Two-way sync
Changes in Google AlloyDB or OpenSearch instantly reflect in both systems. No stale data, no manual imports.
Keep Google AlloyDB and OpenSearch 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 Google AlloyDB and OpenSearch 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.
Keep the same dataset live in both Google AlloyDB and OpenSearch, so each workload runs on the engine that suits it.
When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.
Services that own separate databases stay consistent on the records they share, without a custom replication layer.
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.
| Google AlloyDB objects | OpenSearch objects | |
|---|---|---|
| Materialized Views Precomputed aggregates refreshed and synced outward on a schedule. | Snapshots Backup artifacts, relevant when reseeding an index from a repository | |
| Indexes Keep sync key lookups fast on high-volume tables. | Indexes The core container; synced records land in indexes with defined mappings | |
| Sequences ID generation relevant when external systems insert rows. | Documents JSON records written via the index and bulk APIs and read via search queries | |
| Replication Slots Logical replication artifacts that back log-based change capture. | Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills | |
| Databases Standard PostgreSQL databases within an AlloyDB cluster that syncs connect to. | Index templates Mapping and settings presets applied to new indexes a sync creates | |
| Schemas Namespaces used to separate synced SaaS data from application tables. | Ingest pipelines Server-side processors that transform documents as they are written |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Google AlloyDB–OpenSearch connection.
Changes in Google AlloyDB or OpenSearch instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Google AlloyDB or OpenSearch data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Google AlloyDB or OpenSearch record.
Track your Google AlloyDB ⇄ OpenSearch sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Google AlloyDB and OpenSearch.
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 Google AlloyDB and OpenSearch 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 Google AlloyDB and OpenSearch 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 Google AlloyDB and OpenSearch: authenticate both systems, choose the objects to sync (such as Google AlloyDB's Materialized Views and Indexes), map fields visually, and changes propagate both ways in milliseconds — no code required.
Common patterns for Google AlloyDB and OpenSearch: Cross-engine sync; Migration with zero-downtime cutover; Shared reference data between services. Keep the same dataset live in both Google AlloyDB and OpenSearch, so each workload runs on the engine that suits it.
Google AlloyDB: SQL wire protocol (PostgreSQL-compatible), with connectivity through the AlloyDB Auth Proxy or private IP. Authentication: Database credentials or IAM database authentication. OpenSearch: REST API over HTTP(S) with JSON payloads. Authentication: Basic authentication with the security plugin, or AWS IAM request signing on Amazon OpenSearch Service. Stacksync manages authentication, retries, and rate limits on both sides.
Google AlloyDB: It supports PostgreSQL logical replication, enabling log-based change capture from the write-ahead log. OpenSearch: OpenSearch exposes no built-in change feed, so it usually serves as a sync destination with sources pushing documents in through the bulk API. Stacksync's field mapping accounts for these differences between Google AlloyDB and OpenSearch 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 Google AlloyDB and OpenSearch records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Google AlloyDB and OpenSearch connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Google AlloyDB–OpenSearch 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.
