Firebase to Azure Synapse Integration

How Datrise loads Firebase into Azure Synapse

Datrise syncs Firebase's users, collections, documents, auth events, app events, and security rules into Azure Synapse as a typed table per source entity. Flexible or custom fields land in NVARCHAR(MAX) JSON columns, and timestamps such as created, updated, and status changes are typed as datetime2.

Sync is incremental: Datrise uses COPY into staging, then a MERGE on stable id, so re-runs update only what changed. Hash distribution on the join id with date partitioning on facts. Synapse dedicated pools reward good hash-distribution choices, so Datrise distributes on entity ids to avoid data-movement-heavy joins.

Ideal for Azure analytics estates feeding Power BI.

Endpoints

Firebase: App backend with auth, storage, and analytics.

Azure Synapse: Microsoft analytics workspace with SQL pools.

How Firebase entities map to Azure Synapse

Firebase entity	Azure Synapse object	Notes
users	`firebase_users`	id PK · custom fields → NVARCHAR(MAX) JSON columns
collections	`firebase_collections`	id PK · linked to firebase_users
documents	`firebase_documents`	id PK · linked to firebase_users
auth events	`firebase_auth_events`	datetime2 events

FAQ

How does Datrise handle Firebase's custom fields in Azure Synapse?

Flexible values are stored as NVARCHAR(MAX) JSON columns, so new fields don't require a migration; strongly-typed fields — dates, numbers, and references — are promoted to native Azure Synapse types.

How does the Firebase to Azure Synapse sync stay up to date?

It runs incrementally — Datrise uses COPY into staging, then a MERGE on stable id.
