Database Migrations
License Heartbeats Table Migration
Overview
The create_license_heartbeats_table.sql migration creates a partitioned table for storing real-time license validation data. This table is essential for the Live Dashboard & Analytics functionality.
Features
- Monthly partitioning for efficient data management
- Automatic creation of current and next month partitions
- Optimized indexes for performance
- Foreign key relationship with licenses table
Running the Migration
Option 1: Using the Python Script
cd /path/to/v2_adminpanel
python apply_license_heartbeats_migration.py
Option 2: Manual SQL Execution
psql -h postgres -U postgres -d v2_adminpanel -f migrations/create_license_heartbeats_table.sql
Option 3: Docker Exec
docker exec -it v2_adminpanel_postgres psql -U postgres -d v2_adminpanel -f /migrations/create_license_heartbeats_table.sql
Verification
After running the migration, verify the table was created:
-- Check if table exists
SELECT EXISTS (
SELECT 1
FROM information_schema.tables
WHERE table_name = 'license_heartbeats'
);
-- List all partitions
SELECT tablename
FROM pg_tables
WHERE tablename LIKE 'license_heartbeats_%'
ORDER BY tablename;
Partition Management
The system automatically creates partitions as needed. To manually create future partitions:
from utils.partition_helper import create_future_partitions
import psycopg2
conn = psycopg2.connect(...)
create_future_partitions(conn, 'license_heartbeats', months_ahead=6)
Data Retention
Consider implementing a data retention policy to remove old partitions:
-- Drop partitions older than 3 months
DROP TABLE IF EXISTS license_heartbeats_2025_03;
Troubleshooting
-
Table already exists: The migration is idempotent and will skip creation if the table exists.
-
Permission denied: Ensure the database user has CREATE privileges.
-
Foreign key violation: The licenses table must exist before running this migration.
