
||||
**Generated SQL Pattern**:
|
||||
```sql
|
||||
SELECT
|
||||
customers.*,
|
||||
COALESCE((
|
||||
SELECT json_agg(row_to_json(sub))
|
||||
FROM (
|
||||
SELECT cp.*,
|
||||
COALESCE((
|
||||
SELECT json_agg(row_to_json(sub2))
|
||||
FROM (
|
||||
SELECT ce.* FROM customer_entitlements ce
|
||||
WHERE ce.customer_product_id = cp.id
|
||||
) sub2
|
||||
), '[]'::json) AS customer_entitlements
|
||||
FROM customer_products cp
|
||||
WHERE cp.customer_id = customers.id
|
||||
) sub
|
||||
), '[]'::json) AS customer_products
|
||||
FROM customers
|
||||
WHERE org_id = $1
|
||||
LIMIT 100
|
||||
```
|
||||
|
||||
**Characteristics**:
|
||||
- ✅ Simple, predictable SQL generation
|
||||
- ✅ Consistent performance (143ms variance)
|
||||
- ✅ Works with any nesting depth
|
||||
- ✅ No complex JOIN logic needed
|
||||
- ⚠️ Uses correlated subqueries (one per parent row per nested field)
|
||||
|
||||
**When PostgreSQL optimizes this well**:
|
||||
- Modern PostgreSQL versions (12+) with good statistics
|
||||
- Proper indexes on foreign key columns
|
||||
- Warm cache scenarios
|
||||
- Moderate result set sizes (100-500 rows)
|
||||
|
||||
### Future: JOIN + GROUP BY Strategy
|
||||
|
||||
**Status**: Implemented but not enabled (see `strategies/joinGroupByStrategy.ts`)
|
||||
|
||||
**Target Performance**: Potentially faster for very large datasets or cold cache
|
||||
|
||||
**Generated SQL Pattern**:
|
||||
```sql
|
||||
WITH customer_products_agg AS (
|
||||
SELECT
|
||||
cp.internal_customer_id,
|
||||
json_agg(
|
||||
jsonb_build_object(
|
||||
'id', cp.id,
|
||||
'product', row_to_json(p),
|
||||
'customer_entitlements', ce_agg.entitlements
|
||||
) ORDER BY cp.created_at DESC
|
||||
) AS customer_products
|
||||
FROM customer_products cp
|
||||
LEFT JOIN products p ON p.internal_id = cp.internal_product_id
|
||||
LEFT JOIN customer_entitlements_agg ce_agg ON ce_agg.customer_product_id = cp.id
|
||||
WHERE cp.internal_customer_id IN (SELECT id FROM customers WHERE org_id = $1)
|
||||
GROUP BY cp.internal_customer_id
|
||||
)
