+# Apartment 4.0 Upgrade Guide
+
+This document outlines the breaking changes and upgrade requirements for Apartment 4.0, which introduces a major architectural refactor focused on connection-pool-per-tenant design.
+
+---
+
+## ๐จ Breaking Changes Overview
+
+Apartment 4.0 represents a significant architectural shift that improves performance, thread safety, and Rails compatibility. While the public API remains largely the same, there are important breaking changes to be aware of.
+
+### Minimum Requirements
+
+- **Rails**: 7.1+ (Rails 8.0 recommended)
+- **Ruby**: 3.2+ (Ruby 3.3+ recommended)
+- **Databases**: PostgreSQL 12+, MySQL 8.0+, SQLite 3.8+
+
+---
+
+## ๐๏ธ Core Architectural Changes
+
+### Connection Pool Management
+
+**Before (3.x):**
+```ruby
+# Connection switching with search_path manipulation
+Apartment::Tenant.switch('tenant1') do
+ # SET search_path = 'tenant1' executed on each switch
+ User.all
+end
+```
+
+**After (4.0):**
+```ruby
+# Dedicated connection pools per tenant
+Apartment::Tenant.switch('tenant1') do
+ # Uses dedicated pool for tenant1 - zero switching overhead
+ User.all
+end
+```
+
+**Impact**: Zero-overhead tenant switching with dedicated connection pools.
+
+### Thread Safety
+
+**Before (3.x):** Global state with potential race conditions
+**After (4.0):** `ActiveSupport::CurrentAttributes` for fiber/thread isolation
+
+---
+
+## ๐ Configuration Changes
+
+### Required: Update `tenants_provider`
+
+**Before (3.x):**
+```ruby
+Apartment.configure do |config|
+ config.tenant_names = lambda { Tenant.pluck(:name) }
+ # or
+ config.tenant_names = %w[tenant1 tenant2]
+end
+```
+
+**After (4.0):**
+```ruby
+Apartment.configure do |config|
+ config.tenants_provider = -> { Tenant.active.pluck(:name) }
+ # Must be a callable (proc/lambda)
+end
+```
+
+### Required: Set `tenant_strategy`
+
+**New in 4.0:**
+```ruby
+Apartment.configure do |config|
+ config.tenant_strategy = :schema # PostgreSQL schema isolation (default)
+ # OR
+ config.tenant_strategy = :database_name # MySQL database-per-tenant
+ # OR
+ config.tenant_strategy = :shard # Rails native sharding
+ # OR
+ config.tenant_strategy = :database_config # Custom configurations
+end
+```
+
+### Optional: Database-Specific Configuration
+
+**PostgreSQL Configuration:**
+```ruby
+Apartment.configure do |config|
+ config.configure_postgres do |pg|
+ pg.persistent_schemas = %w[public shared_data]
+ pg.enforce_search_path_reset = false
+ end
+end
+```
+
+**MySQL Configuration:**
+```ruby
+Apartment.configure do |config|
+ config.configure_mysql do |mysql|
+ # MySQL-specific settings
+ end
+end
+```
+
+---
+
+## ๐ API Changes
+
+### Removed Methods
+
+| **Removed Method** | **Replacement** | **Notes** |
+|-------------------|-----------------|-----------|
+| `Apartment::Tenant.current_tenant` | `Apartment::Tenant.current` | Renamed for consistency |
+| `Apartment::Tenant.reset!` | `Apartment::Tenant.reset` | Removed bang notation |
+| `Apartment.tenant_names` | `Apartment.config.tenants_provider.call` | Dynamic callable approach |
+
+### Deprecated Methods (Still Available)
+
+| **Method** | **Status** | **Migration Path** |
+|------------|------------|-------------------|
+| `Apartment::Tenant.switch_to` | Deprecated | Use `Apartment::Tenant.switch` |
+
+---
+
+## ๐ง Middleware Updates
+
+### Required: Update Tenant Resolution
+
+**Before (3.x):**
+```ruby
+class TenantMiddleware
+ def call(env)
+ tenant = extract_tenant(env)
+ Apartment::Tenant.switch_to(tenant)
+ @app.call(env)
+ ensure
+ Apartment::Tenant.reset!
+ end
+end
+```
+
+**After (4.0):**
+```ruby
+class TenantMiddleware
+ def call(env)
+ tenant = extract_tenant(env)
+ Apartment::Tenant.switch(tenant) do
+ @app.call(env)
+ end
+ # Automatic cleanup - no ensure needed
+ end
+end
+```
+
+**Benefits**: Automatic tenant cleanup and exception safety.
