Why teams connect BigQuery and InterSystems IRIS

Connect InterSystems IRIS and BigQuery with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want InterSystems IRIS's rows in BigQuery, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in InterSystems IRIS where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in InterSystems IRIS sync into BigQuery in real time, and result tables in BigQuery sync back into InterSystems IRIS, with schema and type mapping between the two systems handled for you.

Common use cases

  • Land CRM and ERP records in BigQuery continuously so dashboards reflect business systems without nightly batch jobs
  • Activate modeled BigQuery tables by syncing computed attributes back into sales and marketing tools
  • Consolidate IRIS data with other databases in an analytics warehouse for cross-system reporting
  • Keep reference data consistent between an IRIS-based clinical or financial application and downstream SaaS tools

Offload heavy reads

Point analytical queries at the synced copy in BigQuery and keep InterSystems IRIS focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from InterSystems IRIS land in BigQuery as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in BigQuery sync into InterSystems IRIS, where whatever reads from that database gets them without querying the warehouse.

What you can sync between BigQuery and InterSystems IRIS

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.

BigQuery objects InterSystems IRIS objects
Tables The syncable unit: only tables can be synced per the Stacksync docs. Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs.
Partitioned tables Synced like regular tables; partition columns map to target fields. Namespaces Namespaces partition databases and determine the connection context for integrations.
Clustered tables Supported; clustering is transparent to the sync. Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations.
Datasets Organizational container — you pick which dataset’s tables to sync. Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs.
Projects Connection scope: the service account grants access per project. Views SQL views expose curated slices of data for outbound replication.
