Two-way sync
Changes in InterSystems IRIS or TiDB instantly reflect in both systems. No stale data, no manual imports.
Keep InterSystems IRIS 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 InterSystems IRIS 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.
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.
Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.
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.
| InterSystems IRIS objects | TiDB objects | How this pairing syncs | |
|---|---|---|---|
| Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. | Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Views SQL views expose curated slices of data for outbound replication. | Views Logical views for shaping reads before syncing outward. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. | Indexes Secondary indexes that keep incremental sync queries efficient. | Persistent Classes is specific to InterSystems IRIS and Indexes to TiDB — each maps to any object or custom field on the other side. | |
| Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. | Sequences Server-side ID generation relevant when external systems write rows. | Globals is specific to InterSystems IRIS and Sequences to TiDB — each maps to any object or custom field on the other side. | |
| Namespaces Namespaces partition databases and determine the connection context for integrations. | Databases MySQL-style schemas addressed by any MySQL-compatible client. | Namespaces is specific to InterSystems IRIS and Databases to TiDB — each maps to any object or custom field on the other side. | |
| Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. | Columns MySQL-compatible types mapped to fields in the paired system. | Stored Procedures is specific to InterSystems IRIS and Columns to TiDB — each maps to any object or custom field on the other side. |
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.
DetectionStacksync polls InterSystems IRIS for changes on an incremental schedule, reading only records changed since the previous pass. Polling (timestamp or query-based).
DeliveryEach detected change is applied to TiDB as a row-level write, with types converted between the two schemas.
DetectionChanges in TiDB are captured at the source via change data capture — no polling loop against its API. Log-based CDC via TiCDC, which captures row changes from TiKV and streams them to downstream sinks.
DeliveryEach detected change is applied to InterSystems IRIS as a row-level write, with types converted between the two schemas.
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every InterSystems IRIS–TiDB connection.
Changes in InterSystems IRIS or TiDB instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever InterSystems IRIS 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 InterSystems IRIS or TiDB record.
Track your InterSystems IRIS ⇄ TiDB sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between InterSystems IRIS 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 InterSystems IRIS 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 InterSystems IRIS 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 InterSystems IRIS and TiDB: authenticate both systems, choose the objects to sync (such as InterSystems IRIS's Tables and Views), map fields visually, and changes propagate both ways in milliseconds — no code required.
Change detection on InterSystems IRIS: Polling (timestamp or query-based); no standard webhook surface. On TiDB: Log-based CDC via TiCDC, which captures row changes from TiKV and streams them to downstream sinks; polling also works. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the InterSystems IRIS side: Globals, Namespaces, Stored Procedures, Tables, plus custom fields where InterSystems IRIS exposes them. On the TiDB side: Indexes, Sequences, Databases, Tables. 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 InterSystems IRIS and TiDB: Migration with zero-downtime cutover; Shared reference data between services; Regional or environment copies. When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.
InterSystems IRIS: SQL over JDBC/ODBC, plus object and REST access layers. Authentication: Database credentials. TiDB: MySQL wire protocol (SQL). Authentication: Database credentials (MySQL-compatible username/password). Stacksync manages authentication, retries, and rate limits on both sides.
