fraiseql-confiture 0.8.4

PostgreSQL schema evolution with built-in multi-agent coordination 🍓

Confiture 🍓

PostgreSQL migrations with multi-agent coordination, timestamp-based versioning, and 4 flexible strategies

Build fresh databases in <1 second. Zero-downtime migrations. Multi-agent conflict detection. No merge conflicts (timestamp-based versioning). Production data sync with PII anonymization.

---

Why Confiture?

Problem: Traditional migration tools replay every migration on every build (slow, brittle, maintains technical debt).

Solution: DDL files are the single source of truth. Just execute your schema once. Fresh databases in <1 second.

Multi-Agent Safe: Automatic conflict detection prevents teams and agents from stepping on each other.

Quick Start

Installation

pip install fraiseql-confiture

# Recommended: include pglast for large-schema support
# (uses PostgreSQL's own C parser — no token limits, handles schemas with bulk seed data)
pip install "fraiseql-confiture[ast]"

Basic Usage

# Initialize project
confiture init

# Write schema DDL files
vim db/schema/10_tables/users.sql

# Build database (<1 second)
confiture build --env local

# Generate and apply migrations
confiture migrate generate --name "add_bio"
confiture migrate up

Team Workflow (Multi-Agent)

# Register intention before making changes
confiture coordinate register --agent-id alice --tables-affected users

# Check for conflicts (by other agent)
confiture coordinate check --agent-id bob --tables-affected users
# ⚠️ Conflict: alice is working on 'users'

# Complete when done
confiture coordinate complete --intent-id int_abc123

Core Features

🛠️ Four Migration Strategies

Strategy	Use Case	Command
Build from DDL	Fresh DBs, testing	confiture build --env local
Incremental	Existing databases	confiture migrate up
Production Sync	Copy prod data (with anonymization)	confiture sync --from production --anonymize users.email
Zero-Downtime	Complex migrations via FDW	confiture migrate schema-to-schema

🤝 Multi-Agent Coordination

• ✅ Automatic conflict detection
• ✅ Intent registration and tracking
• ✅ JSON output for CI/CD
• ✅ <10ms per operation

🌱 Seed Data Management

• ✅ Sequential execution (solves PostgreSQL parser limits on 650+ row files)
• ✅ Per-file savepoint isolation for error recovery
• ✅ Continue-on-error mode (skip failed files)
• ✅ Prep-seed validation (5-level orchestrator)
• ✅ 5-level validation (static → full execution)
• ✅ Catch NULL FKs before production
• ✅ Pre-commit safe (Levels 1-3)
• ✅ Database validation with SAVEPOINT safety

🔍 Git-Aware Validation

• ✅ Detect schema drift vs. main branch
• ✅ Enforce migrations for DDL changes
• ✅ Pre-commit hook support

🔧 Developer Experience

• ✅ Dry-run mode (analyze before applying)
• ✅ Migration hooks (pre/post)
• ✅ Schema linting
• ✅ PII anonymization
• ✅ Optional Rust extension
• ✅ Python 3.11, 3.12, 3.13