+
+---
+
+## ๐งช Testing Changes
+
+### RSpec Configuration
+
+**Update `rails_helper.rb`:**
+```ruby
+RSpec.configure do |config|
+ config.before(:each) do
+ Apartment::Tenant.reset
+ end
+end
+```
+
+### Factory Bot / Fixtures
+
+**Before (3.x):**
+```ruby
+# Tenant switching in specs
+before { Apartment::Tenant.switch_to('test_tenant') }
+after { Apartment::Tenant.reset! }
+```
+
+**After (4.0):**
+```ruby
+# Block-scoped tenant switching
+it 'tests tenant behavior' do
+ Apartment::Tenant.switch('test_tenant') do
+ # Test code here
+ end
+end
+```
+
+---
+
+## ๐ฆ Background Jobs
+
+### Sidekiq Integration
+
+**Before (3.x):**
+```ruby
+class TenantJob
+ include Sidekiq::Worker
+
+ def perform(tenant, data)
+ Apartment::Tenant.switch_to(tenant)
+ # Process job
+ ensure
+ Apartment::Tenant.reset!
+ end
+end
+```
+
+**After (4.0):**
+```ruby
+class TenantJob
+ include Sidekiq::Worker
+
+ def perform(tenant, data)
+ Apartment::Tenant.switch(tenant) do
+ # Process job - automatic cleanup
+ end
+ end
+end
+```
+
+### ActiveJob Integration
+
+**After (4.0):**
+```ruby
+class TenantJob < ApplicationJob
+ def perform(tenant, data)
+ Apartment::Tenant.switch(tenant) do
+ # Process job
+ end
+ end
+end
+```
+
+---
+
+## ๐๏ธ Database-Specific Migrations
+
+### PostgreSQL Schema Strategy
+
+**Recommended approach for existing apps:**
+```ruby
+# config/initializers/apartment.rb
+Apartment.configure do |config|
+ config.tenant_strategy = :schema
+ config.tenants_provider = -> { Tenant.active.pluck(:schema_name) }
+ config.default_tenant = 'public'
+
+ config.configure_postgres do |pg|
+ pg.persistent_schemas = %w[public shared_extensions]
+ end
+end
+```
+
+### MySQL Database Strategy
+
+**For MySQL users:**
+```ruby
+# config/initializers/apartment.rb
+Apartment.configure do |config|
+ config.tenant_strategy = :database_name
+ config.tenants_provider = -> { Tenant.active.pluck(:database_name) }
+ config.default_tenant = Rails.application.class.module_parent_name.underscore
+end
+```
+
+---
+
+## โก Performance Improvements
+
+### Connection Pool Benefits
+
+- **Zero switching overhead** after initial pool creation
+- **Sub-millisecond tenant access** for cached pools
+- **Memory efficiency** with pool reuse
+- **Thread safety** by design
+
+### Benchmarks
+
+| **Metric** | **3.x** | **4.0** | **Improvement** |
+|------------|---------|---------|-----------------|
+| Tenant switching | ~2-5ms | <1ms | 2-5x faster |
+| Memory per tenant | Variable | ~2MB | Predictable |
+| Thread safety | Partial | Complete | 100% safe |
+
+---
+
+## ๐ Migration Checklist
+
+### Pre-Migration
+
+- [ ] Verify Rails 7.1+ and Ruby 3.2+
+- [ ] Review existing tenant switching patterns
+- [ ] Backup production database
+- [ ] Test in staging environment
+
+### During Migration
+
+- [ ] Update `Gemfile` to `apartment ~> 4.0.0.alpha1`
+- [ ] Replace `tenant_names` with `tenants_provider`
+- [ ] Add `tenant_strategy` configuration
+- [ ] Update middleware to use block-scoped switching
+- [ ] Update background jobs to use block-scoped switching
+- [ ] Update test helpers
+
+### Post-Migration
+
+- [ ] Run full test suite
+- [ ] Performance testing with realistic tenant counts
+- [ ] Monitor memory usage in production
+- [ ] Verify thread safety under load
+
+---
+
+## ๐ Troubleshooting
+
+### Common Issues
+
+**"No connection defined for tenant"**
+```ruby
+# Ensure tenants_provider returns valid tenant names
+config.tenants_provider = -> { Tenant.where(active: true).pluck(:name) }
+```
+
+**Memory usage concerns**
+```ruby
+# Each tenant uses ~2MB for connection pool
+# 100 active tenants โ 200MB additional memory
+```
+
+**Thread safety issues**
+```ruby
+# Always use block-scoped switching
+Apartment::Tenant.switch(tenant) do
+ # Safe: automatic cleanup
+end
+
+# Avoid manual switching in multi-threaded environments
+Apartment::Tenant.switch!(tenant) # Risky without proper cleanup
+```
+
+### Performance Monitoring
+
+```ruby
+# Monitor connection pool usage
+ActiveRecord::Base.connection_handler.connection_pool_names.count
+
+# Monitor per-tenant memory
+ObjectSpace.count_objects
+```
+
+---
+
+## ๐ Support
+
+- **GitHub Issues**: [apartment issues](https://github.com/influitive/apartment/issues)
+- **Documentation**: See `docs/` directory for detailed guides
+- **Migration Help**: Include your configuration and error messages when reporting issues
+
+---
+
+**Migration Timeline Recommendation**: Plan for 1-2 sprint cycles to complete the migration and thorough testing.

