BSON Schema Detection
Automatically detect field types across all collections — ObjectId, ISODate, NumberInt, nested objects, and arrays — and map them to SQL equivalents.
ObjectId → UUIDMongoDB Oplog CDC
Tail the MongoDB oplog in real time. Every insert, update, and delete flows to the SQL target with sub-second latency. Zero data loss guaranteed.
< 50ms latencyType Coercion Engine
Flexible MongoDB types don't break your schema. ISODate → TIMESTAMPTZ, NumberInt → INTEGER, Double → DOUBLE PRECISION. Custom overrides available.
Auto type mappingZero Downtime Cutover
Dual-write mode keeps MongoDB and the SQL target in sync during migration. Cut over when you're ready — with automatic rollback.
Dual-write modeIncremental Sync
Migrate historical data in bulk, then keep new writes in sync via CDC. No need to pause your application. Works with collections of any size.
Bulk + streamingSchema Validation
Before migrating, validate that every document conforms to the inferred schema. Catch type mismatches early. Drill down to individual offending documents.

Frequently asked questions
Embedded documents become JSONB columns by default, with full PostgreSQL indexing support. You can optionally flatten specific fields into their own columns using the visual schema mapper.
ObjectIds are automatically mapped to UUID in PostgreSQL. All references and foreign key relationships are preserved. Legacy ObjectId strings can be kept in a companion column.
Yes. Choose which MongoDB collections to migrate. Each collection becomes a separate SQL table. Filter documents with queries to migrate only a subset.
A typical 100 GB dataset migrates in under 2 hours with bulk mode. With CDC enabled, ongoing writes sync in real time. Total time depends on data volume and network throughput.
Yes. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). Database credentials use short-lived tokens. Migration workers run in an isolated environment and never store data after the job completes.
Yes. Dual-write mode keeps both databases in sync. If you detect issues after cutover, just reverse to the source in one click. Your original data is never modified.