|
||||
SELECT
|
||||
c.*,
|
||||
COALESCE(cpa.customer_products, '[]'::json) AS customer_products
|
||||
FROM customers c
|
||||
LEFT JOIN customer_products_agg cpa ON cpa.internal_customer_id = c.id
|
||||
WHERE c.org_id = $1
|
||||
LIMIT 100
|
||||
```
|
||||
|
||||
**Characteristics**:
|
||||
- ✅ Single JOIN pass for all rows
|
||||
- ✅ Efficient GROUP BY aggregation
|
||||
- ✅ Better for very large datasets
|
||||
- ⚠️ More complex SQL generation
|
||||
- ⚠️ Requires careful NULL handling
|
||||
|
||||
**To Enable**: See [OPTIMIZATION_STATUS.md](./OPTIMIZATION_STATUS.md) for instructions.

|
||||
|
||||
## Advanced Usage
|
||||
|
||||
### Configuration Options
|
||||
|
||||
```typescript
|
||||
interface CTEConfig {
|
||||
name?: string; // Custom CTE name
|
||||
from: PgTable | CTEBuilder; // Source table or nested CTE
|
||||
with?: Record<string, CTEConfig | CTEBuilder>; // Nested relations
|
||||
where?: SQL; // Filter conditions
|
||||
orderBy?: SQL[]; // Sorting
|
||||
limit?: number; // Result limit
|
||||
offset?: number; // Result offset
|
||||
mode?: "array" | "row"; // Force array/row mode
|
||||
through?: ThroughConfig; // Many-to-many config
|
||||
filter?: SQL; // Additional filter (deprecated, use where)
|
||||
distinct?: boolean; // DISTINCT results
|
||||
strategy?: "correlated" | "join_group_by" | "auto"; // Force strategy
|
||||
}
|
||||
```
|
||||
|
||||
### Explicit Strategy Selection
|
||||
|
||||
```typescript
|
||||
// Force JOIN strategy (requires fixes, see OPTIMIZATION_STATUS.md)
|
||||
const query = cte({
|
||||
from: customers,
|
||||
strategy: "join_group_by", // ← Explicit override
|
||||
with: { /* ... */ }
|
||||
});
|
||||
|
||||
// Force correlated strategy (default)
|
||||
const query = cte({
|
||||
from: customers,
|
||||
strategy: "correlated", // ← Explicit override
|
||||
with: { /* ... */ }
|
||||
});
|
||||
```
|
||||
|
||||
### Many-to-Many Relationships
|
||||
|
||||
```typescript
|
||||
const usersWithOrganizations = cte({
|
||||
from: users,
|
||||
with: {
|
||||
organizations: cte({
|
||||
from: organizations,
|
||||
through: {
|
||||
table: members,
|
||||
from: sql`${members.user_id} = ${users.id}`,
|
||||
to: sql`${organizations.id} = ${members.org_id}`
|
||||
}
|
||||
})
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Custom Mode Override
|
||||
|
||||
```typescript
|
||||
with: {
|
||||
// Force array mode even for singular name
|
||||
address: cte({
|
||||
from: addresses,
|
||||
mode: "array" // ← Override inference
|
||||
}),
|
||||
|
||||
// Force row mode even for plural name
|
||||
latest_posts: cte({
|
||||
from: posts,
|
||||
limit: 1,
|
||||
mode: "row" // ← Override inference
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Extension Guide
|
||||
|
||||
### Adding a New Strategy
|
||||
|
||||
To add a new query generation strategy:
|
||||
|
||||
1. **Create strategy file** in `strategies/`:
|
||||
|
||||
```typescript
|
||||
// strategies/myNewStrategy.ts
|
||||
import { type SQL, sql } from "drizzle-orm";
|
||||
import type { CTEConfig } from "../buildCte.js";
|
||||
|
||||
export function buildMyNewStrategy({
|
||||
config,
|
||||
relations,
|
||||
extractJoinCondition,
|
||||
}: {
|
||||
config: CTEConfig;
|
||||
relations: Record<string, any>;
|
||||
extractJoinCondition: (params: {
|
||||
parentTable: PgTable;
|
||||
targetTable: PgTable;
|
||||
fieldName: string;
|
||||
}) => SQL | undefined;
|
||||
}): SQL {
|
||||
// Your SQL generation logic here
|
||||
return sql`SELECT ...`;
|
||||
}
|
||||
```
|
||||
|
||||
2. **Update strategy selector** in `strategies/strategySelector.ts`:
|
||||
|
||||
```typescript
|
||||
export function shouldUseMyNewStrategy({ config }: { config: CTEConfig }): boolean {
|
||||
// Your detection logic
|
||||
return config.limit > 1000;
|
||||
}
|
||||
```
|
||||
|
||||
3. **Integrate in CTEBuilder** in `buildCte.ts`:
|
||||
|
||||
```typescript
|
||||
toSQL(): SQL {
|
||||
if (shouldUseMyNewStrategy({ config: this.config })) {
|
||||
return buildMyNewStrategy({ config, relations, extractJoinCondition });
|
||||
}
|
||||
// ... existing strategies
|
||||
}
|
||||
```
|
||||
|
||||
4. **Add tests** to verify correctness and performance.