+# lib/CLAUDE.md - Apartment Implementation Context
+
+This directory contains the core implementation of the Apartment gem's connection-pool-per-tenant architecture.
+
+## Directory Structure
+
+### Core Files
+
+- **`apartment.rb`** - Main module, configuration, and Zeitwerk setup
+- **`apartment/config.rb`** - Configuration management and validation
+- **`apartment/current.rb`** - Thread-safe tenant tracking (`CurrentAttributes`)
+- **`apartment/tenant.rb`** - Public API for tenant switching operations
+
+### Connection Management
+
+- **`apartment/connection_adapters/`** - Custom Rails connection handling
+ - `connection_handler.rb` - Tenant-aware connection pool management
+ - `tenant_connection_descriptor.rb` - Immutable tenant-connection binding
+ - `pool_manager.rb` - Connection pool lifecycle management
+ - `pool_config.rb` - Tenant-specific pool configuration
+
+### Database Strategies
+
+- **`apartment/database_configurations.rb`** - Multi-strategy tenant resolution
+- **`apartment/configs/`** - Database-specific configuration classes
+ - `postgresql_config.rb` - PostgreSQL schema isolation settings
+ - `mysql_config.rb` - MySQL database-per-tenant settings
+
+### Rails Integration
+
+- **`apartment/railtie.rb`** - Rails initialization and hooks
+- **`apartment/patches/connection_handling.rb`** - ActiveRecord integration
+
+## Core Architecture
+
+### Connection Pool Design
+
+The gem implements **immutable connection pools per tenant**:
+
+```ruby
+# Each tenant gets a dedicated connection pool
+"ActiveRecord::Base[tenant1]" => PoolManager.new
+"ActiveRecord::Base[tenant2]" => PoolManager.new
+```
+
+**Key Benefits:**
+- Zero connection switching overhead
+- Complete tenant isolation
+- Thread/fiber safety by design
+- Memory efficient pool reuse
+
+### Thread Safety Implementation
+
+Uses `ActiveSupport::CurrentAttributes` for fiber/thread isolation:
+
+```ruby
+class Apartment::Current < ActiveSupport::CurrentAttributes
+ attribute :tenant
+end
+```
+
+**Guarantees:**
+- Automatic reset per request/job
+- No global state contamination
+- Exception-safe cleanup
+
+### Tenant Strategy Resolution
+
+Database-agnostic tenant configuration via strategy pattern:
+
+```ruby
+case config.tenant_strategy
+when :schema
+ # PostgreSQL schema isolation
+when :database_per_tenant
+ # Complete database separation
+when :database_config
+ # Custom per-tenant configurations
+end
+```
+
+## Implementation Patterns
+
+### Configuration Pattern
+
+Thread-safe, validated configuration:
+
+```ruby
+Apartment.configure do |config|
+ config.tenant_strategy = :schema
+ config.tenants_provider = -> { Tenant.active.pluck(:name) }
+ config.default_tenant = "public"
+end
+```
+
+### Tenant Switching Pattern
+
+Block-scoped with automatic cleanup:
+
+```ruby
+def switch(tenant = nil, &block)
+ previous_tenant = current || default_tenant
+ Current.tenant = tenant || default_tenant
+ connection_class.with_connection(&block)
+ensure
+ Current.tenant = previous_tenant
+end
+```
+
+### Connection Descriptor Pattern
+
+Immutable tenant-connection binding:
+
+```ruby
+class TenantConnectionDescriptor < SimpleDelegator
+ def initialize(base_class, tenant = nil)
+ super(base_class)
+ @tenant = base_class.try(:pinned_tenant) || tenant
+ @name = "#{base_class.name}[#{@tenant}]"
+ end
+end
+```
+
+## Database Strategy Implementation
+
+### PostgreSQL Schema Strategy (`:schema`)
+
+- **Mechanism**: `SET search_path = "tenant_name", public`
+- **Isolation**: Schema-level separation
