Why teams connect IBM Db2 and MongoDB

Keep IBM Db2 and MongoDB 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 IBM Db2 and MongoDB 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

  • Expose Db2 records that back core business systems to a CRM so sales and support see order or account state.
  • Sync SaaS data into Db2 tables that existing enterprise applications and reports already consume.
  • Sync MongoDB collections with a CRM so customer documents written by the application appear as CRM records, and CRM edits flow back as document updates.
  • Replicate operational MongoDB data into a relational database, flattening nested documents into normalized tables for SQL reporting.

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.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

What you can sync between IBM Db2 and MongoDB

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.

IBM Db2 objects MongoDB objects
Databases The connection target; each database holds the schemas a sync addresses. Indexes Keep lookups by sync key fast on large collections.
Schemas Namespaces separating synced data from application and system objects. Views Read-only aggregation-defined sources for filtered sync datasets.
Tables Primary read/write target for syncing rows with SaaS systems or other databases. Change streams The oplog-backed event feed that powers real-time change capture.
Views Read-only projections often used to expose curated slices to a sync. GridFS files Chunked file storage whose metadata can be referenced by synced documents.
Indexes Support fast key lookups on sync match columns. Databases Logical groupings of collections that scope a sync connection.
Stored Procedures Existing business logic sometimes invoked as part of write paths. Collections The table-like sync unit; each collection maps to a table or object in the paired system.

How the IBM Db2 and MongoDB connectors work

IBM Db2

Integration surface
SQL via JDBC/ODBC/CLI drivers; optional REST endpoints in some editions
Authentication
Database credentials, typically backed by OS or LDAP authentication
Change detection
Log-based CDC through IBM's replication tooling where licensed; otherwise polling on timestamp or audit columns
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by instance resources and workload management settings

MongoDB

Integration surface
MongoDB wire protocol via official drivers; Atlas additionally offers an administration REST API for cluster management
Authentication
Database credentials (username/password) or TLS/SSL X.509 certificate (.pem upload), entered individually or via a MongoDB connection string (SRV or standard); Stacksync IP allowlisting required
Change detection
MongoDB oplog and change streams (requires the database to run as a replica set — even single-node); Stacksync leverages these built-in tools to track changes in real time
Capabilities
read · write · CDC
