Two-way sync
Changes in OpenSearch or TiDB instantly reflect in both systems. No stale data, no manual imports.
Keep OpenSearch and TiDB 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 OpenSearch and TiDB 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.
Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.
Keep the same dataset live in both OpenSearch and TiDB, 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.
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 | TiDB objects | |
|---|---|---|
| Documents JSON records written via the index and bulk APIs and read via search queries | Databases MySQL-style schemas addressed by any MySQL-compatible client. | |
| Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills | Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC. | |
| Index templates Mapping and settings presets applied to new indexes a sync creates | Views Logical views for shaping reads before syncing outward. | |
| Ingest pipelines Server-side processors that transform documents as they are written | Columns MySQL-compatible types mapped to fields in the paired system. | |
| Data streams Append-oriented time-series storage for logs and events pushed from source systems | Indexes Secondary indexes that keep incremental sync queries efficient. | |
| Snapshots Backup artifacts, relevant when reseeding an index from a repository | Sequences Server-side ID generation relevant when external systems write rows. |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every OpenSearch–TiDB connection.
Changes in OpenSearch or TiDB instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever OpenSearch or TiDB data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single OpenSearch or TiDB record.
Track your OpenSearch ⇄ TiDB sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between OpenSearch and TiDB.
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 OpenSearch and TiDB 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 OpenSearch and TiDB 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 OpenSearch and TiDB: authenticate both systems, choose the objects to sync (such as OpenSearch's Documents and Index aliases), map fields visually, and changes propagate both ways in milliseconds — no code required.
On the OpenSearch side: Data streams, Snapshots, Indexes, Documents, plus custom fields where OpenSearch exposes them. On the TiDB side: Tables, Views, Columns, Indexes. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for OpenSearch and TiDB: Regional or environment copies; Cross-engine sync; Migration with zero-downtime cutover. Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.
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. TiDB: MySQL wire protocol (SQL). Authentication: Database credentials (MySQL-compatible username/password). Stacksync manages authentication, retries, and rate limits on both sides.
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. TiDB: TiDB is MySQL-protocol compatible, so existing MySQL drivers, ORMs, and tools connect without modification. Stacksync's field mapping accounts for these differences between OpenSearch and TiDB without custom code.