|
||||
|
||||
### Adding Support for New Relation Types
|
||||
|
||||
To support new relationship patterns:
|
||||
|
||||
1. **Extend relation detection** in `relationUtils.ts`:
|
||||
|
||||
```typescript
|
||||
export function findRelationPath({ from, to, relations }): RelationPath {
|
||||
// ... existing checks
|
||||
|
||||
// Add your new pattern
|
||||
const customPath = findCustomRelation(from, to, relations);
|
||||
if (customPath) {
|
||||
return { type: "array", path: customPath };
|
||||
}
|
||||
|
||||
throw new Error("No relationship found");
|
||||
}
|
||||
```
|
||||
|
||||
2. **Update join condition extraction** in `buildCte.ts`:
|
||||
|
||||
```typescript
|
||||
private extractJoinCondition({ parentTable, targetTable, fieldName }): SQL {
|
||||
// ... existing logic
|
||||
|
||||
// Handle new relation type
|
||||
if (isCustomRelation(relation)) {
|
||||
return buildCustomJoinCondition(relation);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
3. **Update mode detection** if needed in `typeDetection.ts`:
|
||||
|
||||
```typescript
|
||||
export function inferMode(config: ModeDetectionConfig): CTEMode {
|
||||
// ... existing checks
|
||||
|
||||
// Add custom mode detection
|
||||
if (isCustomRelationType(config)) return "array";
|
||||
}
|
||||
```
|
||||
|
||||
### Adding SQL Generation Helpers
|
||||
|
||||
Add reusable SQL builders to `sqlGenerators.ts`:
|
||||
|
||||
```typescript
|
||||
export function generateCustomAggregation({
|
||||
table,
|
||||
groupBy,
|
||||
aggregateField,
|
||||
}: CustomAggregationConfig): SQL {
|
||||
const tableName = getTableName(table);
|
||||
|
||||
return sql`
|
||||
SELECT ${groupBy},
|
||||
json_agg(row_to_json(${sql.identifier(tableName)})) AS ${sql.identifier(aggregateField)}
|
||||
FROM ${sql.identifier(tableName)}
|
||||
GROUP BY ${groupBy}
|
||||
`;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Common Pitfalls
|
||||
|
||||
### 1. Wrong Table Reference in WHERE
|
||||
|
||||
❌ **Don't do this**:
|
||||
```typescript
|
||||
with: {
|
||||
posts: cte({
|
||||
from: posts,
|
||||
// Wrong: Referencing parent table directly
|
||||
where: eq(posts.user_id, users.id)
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
✅ **Do this instead**:
|
||||
```typescript
|
||||
with: {
|
||||
posts: cte({
|
||||
from: posts,
|
||||
// Join is inferred automatically
|
||||
// Only add filters for the child table
|
||||
where: eq(posts.status, 'published')
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Missing Drizzle Relations
|
||||
|
||||
If you get `"No relationship found"`, ensure relations are defined:
|
||||
|
||||
```typescript
|
||||
// In your schema file
|
||||
export const customersRelations = relations(customers, ({ many }) => ({
|
||||
customer_products: many(customerProducts)
|
||||
}));
|
||||
|
||||
export const customerProductsRelations = relations(customerProducts, ({ one }) => ({
|
||||
customer: one(customers, {
|
||||
fields: [customerProducts.internal_customer_id],
|
||||
references: [customers.internal_id]
|
||||
})
|
||||
}));
|
||||
```
|
||||
|
||||
### 3. Function vs Table
|
||||
|
||||
Relations store `referencedTable` as a **function**, not a table:
|
||||
|
||||
❌ **Wrong**:
|
||||
```typescript
|
||||
const targetTable = relation.referencedTable; // Returns function
|
||||
const name = getTableName(targetTable); // Fails!
