PostgreSQL Generated Columns and Expression Indexes for Multi-Tenant SaaS
📰 Dev.to · SoftwareDevs mvpfactory.io
Optimize PostgreSQL queries for multi-tenant SaaS using generated columns and expression indexes, reducing computation time and improving performance
Action Steps
- Create a STORED generated column in PostgreSQL to store computed values
- Use GIN expression indexes on JSONB tenant configuration data to speed up queries
- Configure partial indexes scoped per tenant to reduce index size and improve query performance
- Utilize the pg_stat_user_indexes visibility trick to detect dead indexes and optimize index maintenance
- Apply a migration strategy to add generated columns without rewriting tables, compatible with PG 16+
