How data syncs from Azure Document DB to in-app SQLite
PowerSync connects to your DocumentDB database with only the limited permissions needed.
PowerSync automatically handles changes in document structure and JSON Schema with no need for client-side migrations.
The PowerSync Service uses DocumentDB change streams to detect insert, update and delete operations on documents.
The PowerSync Service tracks changes to data in the buckets, allowing for efficient delta syncing to clients.
You define Sync Streams which determine which data is synced to which users. Data is grouped and shared efficiently between users to avoid duplication.
Clients authenticate against the PowerSync Service using JWTs.
The client SDK initially downloads all relevant data and then incrementally keeps it updated, in real time.
Writes are immediately applied locally, and queued for upload to your backend API. The PowerSync client SDK automatically handles failures and retries.
On the client, data is persisted to a SQLite database in schemaless format. The application defines a client-side schema which is applied as SQLite views.
Live reactive queries can be used to update the UI when data changes.
PowerSync uses a server-authoritative architecture with a checkpoint system to guarantee consistency.
Your backend accepts uploaded writes and then applies them to your DocumentDB database.
