Why teams connect Amazon Aurora and CockroachDB

Keep Amazon Aurora and CockroachDB 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 Amazon Aurora and CockroachDB 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 Two-way sync between Aurora application tables and a CRM so product data and account data stay consistent.
  • 02 Stream row-level changes from Aurora into a warehouse for near-real-time analytics without batch exports.
  • 03 Write application events from CockroachDB back to CRM fields to give go-to-market teams product context.
  • 04 Use changefeeds to propagate row changes from a multi-region cluster into a warehouse or search index.

Common sync patterns

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 Amazon Aurora and CockroachDB, so each workload runs on the engine that suits it.

What you can sync between Amazon Aurora and CockroachDB

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.

Amazon Aurora objects CockroachDB objects How this pairing syncs
Databases Logical databases within a cluster that scope a sync connection. Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Schemas Namespaces (PostgreSQL) or database-level grouping (MySQL) used in table selection. Schemas Namespaces within a database used to isolate synced tables from application tables. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables Relational tables synced bi-directionally at row level. Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Read-only query-backed sources for downstream syncs. Views Read-only projections used as curated sync sources. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Columns and Data Types Standard MySQL or PostgreSQL types mapped during field mapping. Sequences ID generators that matter when writes originate from an external system. Columns and Data Types is specific to Amazon Aurora and Sequences to CockroachDB — each maps to any object or custom field on the other side.
Primary and Foreign Keys Constraints used to identify records and preserve relational integrity in syncs. Changefeeds Built-in CDC streams that emit row-level changes to external sinks. Primary and Foreign Keys is specific to Amazon Aurora and Changefeeds to CockroachDB — each maps to any object or custom field on the other side.

How changes propagate between Amazon Aurora and CockroachDB

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.

Amazon Aurora CockroachDB Sub-second propagation

DetectionChanges in Amazon Aurora are captured at the source via change data capture — no polling loop against its API. Log-based CDC: binlog on MySQL-compatible clusters, logical replication/decoding on PostgreSQL-compatible clusters.

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

CockroachDB Amazon Aurora Sub-second propagation

DetectionChanges in CockroachDB are captured at the source via change data capture — no polling loop against its API. CDC via changefeeds, which stream row-level changes.

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

Rate-limit considerations

  • Amazon Aurora: No API rate limits for wire-protocol access; throughput is bounded by instance class and connection limits.
  • CockroachDB: No API rate limits in the SaaS sense; throughput is bounded by cluster capacity.
