Why teams connect OpenSearch and RavenDB

Keep OpenSearch 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 OpenSearch 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

  • Sync product catalogs from an ERP or database into the indexes that back storefront search.
  • Keep Postgres as the source of truth while mirroring rows to OpenSearch for full-text and vector queries.
  • Consolidate documents from distributed RavenDB clusters into one reporting store.
  • Keep external search indexes or caches current from RavenDB change feeds without custom pollers.

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

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.

What you can sync between OpenSearch 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.

OpenSearch objects RavenDB objects
Snapshots Backup artifacts, relevant when reseeding an index from a repository Data subscriptions Server-side change feeds that push matching documents to consumers
Indexes The core container; synced records land in indexes with defined mappings Documents JSON records, the primary unit read and written during sync
Documents JSON records written via the index and bulk APIs and read via search queries Collections Groupings of documents by type, mapped to tables in relational targets
Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills Indexes Static and auto indexes used to query documents for filtered reads
Index templates Mapping and settings presets applied to new indexes a sync creates Attachments Binary payloads stored with documents, handled separately from the JSON body
Ingest pipelines Server-side processors that transform documents as they are written Revisions Historical versions of documents, useful for audit-oriented replication

How the OpenSearch and RavenDB connectors work

OpenSearch

Integration surface
REST API over HTTP(S) with JSON payloads
Authentication
basic authentication with the security plugin, or AWS IAM request signing on Amazon OpenSearch Service
Change detection
no native change feed; reads rely on queries with scroll or point-in-time polling
Capabilities
read · write
Rate limits
throughput bounded by cluster sizing rather than fixed API quotas

RavenDB

Integration surface
HTTP REST API with official clients (.NET, Java, Node.js, Python, and others)
Authentication
X.509 client certificates on secured servers, instead of username and password
Change detection
data subscriptions and the Changes API provide server-pushed change feeds
Capabilities
