Why teams connect Couchbase and RavenDB

Keep Couchbase and RavenDB 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 Couchbase and RavenDB 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 Consolidate documents from multiple Couchbase clusters into a single analytical store.
  • 02 Write cleaned or enriched records from operational databases back into Couchbase collections that applications read.
  • 03 Keep external search indexes or caches current from RavenDB change feeds without custom pollers.
  • 04 Stream RavenDB document changes into Postgres or a warehouse via data subscriptions for SQL analytics.

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 Couchbase and RavenDB, so each workload runs on the engine that suits it.

What you can sync between Couchbase and RavenDB

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 RavenDB objects How this pairing syncs
Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. Collections Groupings of documents by type, mapped to tables in relational targets Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. Counters Numeric values attached to documents that change independently of the document body Global Secondary Indexes is specific to Couchbase and Counters to RavenDB — each maps to any object or custom field on the other side.
XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. Time series Timestamped measurements stored per document, synced for metrics analysis XDCR replications is specific to Couchbase and Time series to RavenDB — each maps to any object or custom field on the other side.
Full-text search indexes Search indexes over documents, relevant when syncing searchable content. Data subscriptions Server-side change feeds that push matching documents to consumers Full-text search indexes is specific to Couchbase and Data subscriptions to RavenDB — each maps to any object or custom field on the other side.
Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. Documents JSON records, the primary unit read and written during sync Buckets is specific to Couchbase and Documents to RavenDB — each maps to any object or custom field on the other side.
Scopes Namespaces inside a bucket used to group collections, similar to schemas. Indexes Static and auto indexes used to query documents for filtered reads Scopes is specific to Couchbase and Indexes to RavenDB — each maps to any object or custom field on the other side.

How changes propagate between Couchbase and RavenDB

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.

Couchbase RavenDB Sub-second propagation

DetectionChanges in Couchbase are captured at the source via change data capture — no polling loop against its API. Database Change Protocol (DCP) streams document mutations.

DeliveryEach detected change is written to RavenDB through its API, with automatic retries and rate-limit backoff.

RavenDB Couchbase Sub-second propagation

DetectionChanges in RavenDB are captured at the source via change data capture — no polling loop against its API. Data subscriptions and the Changes API provide server-pushed change feeds.

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

Rate-limit considerations

  • Couchbase: Throughput is bounded by cluster sizing rather than API rate limits.
  • RavenDB: Throughput bounded by cluster resources rather than API quotas.
