Real-Time Data Ingestion &
CDC Architecture Landscape
A vendor-neutral view on the shift from batch to streaming, Iceberg adoption, and the strategic decisions C-level leaders must get right.
Where Is the Money Flowing?
The fastest-growing part of the data platform market is no longer storage or dashboards. It is the ingestion layer that keeps analytical, operational and AI systems in sync with reality. Investment is moving from one-off ETL projects to continuous, governed ingestion platforms that combine log-based CDC, streaming and open table formats like Iceberg.
The Content Gap
Most public content is either vendor marketing or tool-centric “best CDC tools” lists. What is missing is an architecture-first view: how these tools actually wire into data platforms and where real-time deployments fail in practice.
For a C-level leader, the core question is no longer “Which connector should we buy?” but “What ingestion architecture do we standardize on for the next 5–10 years?”.
The Ingestion Landscape 2026
Log-Based CDC
Reads database logs (WAL/redo) to capture every change with minimal impact. High fidelity, low latency.
- Debezium
- Oracle GoldenGate
- HVR / Qlik Replicate
- Cloud-native CDC services
Managed Ingestion Services
“Connector as a Service” platforms handling scheduling and schema drift. Fastest time-to-value.
- Fivetran
- Airbyte Cloud
- Confluent Cloud Connect
- Snowpipe Streaming
Streaming-Native Ingestion
Programmable pipelines using stream processors. Highest flexibility and scalability.
- Kafka / Redpanda producers
- Kafka Connect (Custom)
- Apache Flink pipelines
- Stream-first microservices
The New Reference Architecture
The classic “nightly batch” pattern is being replaced by a 5-layer real-time stack: change capture, transport, processing, storage and serving.

CDC vs. Managed Connectors vs. Streaming
| Dimension | Log-Based CDC | Managed Ingestion | Streaming-Native |
|---|---|---|---|
| Latency | Seconds | Minutes | Sub-second |
| Source Impact | Low | Medium | Varies |
| Transparency | High | Low (Black box) | High |
| Effort | Medium | Low | High |
Strategic SWOT Analysis
- Fresher data for AI & Decisions.
- Reduced batch window pressure.
- “Time Travel” replay capabilities.
- Operational complexity (offsets, retries).
- Schema evolution pain.
- Continuous compute costs.
- Consolidation of pipelines.
- Unified Data Contracts.
- Real-time business observability.
- Vendor lock-in (Proprietary formats).
- Opaque SaaS failures.
- Talent shortage in streaming.
C-Level Decision Checklist
Assign ownership and KPIs.
Make schemas explicit.
Consolidate onto strategic platforms.
Build internal expertise.
Future Outlook
By 2026, event-driven ingestion will be the default. Organizations that treat ingestion and contracts as products will have a sustainable advantage in shipping reliable AI features.
