Two-way sync
Changes in Couchbase or VoltDB instantly reflect in both systems. No stale data, no manual imports.
Keep Couchbase and VoltDB in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Couchbase 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.
Services that own separate databases stay consistent on the records they share, without a custom replication layer.
Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.
Keep the same dataset live in both Couchbase and VoltDB, so each workload runs on the engine that suits it.
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.
| Couchbase objects | VoltDB objects | |
|---|---|---|
| Full-text search indexes Search indexes over documents, relevant when syncing searchable content. | Streams Insert-only constructs that feed the export subsystem with committed rows. | |
| Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. | Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. | |
| Scopes Namespaces inside a bucket used to group collections, similar to schemas. | Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. | |
| Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. | Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. | |
| JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. | Stored Procedures Precompiled transactional units that serve as the primary write interface. | |
| Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. | Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Couchbase–VoltDB connection.
Changes in Couchbase or VoltDB instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Couchbase or VoltDB data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Couchbase or VoltDB record.
Track your Couchbase ⇄ VoltDB sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Couchbase and VoltDB.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Couchbase and VoltDB with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Couchbase and VoltDB objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Couchbase and VoltDB: authenticate both systems, choose the objects to sync (such as Couchbase's Full-text search indexes and Buckets), map fields visually, and changes propagate both ways in milliseconds — no code required.
Common patterns for Couchbase and VoltDB: Shared reference data between services; Regional or environment copies; Cross-engine sync. Services that own separate databases stay consistent on the records they share, without a custom replication layer.
Couchbase: SQL++ (N1QL) query service, key-value SDK APIs, and REST management APIs. Authentication: Database credentials with role-based access control, typically over TLS. VoltDB: SQL over JDBC plus native client libraries and an HTTP/JSON interface. Authentication: Database credentials. Stacksync manages authentication, retries, and rate limits on both sides.
Couchbase: SQL++ (N1QL) provides SQL-style querying over JSON documents, including joins across collections, so extraction can be query-shaped rather than key-by-key. VoltDB: Data is held in memory, with durability provided by command logging and periodic snapshots. Stacksync's field mapping accounts for these differences between Couchbase and VoltDB without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Couchbase and VoltDB records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Couchbase and VoltDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Couchbase–VoltDB integration in-house.
As a data company, we understand the importance of keeping your data secure. Stacksync is built with security best practices to keep your data safe at every layer, and is DPF-certified for US, EU, UK and CH data transfers.
Let your users access Stacksync from your centralized user management systems. Works with Okta, Azure, Google SSO and more.
Immediately get alerted about record syncing issues over email, Slack, PagerDuty and WhatsApp. Resolve issues from a centralized dashboard with retry and revert options.
