MongoDB → PostgreSQL
AI-first ETL from MongoDB into PostgreSQL. Governed entities, incremental sync, typed landing tables.
How Datrise loads MongoDB into PostgreSQL
Datrise syncs MongoDB's collections, documents, change streams, and schema snapshots into PostgreSQL as a typed table per source entity. Flexible or custom fields land in jsonb columns, and timestamps such as created, updated, and status changes are typed as timestamptz.
Sync is incremental: Datrise uses a watermark on each entity's updated-at, applied with INSERT … ON CONFLICT DO UPDATE, so re-runs update only what changed. Optional declarative range partitioning by load date for high-volume tables. PostgreSQL folds unquoted identifiers to lowercase, so Datrise normalizes mixed-case source fields to snake_case.
Ideal for operational analytics and application backends that need fresh, queryable copies of your data.
Endpoints
MongoDB: Document database often used as an operational source for analytics.
PostgreSQL: Open-source relational database with strong SQL and extensions.
How MongoDB entities map to PostgreSQL
| MongoDB entity | PostgreSQL object | Notes |
|---|---|---|
| collections | mongodb_collections | id PK · custom fields → jsonb columns |
| documents | mongodb_documents | id PK · linked to mongodb_collections |
| change streams | mongodb_change_streams | timestamptz events |
| schema snapshots | mongodb_schema_snapshots | id PK · linked to mongodb_collections |
FAQ
How does Datrise handle MongoDB's custom fields in PostgreSQL?
Flexible values are stored as jsonb columns, so new fields don't require a migration; strongly-typed fields — dates, numbers, and references — are promoted to native PostgreSQL types.
How does the MongoDB to PostgreSQL sync stay up to date?
It runs incrementally — Datrise uses a watermark on each entity's updated-at, applied with INSERT … ON CONFLICT DO UPDATE.
