How does PlanetScale differ from traditional managed MySQL services?

PlanetScale is built on Vitess (MySQL-compatible horizontal sharding) and introduces a Git-like database branching model for schema changes, enabling non-blocking DDL and zero-downtime deployments. It's particularly popular for SaaS applications with high growth trajectories and teams practicing continuous deployment.

What are the key performance tuning parameters for managed MySQL?

Critical MySQL performance parameters include innodb_buffer_pool_size (ideally 70–80% of available RAM), max_connections, innodb_log_file_size, query_cache_type (disable in MySQL 8+), and slow_query_log. Managed services typically expose these via parameter groups (AWS RDS) or database flags (Google Cloud SQL).

How do enterprises migrate from on-premises MySQL to managed cloud services?

AWS DMS supports MySQL-to-MySQL migrations with minimal downtime using CDC (Change Data Capture). Percona XtraBackup enables physical backup-based migration for large datasets. PlanetScale Import provides a guided migration path from external MySQL. For large databases (>1 TB), parallel dump/restore with mydumper/myloader reduces migration windows significantly.
