Metabase BI Implementation Plan

Status: 🟢 Deployed (Phase 1, 2, 3 & 4 Complete, Phase 5 Ready) Last Updated: 2025-01-22 Owner: Engineering Team

Overview​

This document tracks the implementation of Metabase Business Intelligence (BI) integration for the FlowPOS multi-tenant POS system across staging and production environments.

Architecture Summary​

  • Single Metabase instance per environment (staging/production)
  • Two Cloud SQL connections per Metabase instance:
    1. Metabase Metadata DB: Separate small instance for Metabase internal data
    2. App Database: Existing POS database for analytics queries
  • Multi-tenant isolation: Using locked business_id parameters in embedded dashboards
  • Deployment: Cloud Run with autoscaling
  • Secrets Management: GitHub Secrets (for GitHub Actions), Doppler (for local development)

Cloud SQL Connection Architecture (socat Approach)​

Why socat? Metabase's PostgreSQL JDBC driver doesn't natively support Cloud SQL Unix sockets. The socat approach bridges this gap by forwarding TCP connections to Unix sockets.

How it works:

  1. Cloud Run's Cloud SQL Proxy (via --add-cloudsql-instances):

    • Provides Unix sockets at /cloudsql/PROJECT:REGION:INSTANCE/.s.PGSQL.5432
    • No VPC connector needed (Cloud Run handles this internally)
  2. socat forwarding (configured in Dockerfile startup script):

    • Listens on 127.0.0.1:5432 (metadata DB) and 127.0.0.1:5433 (app DB)
    • Forwards TCP connections to the corresponding Unix sockets
    • Runs as background process before Metabase starts
  3. Metabase connection:

    • Connects via standard PostgreSQL TCP to 127.0.0.1:5432 (metadata) or 127.0.0.1:5433 (app)
    • No special JDBC drivers or configuration needed

Benefits:

  • ✅ Works with standard PostgreSQL JDBC driver
  • ✅ No VPC connector required
  • ✅ Simpler than JDBC Socket Factory approach
  • ✅ Automatic socket availability detection
  • ✅ Graceful error handling if sockets aren't ready

Environments​

EnvironmentGCP ProjectCloud SQL Instance (Consolidated)Region

Productionbarto-prodmetabase-db-production ✅ (hosts both app DB flowpos_production and metadata DB metabase)us-central1

Note: Instances have been consolidated to reduce infrastructure costs. Each Metabase instance now hosts both the application database and Metabase metadata database.

    • Accepts environment (staging/production) as parameter
    • Reads connection details from GitHub Secrets or Doppler (for local dev)
    • Creates connection via Metabase API
  • Alternative: Use Terraform for Metabase configuration:

    • Create Terraform module for Metabase setup
    • Automate database connection configuration
    • Manage dashboards as code (if Metabase supports it)

8.1 Performance Optimization​

  • Enable query caching in Metabase:

    • Configure query result caching (Settings → Admin → Caching)
    • Set cache TTL based on data freshness requirements
    • Monitor cache hit rates
  • Set up result caching for frequently accessed dashboards:

    • Enable dashboard caching for popular dashboards
    • Configure cache invalidation rules
  • Monitor and adjust Cloud Run resources (CPU/memory):

    • Review Cloud Run metrics weekly
    • Adjust resources based on actual usage patterns
    • Consider scaling up for peak usage times
  • Optimize SQL queries for better performance:

    • Add database indexes on frequently queried columns
    • Review slow query logs
    • Optimize dashboard queries with proper aggregations

8.2 Row-Level Security (RLS)​

  • Evaluate need for PostgreSQL RLS
  • Create RLS policies for test tables
  • Gradually enable RLS on non-critical tables
  • Enable RLS on critical tables (sales, inventory, etc.)

8.3 Additional Features​

  • Create more dashboards:

    • Inventory dashboard
    • Customer analytics dashboard
    • Product performance dashboard
    • Financial reports dashboard
  • Set up automated reports:

    • Scheduled email reports
    • Weekly/monthly summaries

Testing Checklist​

Staging Environment​

  • Metabase UI is accessible ✅
  • Metabase connects to metadata database ✅
  • Metabase connects to app database (flowpos-db) (Phase 4.2)
  • Can create SQL questions (Phase 5.1)
  • Can create dashboards (Phase 5.1)
  • Backend endpoint returns valid embed URLs ✅
  • Frontend component renders dashboards ✅
  • Frontend component automatically gets businessId from context ✅
  • Test component available at /reports/TestDashboard ✅
  • business_id parameter is locked (ready to test once dashboards created)
  • Data isolation works (different businesses see different data) (ready to test)
  • Date filters work correctly (ready to test)

Production Environment​

  • Metabase UI is accessible ✅
  • Metabase connects to metadata database ✅
  • Metabase connects to app database (flowpos-db-production) (Phase 4.4)
  • Can create SQL questions (Phase 5.3)
  • Can create dashboards (Phase 5.3)
  • Backend endpoint returns valid embed URLs ✅
  • Frontend component renders dashboards ✅
  • Frontend component automatically gets businessId from context ✅
  • business_id parameter is locked (ready to test once dashboards created)
  • Data isolation works (different businesses see different data) (ready to test)
  • Date filters work correctly (ready to test)
  • Security restrictions are in place (Phase 6.1)
  • Monitoring is configured (Phase 6.3)

Rollback Plan​

If issues occur during deployment:

  1. Metabase deployment fails:

    • Check Cloud Run logs
    • Verify Cloud SQL connections
    • Verify environment variables
    • Rollback to previous Cloud Run revision if needed
  2. Embedding doesn't work:

    • Verify JWT secret matches in both services
    • Check backend logs for errors
    • Verify dashboard ID is correct
    • Test embed URL generation manually
  3. Database connection issues:

    • Verify Cloud SQL instance is running (state should be RUNNABLE)
    • Check IAM permissions (service account needs roles/cloudsql.client)
    • Verify Cloud SQL instances are configured in Cloud Run annotations
    • Check if socat started successfully (look for "socat is running" in logs)
    • Verify Unix sockets are available at /cloudsql/INSTANCE/.s.PGSQL.5432
    • Check environment variables (CLOUD_SQL_INSTANCE_METADATA, CLOUD_SQL_INSTANCE_APP)
    • Review socat logs: /tmp/socat-metadata.log and /tmp/socat-app.log

Notes & Decisions​

Key Decisions​

  • Multi-tenant strategy: Using locked business_id parameters (Option 1) initially
  • Database separation: Separate Cloud SQL instance for Metabase metadata
  • Deployment: Single Metabase instance per environment (not per tenant)
  • Security: Embedded dashboards only (no direct Metabase UI access for customers)
  • Cloud SQL Connection Method:
    • Uses Cloud Run's built-in Cloud SQL Proxy (via --add-cloudsql-instances)
    • socat approach: TCP forwarding to Unix sockets (see Architecture section)
    • No VPC connector required (Cloud Run handles Cloud SQL Proxy internally)
  • Resource Allocation:
    • Memory: 2Gi (to handle complex queries)
    • CPU: 2 (for better query performance)
    • Timeout: 600s (for long-running queries and Metabase initialization)
    • Min instances: 1 (to avoid cold starts)
