Why teams connect Apache Cassandra and IBM Informix

Keep Apache Cassandra and IBM Informix 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 Apache Cassandra and IBM Informix 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

  • 01 Sync customer profile data between Cassandra and a CRM so operational apps and sales tools agree.
  • 02 Write attributes computed elsewhere (scores, preferences) back into Cassandra tables serving low-latency reads.
  • 03 Replicate Informix tables into a cloud warehouse using its change data capture interface for near-real-time reporting.
  • 04 Sync sensor and meter readings stored in Informix TimeSeries structures to analytics platforms.

Common sync patterns

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.

Cross-engine sync

Keep the same dataset live in both Apache Cassandra and IBM Informix, so each workload runs on the engine that suits it.

What you can sync between Apache Cassandra and IBM Informix

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.

Apache Cassandra objects IBM Informix objects How this pairing syncs
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Tables Relational tables mapped directly to sync targets. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Stored procedures Server-side logic sometimes invoked as part of write paths. Materialized Views is specific to Apache Cassandra and Stored procedures to IBM Informix — each maps to any object or custom field on the other side.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Logical logs The transaction log that Informix's CDC interface reads committed changes from. Secondary Indexes is specific to Apache Cassandra and Logical logs to IBM Informix — each maps to any object or custom field on the other side.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Databases Top-level containers that scope a sync connection. User-Defined Types is specific to Apache Cassandra and Databases to IBM Informix — each maps to any object or custom field on the other side.
Collections List, set, and map columns handled with type-aware field mapping. Rows The unit of read and write, keyed by primary key. Collections is specific to Apache Cassandra and Rows to IBM Informix — each maps to any object or custom field on the other side.
Counters Increment-only counter columns, usually read-only in syncs. Views Read-only projections used to shape outbound data. Counters is specific to Apache Cassandra and Views to IBM Informix — each maps to any object or custom field on the other side.

How changes propagate between Apache Cassandra and IBM Informix

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.

Apache Cassandra IBM Informix Sub-second propagation

DetectionChanges in Apache Cassandra are captured at the source via change data capture — no polling loop against its API. Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns.

DeliveryEach detected change is applied to IBM Informix as a row-level write, with types converted between the two schemas.

IBM Informix Apache Cassandra Sub-second propagation

DetectionChanges in IBM Informix are captured at the source via change data capture — no polling loop against its API. Informix's Change Data Capture API reading committed changes from logical logs.

DeliveryEach detected change is written to Apache Cassandra through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apache Cassandra: No API quotas; throughput is governed by cluster capacity and consistency-level choices.
  • IBM Informix: Bounded by server resources and session limits rather than an API quota.
