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

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

Common sync patterns

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 How this pairing syncs
Indexes The core container; synced records land in indexes with defined mappings Indexes Static and auto indexes used to query documents for filtered reads Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Documents JSON records written via the index and bulk APIs and read via search queries Documents JSON records, the primary unit read and written during sync Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Ingest pipelines Server-side processors that transform documents as they are written Counters Numeric values attached to documents that change independently of the document body Ingest pipelines is specific to OpenSearch and Counters to RavenDB — each maps to any object or custom field on the other side.
Data streams Append-oriented time-series storage for logs and events pushed from source systems Time series Timestamped measurements stored per document, synced for metrics analysis Data streams is specific to OpenSearch and Time series to RavenDB — each maps to any object or custom field on the other side.
Snapshots Backup artifacts, relevant when reseeding an index from a repository Data subscriptions Server-side change feeds that push matching documents to consumers Snapshots is specific to OpenSearch and Data subscriptions to RavenDB — each maps to any object or custom field on the other side.
Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills Collections Groupings of documents by type, mapped to tables in relational targets Index aliases is specific to OpenSearch and Collections to RavenDB — each maps to any object or custom field on the other side.

How changes propagate between OpenSearch 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.

OpenSearch RavenDB Interval-based propagation

DetectionStacksync polls OpenSearch for changes on an incremental schedule, reading only records changed since the previous pass. No native change feed.

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

RavenDB OpenSearch 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 written to OpenSearch through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • OpenSearch: Throughput bounded by cluster sizing rather than fixed API quotas.
  • RavenDB: Throughput bounded by cluster resources rather than API quotas.
