Why teams connect Google Cloud Spanner and TiDB

Keep Google Cloud Spanner 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 Google Cloud Spanner 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

  • Run a two-way sync between Spanner and a SaaS tool so edits made by ops teams land back in the application database.
  • Consolidate data from a globally distributed Spanner deployment into regional business systems.
  • Two-way sync between TiDB tables and SaaS tools so operational edits made in either system converge
  • Stream row-level changes to a warehouse or Kafka via CDC for near-real-time analytics

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 Google Cloud Spanner 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 Google Cloud Spanner 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.

Google Cloud Spanner objects TiDB objects
Secondary indexes Used to make incremental read queries efficient on non-key columns. Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC.
Change streams Capture inserts, updates, and deletes for log-style change data capture. Views Logical views for shaping reads before syncing outward.
Views Read-only projections useful for shaping data before it leaves Spanner. Columns MySQL-compatible types mapped to fields in the paired system.
Databases Top-level containers that scope schema and sync configuration. Indexes Secondary indexes that keep incremental sync queries efficient.
Tables Relational tables mapped one-to-one to sync targets. Sequences Server-side ID generation relevant when external systems write rows.
Rows The unit of read and write in each sync cycle, keyed by primary key. Databases MySQL-style schemas addressed by any MySQL-compatible client.

How the Google Cloud Spanner and TiDB connectors work

Google Cloud Spanner

Integration surface
gRPC/REST client API with SQL query surface (GoogleSQL and PostgreSQL-interface dialects)
Authentication
Google Cloud IAM (service accounts)
Change detection
Change streams (log-style CDC), or timestamp-based polling queries
Capabilities
read · write · CDC
Rate limits
Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.

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
