FAQPage Schema

How do I add a required field to a Convex database without causing downtime?▼

To add a required field safely, first introduce it as optional, backfill existing records with valid data, and then enforce the required constraint. This zero-downtime migration approach ensures continuous application availability.

What is the best way to restructure tables and change field types in a Convex schema migration?▼

The best way to handle table restructuring and type modifications is through structured schema migrations using batch processing and scheduled execution. This safely manages breaking changes while preserving overall data integrity.

How does a dual-write pattern work for zero-downtime schema migrations?▼

A dual-write pattern works for zero-downtime migrations by simultaneously writing data to both the old and new schema structures. This enables gradual backfilling and verification before fully deprecating the old structure.

Can I use batch processing to backfill existing data during a Convex migration?▼

Yes, you can use batch processing to backfill existing data during a Convex migration. This technique processes records in chunks, preventing system overload and maintaining application performance during large data updates.

When do I need to use a structured schema migration instead of direct database updates?▼

You need a structured schema migration for complex additive and breaking changes like field additions, type modifications, and table restructuring. It enforces migration principles to guarantee data integrity that direct updates lack.
