Why teams connect MySQL and TiDB

Keep MySQL 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 MySQL 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

  • Two-way sync between a MySQL application database and a CRM so operational records and sales records stay identical
  • Expose SaaS objects as MySQL tables so legacy internal tools built on MySQL can read live business data
  • Consolidate formerly sharded MySQL workloads into TiDB and sync the unified data outward to business systems
  • Serve mixed transactional and analytical workloads on synced data using TiFlash columnar replicas

Cross-engine sync

Keep the same dataset live in both MySQL 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.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

What you can sync between MySQL 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.

MySQL objects TiDB objects
Views Read-side projections used as outbound sync sources. Columns MySQL-compatible types mapped to fields in the paired system.
Columns Field-level mapping targets with engine-typed values. Indexes Secondary indexes that keep incremental sync queries efficient.
Primary and Unique Keys Match keys for idempotent upserts and conflict handling. Sequences Server-side ID generation relevant when external systems write rows.
JSON Columns Validated semi-structured payloads for nested SaaS data. Databases MySQL-style schemas addressed by any MySQL-compatible client.
Stored Procedures Server-side logic that can post-process synced rows. Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC.
Triggers An alternative change-capture mechanism when binlog access is unavailable. Views Logical views for shaping reads before syncing outward.
What ships with MySQL ⇄ TiDB

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

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

Real-time

Two-way sync

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

No-code + pro-code

Workflow automation

Trigger automated workflows whenever MySQL 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 MySQL or TiDB record.

Observability

Monitoring

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

Trading partners

EDI

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

How the MySQL and TiDB connectors work

MySQL

Integration surface
SQL wire protocol (MySQL client/server protocol)
Authentication
Database credentials entered as a connection string or parameters, with optional SSL root certificate upload and optional SSH tunnel (SSH user + SSH host)
Change detection
Database triggers — Stacksync creates deterministic triggers for internal logging and syncing (requires log_bin_trust_function_creators=ON when binary logging is enabled)
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by connection limits and server resources
MySQL 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 MySQL 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 MySQL 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 MySQL 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.