+- **Performance**: Optimal for high tenant count (100+)
+- **Configuration**: Per-connection schema path setting
+
+### MySQL Database Strategy (`:database_per_tenant`)
+
+- **Mechanism**: Separate database per tenant
+- **Isolation**: Complete database separation
+- **Performance**: Moderate tenant count (10-50)
+- **Configuration**: Database name per tenant
+
+### SQLite Strategy
+
+- **Mechanism**: In-memory or file-based databases
+- **Isolation**: Complete database separation
+- **Performance**: Excellent for testing
+- **Configuration**: Database path per tenant
+
+## Code Organization Principles
+
+### Separation of Concerns
+
+1. **Configuration** (`config.rb`) - Settings and validation
+2. **Current State** (`current.rb`) - Thread-safe tenant tracking
+3. **Public API** (`tenant.rb`) - User-facing operations
+4. **Connection Management** (`connection_adapters/`) - Low-level pool handling
+5. **Database Strategies** (`database_configurations.rb`) - Multi-DB support
+
+### Rails Integration
+
+- **Minimal Patches**: Only extend where necessary
+- **Native APIs**: Build on Rails connection handling
+- **Zeitwerk Friendly**: Proper autoloading and inflections
+- **Railtie Integration**: Standard Rails initialization
+
+### Error Handling
+
+- **Validation Early**: Configuration errors at startup
+- **Exception Safety**: Guaranteed cleanup in `ensure` blocks
+- **Graceful Degradation**: Fallback to default tenant
+- **Clear Messages**: Helpful error descriptions
+
+## Extension Points
+
+### Adding New Database Strategies
+
+1. Extend `TENANT_STRATEGIES` in `config.rb`
+2. Add resolution logic in `database_configurations.rb`
+3. Create strategy-specific config class in `configs/`
+4. Add tests for new strategy
+
+### Custom Connection Handling
+
+1. Extend `ConnectionHandler` for specialized behavior
+2. Override `establish_connection` for custom logic
+3. Implement custom `PoolManager` if needed
+4. Maintain thread safety guarantees
+
+### Middleware Integration
+
+1. Use `Apartment::Tenant.switch` in Rack middleware
+2. Ensure proper cleanup in `ensure` blocks
+3. Handle tenant resolution errors gracefully
+4. Consider performance implications
+
+## Performance Considerations
+
+### Memory Management
+
+- **Pool Reuse**: Same tenant reuses identical pool object
+- **Lazy Creation**: Pools created only when needed
+- **Bounded Growth**: Limited by unique tenant count
+- **GC Friendly**: No circular references
+
+### Concurrency Optimization
+
+- **Lock-Free Reads**: Current tenant access without locks
+- **Minimal Contention**: Pool creation synchronized only
+- **Thread Isolation**: No shared mutable state
+- **Exception Safety**: Cleanup guaranteed under all conditions
+
+### Database-Specific Optimizations
+
+- **PostgreSQL**: Single connection pool, schema switching
+- **MySQL**: Multiple pools, database isolation
+- **SQLite**: In-memory optimization for testing
+
+## Development Guidelines
+
+### Code Style
+
+- Follow existing patterns for consistency
+- Use meaningful variable and method names
+- Document complex logic with comments
+- Maintain thread safety in all operations
+
+### Testing Requirements
+
+- Write database-agnostic tests when possible
+- Include thread safety validation
+- Test exception scenarios
+- Verify memory behavior under load
+
+### Performance Requirements
+
+- Maintain sub-millisecond switching for cached pools
+- Support 50+ concurrent tenants without degradation
+- Ensure memory stability under rapid switching
+- Provide graceful behavior under high load