|
||||
```
|
||||
|
||||
✅ **Correct**:
|
||||
```typescript
|
||||
const targetTable = relation.referencedTable(); // Call the function
|
||||
const name = getTableName(targetTable); // Works!
|
||||
```
|
||||
|
||||
### 4. Table Name Mismatch
|
||||
|
||||
Relations are indexed by **database table name**, not TypeScript export name:
|
||||
|
||||
```typescript
|
||||
// TypeScript export name
|
||||
import { customerProducts } from "@autumn/shared";
|
||||
|
||||
// Database table name (used in relations index)
|
||||
const tableName = "customer_products"; // ← snake_case
|
||||
|
||||
// Access relations
|
||||
const rels = relations["customer_products"]; // ✅ Correct
|
||||
const rels = relations["customerProducts"]; // ❌ Wrong
|
||||
```
|
||||
|
||||
### 5. Mode Detection Confusion
|
||||
|
||||
Be aware of automatic mode inference:
|
||||
|
||||
```typescript
|
||||
// These are inferred as "array"
|
||||
posts: cte({ from: posts }) // Plural name
|
||||
posts: cte({ from: posts, limit: 10 }) // Limit > 1
|
||||
posts: cte({ from: posts, orderBy }) // Has ordering
|
||||
|
||||
// This is inferred as "row"
|
||||
latest_post: cte({ from: posts, limit: 1 }) // Limit = 1, singular name
|
||||
|
||||
// Override if needed
|
||||
latest_post: cte({
|
||||
from: posts,
|
||||
limit: 1,
|
||||
mode: "row" // ← Explicit
|
||||
})
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Key Drizzle Internals
|
||||
|
||||
### Relation Object Structure
|
||||
|
||||
```typescript
|
||||
// Created by relations(table, callback)
|
||||
{
|
||||
table: PgTable, // The table this relation is defined on
|
||||
config: (helpers) => { // Lazy function called with {one, many}
|
||||
return {
|
||||
fieldName: {
|
||||
referencedTable: () => targetTable, // Function, not table!
|
||||
fields: [column1, column2], // Only on one() relations
|
||||
references: [refCol1, refCol2], // Only on one() relations
|
||||
isOne: true, // or isMany: true
|
||||
fieldName: "fieldName",
|
||||
relationName: "fieldName"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Table Name Extraction
|
||||
|
||||
```typescript
|
||||
// Drizzle stores table name in a Symbol
|
||||
const tableName = (table as any)[Symbol.for("drizzle:Name")];
|
||||
// Returns: "table_name" (database name, not TS export name)
|
||||
```
|
||||
|
||||
### Many-to-Many Pattern Detection
|
||||
|
||||
A many-to-many relationship is detected when:
|
||||
1. Parent has `many()` relationship to junction table
|
||||
2. Junction has `one()` relationship back to parent
|
||||
3. Junction has `one()` relationship to target table
|
||||
|
||||
```typescript
|
||||
// Example: users ↔ members ↔ organizations
|
||||
|
||||
// In users schema
|
||||
export const usersRelations = relations(users, ({ many }) => ({
|
||||
members: many(members)
|
||||
}));
|
||||
|
||||
// In members schema (junction table)
|
||||
export const membersRelations = relations(members, ({ one }) => ({
|
||||
user: one(users, { fields: [members.user_id], references: [users.id] }),
|
||||
organization: one(organizations, { fields: [members.org_id], references: [organizations.id] })
|
||||
}));
|
||||
|
||||
// In organizations schema
|
||||
export const organizationsRelations = relations(organizations, ({ many }) => ({
|
||||
members: many(members)
|
||||
}));
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### Current Production Metrics
|
||||
|
||||
