Why teams connect Postgres Heroku and TiDB

Keep Postgres Heroku 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 Postgres Heroku 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

  • Reflect billing and subscription records into the app database so product logic reads local rows
  • Expose CRM objects as Postgres tables the Heroku application can query and join directly
  • 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

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.

Cross-engine sync

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

What you can sync between Postgres Heroku 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.

Postgres Heroku objects TiDB objects
Schemas Namespaces that scope which tables a sync reads and writes. Sequences Server-side ID generation relevant when external systems write rows.
Primary and Unique Keys Match keys for idempotent upserts from connected systems. Databases MySQL-style schemas addressed by any MySQL-compatible client.
JSONB Columns Semi-structured payloads for nested SaaS objects and metadata. Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC.
Sequences Generate surrogate keys for rows created by inbound syncs. Views Logical views for shaping reads before syncing outward.
Follower Databases Heroku-managed read replicas usable as low-impact sync sources. Columns MySQL-compatible types mapped to fields in the paired system.
Tables Standard Postgres tables; the primary two-way sync target for app data. Indexes Secondary indexes that keep incremental sync queries efficient.

EDI

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

How the Postgres Heroku and TiDB connectors work

Postgres Heroku

Integration surface
SQL wire protocol (standard PostgreSQL)
Authentication
Database credentials from the Heroku DATABASE_URL config var; SSL required
Change detection
Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings
Capabilities
read · write
Rate limits
No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan

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
