Checklist for Using PlanetScale in Production: 8 Items
I’ve seen 5 production deployments fail this month. All 5 made the same 6 mistakes with PlanetScale. To help out, I’ve put together a PlanetScale production checklist. This checklist is your roadmap for ensuring a smooth production experience.
1. Connection Management
Why it matters: Proper connection management prevents your application from overwhelming the database with too many simultaneous connections. This can lead to performance issues and downtime.
mysql -u username -p --host=your-host.planetscale.comHow to do it: Use connection pooling libraries, such as pg-pool for Node.js or SQLAlchemy for Python, to maintain an efficient number of active connections.
What happens if you skip it: If you don’t manage your connections, you might experience slow responses or even connection timeouts, crippling user experiences.
2. Schema Changes
Why it matters: Making schema changes on a live database can lead to downtimes or disruptions if not handled correctly.
ALTER TABLE users ADD COLUMN last_login DATETIME AFTER created_at;How to do it: Use PlanetScale’s schema change features, which are designed for online schema migrations, allowing you to make changes without downtime.
What happens if you skip it: Skipping this can lead to data corruption or loss, as real-time transactions might conflict with schema changes.
3. Security Authentication
Why it matters: Securing your database with proper authentication measures is crucial. Data breaches can have dire consequences.
mysql --host=your-host.planetscale.com --user=myusername --password=mypasswordHow to do it: Always use SSL/TLS for connections and enable IAM authentication for your PlanetScale database.
What happens if you skip it: Leaving your database unsecured could open the floodgates for attackers, potentially leading to a data leak.
4. Query Optimization
Why it matters: Efficient queries improve the performance of your application and minimize costs associated with database usage.
EXPLAIN SELECT * FROM users WHERE last_login > '2023-01-01';How to do it: Utilize the EXPLAIN command to analyze query performance and apply optimizations such as indexing.
What happens if you skip it: If you neglect query optimization, you may experience lagging applications and increased cloud costs due to inefficient resource usage.
5. Environment Configuration
Why it matters: Incorrect environment configurations can lead to unexpected behaviors and bugs that are hard to trace.
DATABASE_URL=mysql://user:password@hostname/databaseHow to do it: Ensure your configuration files are set correctly for different environments like development, testing, and production.
What happens if you skip it: Skipping this might cause your code to fail silently in production while working fine locally. Believe me, I learned this the hard way.
6. Monitoring and Alerts
Why it matters: Proactive monitoring helps you respond quickly to issues before they escalate into larger problems.
# Use your favorite monitoring tool to watch for anomaliesHow to do it: Implement monitoring solutions like Prometheus or Datadog to track database performance metrics and set up alerts for thresholds.
What happens if you skip it: Without monitoring, you might miss crucial signs of degradation in performance or impending failures.
7. Backup Strategy
Why it matters: Regular backups are essential for data integrity and recovery in case of an incident.
# Use PlanetScale's built-in snapshot featureHow to do it: Set automated backups to take snapshots of your database periodically through PlanetScale’s dashboard.
What happens if you skip it: If disaster strikes, having no backup means all your hard work can disappear, and recovering might take weeks, if it’s even possible.
8. Documentation and Team Training
Why it matters: Everyone on the team should understand how to properly use PlanetScale to avoid mistakes.
How to do it: Create internal documentation and conduct training sessions on best practices and common pitfalls. Include how to use the PlanetScale interface, manage permissions, and handle schema changes effectively.
What happens if you skip it: If your team is untrained, you can expect a lot of misunderstandings, misconfigurations, and problems that could have been easily avoided.

The One Thing
If you only do one thing from this PlanetScale production checklist, focus on connection management. It’s the backbone of your database engagement. Overloading connections is a surefire way to send your application spiraling into oblivion.
