Why teams migrate from DynamoDB to Firestore
Good fit when
- +Teams migrating NoSQL workloads to GCP alongside other service migrations.
- +Applications with document-oriented access patterns that map well to Firestore collections.
- +Teams wanting real-time listeners and offline sync capabilities that Firestore provides natively.
Strengths
- Firestore's real-time listeners and offline sync are built-in.
- Document/collection model is intuitive for hierarchical data.
- Native integration with Firebase ecosystem and GCP services.
Tradeoffs
- DynamoDB's partition/sort key model must be redesigned for Firestore's document/collection hierarchy.
- DynamoDB Streams have no direct Firestore equivalent; use Firestore triggers with Cloud Functions instead.
- Throughput pricing model differs significantly from DynamoDB's on-demand/provisioned capacity.
Migration notes
- Redesign table schemas from partition/sort key patterns to Firestore document/collection hierarchy.
- Export DynamoDB data and transform to Firestore document format before import.
- Remap DynamoDB Streams consumers to Firestore-triggered Cloud Functions.
- Rewrite query patterns from DynamoDB Query/Scan to Firestore collection queries.
