Why teams connect MongoDB and TiDB

Keep MongoDB and TiDB synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between MongoDB and TiDB continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • Capture change stream events and propagate them to SaaS tools in near real time instead of running batch exports.
  • Keep a MongoDB-backed product catalog aligned with an ERP's item master in both directions.
  • Stream row-level changes to a warehouse or Kafka via CDC for near-real-time analytics
  • Serve mixed transactional and analytical workloads on synced data using TiFlash columnar replicas

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

Cross-engine sync

Keep the same dataset live in both MongoDB and TiDB, so each workload runs on the engine that suits it.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

What you can sync between MongoDB and TiDB

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

MongoDB objects TiDB objects
Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. Sequences Server-side ID generation relevant when external systems write rows.
Indexes Keep lookups by sync key fast on large collections. Databases MySQL-style schemas addressed by any MySQL-compatible client.
Views Read-only aggregation-defined sources for filtered sync datasets. Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC.
Change streams The oplog-backed event feed that powers real-time change capture. Views Logical views for shaping reads before syncing outward.
GridFS files Chunked file storage whose metadata can be referenced by synced documents. Columns MySQL-compatible types mapped to fields in the paired system.
Databases Logical groupings of collections that scope a sync connection. Indexes Secondary indexes that keep incremental sync queries efficient.
What ships with MongoDB ⇄ TiDB

Connect MongoDB and TiDB for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every MongoDB–TiDB connection.

Real-time

Two-way sync

Changes in MongoDB or TiDB instantly reflect in both systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever MongoDB or TiDB data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single MongoDB or TiDB record.

Observability

Monitoring

Track your MongoDB ⇄ TiDB sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between MongoDB and TiDB.

How the MongoDB and TiDB connectors work

MongoDB

Integration surface
MongoDB wire protocol via official drivers; Atlas additionally offers an administration REST API for cluster management
Authentication
Database credentials (username/password) or TLS/SSL X.509 certificate (.pem upload), entered individually or via a MongoDB connection string (SRV or standard); Stacksync IP allowlisting required
Change detection
MongoDB oplog and change streams (requires the database to run as a replica set — even single-node); Stacksync leverages these built-in tools to track changes in real time
Capabilities
read · write · CDC
MongoDB setup guide

TiDB

Integration surface
MySQL wire protocol (SQL)
Authentication
Database credentials (MySQL-compatible username/password)
Change detection
Log-based CDC via TiCDC, which captures row changes from TiKV and streams them to downstream sinks; polling also works
Capabilities
read · write · CDC
Rate limits
Throughput scales with cluster size rather than fixed API quotas
How it works

How to connect MongoDB to TiDB — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate MongoDB and TiDB with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

    Choose tables

    Pick the MongoDB and TiDB objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
