Why teams connect AWS Aurora MySQL and TiDB

Keep AWS Aurora 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 AWS Aurora 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

  • 01 Stream row changes from Aurora into SaaS tools via binlog CDC instead of scheduled batch exports.
  • 02 Sync a production Aurora cluster with an analytics database while filtering out sensitive columns.
  • 03 Serve mixed transactional and analytical workloads on synced data using TiFlash columnar replicas
  • 04 Two-way sync between TiDB tables and SaaS tools so operational edits made in either system converge

Common sync patterns

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 AWS Aurora 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.

What you can sync between AWS Aurora 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.

AWS Aurora MySQL objects TiDB objects How this pairing syncs
Tables The primary sync unit; each table maps one-to-one to a table or object in the paired system. Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Columns MySQL data types are mapped to the paired system's field types during schema setup. Columns MySQL-compatible types mapped to fields in the paired system. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Can serve as read-only sync sources for derived or filtered datasets. Views Logical views for shaping reads before syncing outward. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Foreign keys Express relationships that syncs preserve when mapping to related objects elsewhere. Databases MySQL-style schemas addressed by any MySQL-compatible client. Foreign keys is specific to AWS Aurora MySQL and Databases to TiDB — each maps to any object or custom field on the other side.
Stored procedures and triggers Existing database logic keeps firing on rows written by a sync. Indexes Secondary indexes that keep incremental sync queries efficient. Stored procedures and triggers is specific to AWS Aurora MySQL and Indexes to TiDB — each maps to any object or custom field on the other side.
Databases (schemas) Logical namespaces that scope which tables a sync connection can see. Sequences Server-side ID generation relevant when external systems write rows. Databases (schemas) is specific to AWS Aurora MySQL and Sequences to TiDB — each maps to any object or custom field on the other side.

How changes propagate between AWS Aurora MySQL and TiDB

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

AWS Aurora MySQL TiDB Sub-second propagation

DetectionChanges in AWS Aurora MySQL are captured at the source via change data capture — no polling loop against its API. Log-based CDC via the MySQL binary log (binlog), with polling on timestamp columns as a fallback.

DeliveryEach detected change is applied to TiDB as a row-level write, with types converted between the two schemas.

TiDB AWS Aurora MySQL Sub-second propagation

DetectionChanges in TiDB are captured at the source via change data capture — no polling loop against its API. Log-based CDC via TiCDC, which captures row changes from TiKV and streams them to downstream sinks.

DeliveryEach detected change is applied to AWS Aurora MySQL as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • TiDB: Throughput scales with cluster size rather than fixed API quotas.
