Why teams connect AWS Aurora PostgreSQL and TiDB

Keep AWS Aurora PostgreSQL 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 PostgreSQL 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

  • Feed operational dashboards from a read replica while the writer handles sync traffic.
  • Expose ERP records such as customers, orders, and invoices as Postgres tables the engineering team can query and update with plain SQL.
  • Serve mixed transactional and analytical workloads on synced data using TiFlash columnar replicas
  • Two-way sync between TiDB tables and SaaS tools so operational edits made in either system converge

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.

Regional or environment copies

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

What you can sync between AWS Aurora PostgreSQL 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 PostgreSQL objects TiDB objects
Primary keys and constraints Identify rows for upserts and enforce integrity on sync writes. Views Logical views for shaping reads before syncing outward.
Views and materialized views Usable as read-only sources for filtered or precomputed sync datasets. Columns MySQL-compatible types mapped to fields in the paired system.
Foreign keys Relationship metadata that syncs can translate into object references elsewhere. Indexes Secondary indexes that keep incremental sync queries efficient.
Replication slots and publications The logical replication objects that power log-based CDC. Sequences Server-side ID generation relevant when external systems write rows.
Databases and schemas PostgreSQL's two-level namespace scopes which tables a sync connection targets. Databases MySQL-style schemas addressed by any MySQL-compatible client.
Tables The core sync unit; rows are matched across systems by primary key. Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC.

How the AWS Aurora PostgreSQL and TiDB connectors work

AWS Aurora PostgreSQL

Integration surface
SQL wire protocol (PostgreSQL-compatible), standard Postgres drivers and JDBC
Authentication
Database credentials, optionally AWS IAM database authentication, over TLS
Change detection
Log-based CDC via PostgreSQL logical replication (WAL decoding through replication slots), with timestamp polling as a fallback
Capabilities
read · write · CDC

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
