Evaluate ObjectQL → @objectstack/runtime migration: comprehensive planning, architecture & protocol improvements

[Copilot]

Objective

Assess work required to reposition ObjectQL from standalone ORM to query plugin ecosystem on @objectstack/runtime base framework.

Current State

ObjectQL v3.x imports @objectstack types but doesn't use the runtime kernel. Own lifecycle, metadata registry, and driver orchestration duplicate @objectstack/runtime functionality.

Analysis Delivered

1. Architecture Design

PLUGIN_ARCHITECTURE.md (17KB)

• 5 plugin types: Driver, QueryProcessor, Repository, Feature, Optimizer
• Full TypeScript interfaces with composition patterns
• Reference implementation examples

2. Migration Mapping

FEATURE_MIGRATION_MATRIX.md (14KB)

• 60+ features analyzed: 42% → runtime, 47% → plugins, 11% → keep
• Priority (P0-P3) and effort estimates per feature
• 6 migration waves with dependency chains

3. Package Restructuring

PACKAGE_RESTRUCTURING.md (15KB)

• 15+ packages to migrate, 6+ new plugins to create
• Publishing strategy: Alpha → Beta → RC → GA
• @objectql/legacy compatibility layer for v3.x API

4. Implementation Plan

IMPLEMENTATION_ROADMAP.md (16KB)

• Week-by-week breakdown (22 weeks total)
• 626 engineering hours estimated
• Quality gates and contingency planning

5. Strategic Overview

MIGRATION_STRATEGY.md (15KB)

• 12 phases with risk assessment
• 5 technical decisions (metadata ownership, plugin loading, AST standard)
• Success metrics: <10% overhead, 90%+ coverage, zero critical CVEs

6. Protocol Improvements Plan (NEW)

PROTOCOL_IMPROVEMENTS.md (32KB, bilingual 🇨🇳🇺🇸)

• Comprehensive protocol analysis (协议改进计划)
• 5 major protocol improvements identified:
  • QueryAST standardization with aggregation support
  • DriverInterface enhancement (errors, transactions, batching, streaming)
  • Plugin communication protocol (event bus, data sharing)
  • Metadata protocol versioning (auto-migration, schema registry)
  • API protocol standardization (REST/GraphQL unification)
• 13-week detailed work plan (520 hours)
• Team: 2 senior engineers
• Budget: ~$64,400
• Success metrics: 100% protocol consistency, >90% test coverage, <5% overhead

Key Metrics

Features:     60+ analyzed → 25 to runtime, 28 to plugins, 7 stay
Scope:        15 packages, 8 drivers, 6 new plugins
Timeline:     22 weeks overall migration (626 eng hours)
              + 13 weeks protocol improvements (520 eng hours)
              = 35 weeks combined (can run in parallel)
Team:         2-3 engineers recommended
Budget:       $60k-$80k overall + $64k protocol = $124k-$144k total
Documents:    8 comprehensive planning documents (144KB, 4,900+ lines)

Architecture Transformation

// Before: Monolithic
const app = new ObjectQL({ datasources: { default: driver } });

// After: Plugin composition
const runtime = createRuntime({
  plugins: [
    sqlDriverPlugin({ connection: '...' }),
    queryValidationPlugin(),
    advancedRepositoryPlugin()
  ]
});

Critical Paths

1. Runtime integration (weeks 1-4) → driver plugins (weeks 5-6)
2. Query validation + repository plugins (weeks 7-10) → feature plugins (weeks 11-18)
3. Tools update (weeks 19-20) → testing/release (weeks 21-22)
4. Protocol improvements (weeks 1-13, parallel track)

Recommendation

Proceed. Migration is feasible with documented risks and mitigation strategies. Backward compatibility maintained via wrapper package through v4.x. Protocol improvements can run in parallel with core migration work.

Original prompt

评估现有代码全面迁移到@objectstack/runtime 新架构的工作清单，原则上这个仓库只是一个插件仓库，在objectstack的基础框架中开发插件扩展查询相关的功能

   • 元数据版本化（Weeks 8-9）
   • API 协议标准化（Weeks 10-11）

2. 详细工作计划：

   • 每周具体任务分解
   • 资源和角色分配
   • 风险评估和缓解措施
   • 质量保证策略

3. 中英双语：完整的中英文对照说明

关键成果：
