🧭 Chore Summary — Enable AI Alliance Analytics Stack Integration

Integrate MCP Gateway into the AI Alliance analytics stack following their established github_analytics table schema for automated metrics collection, S3 storage, and Grafana visualization. This ensures data compatibility with the existing AI Alliance analytics infrastructure and table definitions.

🧱 Areas Affected

• GitHub Actions — daily metrics collection workflow following AI Alliance pattern
• Python scripts — metrics collection matching exact github_analytics schema
• Docker container — containerized metrics collection for AI Alliance scheduling
• Repository secrets — AWS S3 and GitHub token configuration
• S3 data pipeline — Parquet storage with correct partitioning: service=github/repository=IBM_mcp-context-forge/date=YYYY-MM-DD/
• Schema compliance — Data format matching AI Alliance aialliance.github_analytics table

⚙️ Context / Rationale

Following the AI Alliance github_analytics table schema, we need to collect MCP Gateway metrics in the exact format expected by their analytics infrastructure:

🔍 Schema Compliance Requirements:

• Match exact column names from aialliance.github_analytics table
• Provide both cumulative metrics (stars, forks_total) and period-based deltas (forks_new_last_period)
• Include traffic metrics with daily totals and unique counts
• Support partitioning by service=github/repository=<name>/date=<YYYY-MM-DD>/
• Generate Parquet files compatible with MSCK REPAIR TABLE operations

📊 Required Metrics (per AI Alliance schema):

• Repository basics: stars, watchers, forks_total, open_issues_total, network_count, size_kb
• Metadata: language, created_at_utc, pushed_at_utc, feature flags (has_issues, has_wiki, etc.)
• Community: contributors_count_total, releases_count_total
• Activity periods: issues/PRs opened/closed/merged in last period
• Traffic: daily views/clones (total and unique), top referrers

Phase 3: Updated Documentation

• 3.1 Updated integration guide docs/analytics/ai-alliance-integration.md

  # AI Alliance Analytics Integration
  
  ## Schema Compliance
  
  MCP Gateway metrics are collected to match the exact `aialliance.github_analytics` table schema:
  
  ### Required Columns
  
  | Column | Type | Description |
  |--------|------|-------------|
  | `timestamp_utc` | timestamp | Collection timestamp |
  | `repository_name` | string | Full repository name (e.g., IBM/mcp-context-forge) |
  | `stars` | int | Current star count |
  | `watchers` | int | Current watcher count |
  | `forks_total` | int | Total forks count |
  | `open_issues_total` | int | Current open issues |
  | `traffic_views_last_day_total` | int | Daily view count |
  | `traffic_views_last_day_unique` | int | Daily unique visitors |
  | `issues_opened_last_period` | int | Issues opened in last 7 days |
  | `prs_merged_last_period` | int | PRs merged in last 7 days |
  | *...and 30+ additional columns* | | |
  
  ### Partitioning Structure
  
  Data is stored in S3 with the following partitioning:

  s3://aialliance-analytics-bucket/
  └── service=github/
  └── repository=IBM_mcp-context-forge/
  └── date=2024-01-15/
  └── blob.parquet

  
  ## Querying Data
  
  Once uploaded, data can be queried using:
  
  ```sql
  -- Refresh partitions first
  MSCK REPAIR TABLE aialliance.github_analytics;
  
  -- Query MCP Gateway metrics
  SELECT 
      date,
      stars,
      forks_total,
      issues_opened_last_period,
      prs_merged_last_period
  FROM aialliance.github_analytics 
  WHERE repository = 'IBM_mcp-context-forge'
  ORDER BY date DESC;
  

  Schema Validation

  To validate data format before upload:

  python src/github/validate_schema.py temp_data_github/IBM_mcp-context-forge_2024-01-15.parquet

📦 Updated Deliverables

1. Schema-compliant script: src/github/src/github_analytics.py matching exact AI Alliance table structure
2. Schema validation: src/github/validate_schema.py for data format verification
3. Correct partitioning: S3 storage following service=github/repository=<name>/date=<date>/ pattern
4. Period calculations: Proper delta calculations for period-based metrics
5. Traffic integration: GitHub traffic API data collection
6. Array handling: Top referrers as string arrays per schema requirements

🎯 Expected Outcomes

Full Schema Compliance:

• All 40+ columns matching aialliance.github_analytics table exactly
• Correct data types (timestamps, integers, booleans, string arrays)
• Proper partitioning for efficient querying

Analytics Integration:

• Data immediately queryable via AI Alliance Athena/Presto
• Compatible with existing AI Alliance Grafana dashboards
• Support for MSCK REPAIR TABLE operations

Period-Based Insights:

• Weekly delta calculations for growth tracking
• Activity metrics showing community engagement trends
• Traffic patterns and referrer analysis

🧩 Additional Notes

• Schema typos: Works around schema typos like "releases_count_tota"
• Period calculations: Implements 7-day rolling windows for delta metrics
• Traffic API: Utilizes GitHub traffic API for view/clone statistics
• Array fields: Handles referrer data as string arrays per schema
• Partitioning: Ensures proper Hive-style partitioning for AI Alliance queries
• Validation: Built-in schema validation prevents data format issues
