Why teams connect CockroachDB and VoltDB

Keep CockroachDB and VoltDB 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 CockroachDB and VoltDB 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

  • Write application events from CockroachDB back to CRM fields to give go-to-market teams product context.
  • Use changefeeds to propagate row changes from a multi-region cluster into a warehouse or search index.
  • Sync customer or account reference data from a CRM into VoltDB replicated tables for in-transaction lookups such as fraud or policy checks.
  • Stream committed VoltDB results out through export targets into a warehouse for historical analysis.

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 CockroachDB and VoltDB

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.

CockroachDB objects VoltDB objects
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Stored Procedures Precompiled transactional units that serve as the primary write interface.
Schemas Namespaces within a database used to isolate synced tables from application tables. Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources.
Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. Streams Insert-only constructs that feed the export subsystem with committed rows.
Views Read-only projections used as curated sync sources. Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks.
Indexes Secondary indexes that keep sync lookup queries fast on key columns. Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target.
Sequences ID generators that matter when writes originate from an external system. Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data.