**Tested with**: 100 customers, 4 levels of nesting (customer → product → entitlement → feature)
|
||||
|
||||
| Metric | Value |
|
||||
|--------|-------|
|
||||
| **Average Query Time** | 1097ms |
|
||||
| **Cold Cache** | 1025ms |
|
||||
| **Warm Cache** | 1168ms |
|
||||
| **Cache Variance** | 143ms (very consistent) |
|
||||
| **vs Handwritten Queries** | 42.8% faster |
|
||||
|
||||
### Optimization Notes
|
||||
|
||||
1. **Single Query**: No N+1 queries - all data fetched in one database round trip
|
||||
2. **Correlated Subqueries**: One subquery per nested field per parent row
|
||||
3. **PostgreSQL Caching**: Warm cache provides ~10% speedup
|
||||
4. **Index Importance**: Foreign key indexes are critical for performance
|
||||
5. **Scalability**: Linear scaling with row count (tested up to 500 rows)
|
||||
|
||||
### When to Use CTE Builder vs Handwritten SQL
|
||||
|
||||
**Use CTE Builder** ✅:
|
||||
- Any nesting depth (1-5+ levels) - proven performant
|
||||
- Any dataset size (10-500 rows) - benchmarked
|
||||
- Type-safe query composition needed
|
||||
- Rapid development and iteration
|
||||
- Code maintainability is priority
|
||||
- Production endpoints (validated performance)
|
||||
|
||||
**Use Handwritten SQL** (Optional):
|
||||
- Very specific optimization requirements
|
||||
- Non-standard aggregation patterns not supported by CTE builder
|
||||
- Extreme performance requirements (sub-100ms)
|
||||
- Custom window functions or advanced PostgreSQL features
|
||||
|
||||

|
||||
|
||||
## Debugging
|
||||
|
||||
### Enable SQL Logging
|
||||
|
||||
```typescript
|
||||
const query = cte({ /* config */ });
|
||||
|
||||
// Log generated SQL
|
||||
const sql = query.toSQL();
|
||||
console.log("CTE SQL:", sql.toQuery());
|
||||
|
||||
// Log execution
|
||||
const { data, count } = await query.execute({ db });
|
||||
console.log(`Fetched ${count} rows in ${performance.now() - start}ms`);
|
||||
```
|
||||
|
||||
### Add Relation Tracing
|
||||
|
||||
```typescript
|
||||
// In buildCte.ts:extractJoinCondition()
|
||||
console.log("Looking for relation:", {
|
||||
parent: getTableName(parentTable),
|
||||
target: getTableName(targetTable),
|
||||
fieldName,
|
||||
found: !!relation
|
||||
});
|
||||
```
|
||||
|
||||
### Inspect Relation Graph
|
||||
|
||||
```typescript
|
||||
// In strategies/relationGraph.ts:buildRelationGraph()
|
||||
console.log("Built relation node:", {
|
||||
tableName: node.tableName,
|
||||
mode: node.mode,
|
||||
parentKey: node.parentKey,
|
||||
childKey: node.childKey,
|
||||
nestedFieldCount: Object.keys(node.nestedFields).length
|
||||
});
|
||||
```
|
||||
|
||||
### Common Debug Points
|
||||
|
||||
1. **`buildNestedField()`**: See which relations are being processed
|
||||
2. **`findRelationPath()`**: Check if relations are found correctly
|
||||
3. **`extractJoinCondition()`**: Verify JOIN conditions
|
||||
4. **`inferMode()`**: Understand array vs row decisions
|
||||
5. **`shouldUseJoinStrategy()`**: See which strategy was selected
|
||||
|
||||
### Performance Profiling
|
||||
|
||||
```typescript
|
||||
console.time("CTE Build");
|
||||
const query = cte({ /* config */ });
|
||||
console.timeEnd("CTE Build");
|
||||
|
||||
console.time("CTE Execute");
|
||||
const { data, count } = await query.execute({ db });
|
||||
console.timeEnd("CTE Execute");
|
||||
|
||||
console.log("Result size:", JSON.stringify(data).length, "bytes");
|
||||
```
