Real-Time Data Processing

Data Observability for Real-Time Data Processing

Real time data processing becomes reliable when the data itself is observable. DS Stream builds event-driven pipelines on Kafka, Kinesis or Pub/Sub with Flink or Spark Structured Streaming, then adds freshness, volume, schema-drift and distribution checks, end-to-end lineage and SLO-based alerting. First observable pipeline in production in 6-8 weeks.

Key takeaways

  • Data observability for real-time data processing is the continuous measurement of freshness, volume, schema, distribution and lineage across every stream and sink.
  • Streaming pipelines rarely fail because of the engine; they fail because observability standards, lineage, schema contracts and SLOs are missing.
  • DS Stream delivers event-driven ingestion on AWS, GCP or Azure with Kafka, Kinesis or Pub/Sub, and stream processing with Flink, Spark Structured Streaming and Beam.
  • Typical delivery is 6-8 weeks from source access to an observable streaming data pipeline in production, with SLOs, alerting and runbooks.
  • Hot-path and cold-path architectures run side by side: sub-second dashboards and activation, plus governed data in Snowflake, BigQuery or Databricks for historical analytics and ML training.

Why do real-time data pipelines fail silently in production?

Most organisations already run streaming workloads but hear about broken pipelines from business users, not from monitoring. The cause is rarely the engine. It is missing observability standards, lineage, schema contracts and SLOs across the real time data processing stack. When a topic stalls or a schema shifts, dashboards, ML models and customer journeys degrade without warning.

  • Silent data loss - streaming pipelines run with no freshness or volume SLOs.
  • Schema drift - breaks downstream real time data analytics tools and ML features.
  • No end-to-end lineage - from the source event to the real-time customer data platform.
  • Latency spikes under load - no per-stage tracing in the streaming data pipeline architecture.
  • Fragmented integration - real time data integration tools with no shared alerting or ownership.
  • Reactive firefighting - business users detect issues before engineers do.

What is data observability in real time data processing?

Data observability is the continuous measurement of data health across streaming pipelines: freshness, volume, schema, distribution and lineage. In real-time data processing it detects stalled topics, schema drift or missing events within seconds, before they corrupt downstream analytics, ML models or customer-facing experiences. Alerting is tied to business SLOs, not infrastructure noise.

How it is implemented:

  • Observability agents instrument topics, processors and tables, so monitoring follows the data rather than a single component.
  • Checks run across every stream and sink, not only at ingestion.
  • Lineage is traced end to end, from the source event through processing to the warehouse, CDP or feature store.
  • SLIs and SLOs for latency, freshness and completeness are defined per pipeline and wired into dashboards and on-call rotations.

Who is this real time data processing service for?

It is for data and engineering leaders who need streaming data to become a governed, observable asset: CDOs and Heads of Data & AI, Heads of Data Platform or streaming leads, CTOs and VPs of Engineering, lead and staff data engineers, and Heads of Analytics or Martech who depend on a reliable real-time customer data platform feed.

  • CDO / Head of Data & AI - needs streaming data feeding analytics, ML and customer-facing products instead of a fragile set of point integrations.
  • Head of Data Platform / streaming lead - needs standardised architecture, reusable observability and clear SLOs so teams ship real-time use cases without reinventing the foundation.
  • CTO / VP Engineering - needs to modernise real-time data integration across the estate with a platform that scales, meets compliance and supports real-time customer journey orchestration.
  • Lead and staff data engineers - need strong practices for schema contracts, testing, lineage, exactly-once processing and latency tuning.
  • Head of Analytics / Martech - needs activation, personalisation and reporting to reflect what is happening right now.
What we deliver

Architecture and technical building blocks

We cover the full streaming stack: pipeline engineering, observability, customer data platform enablement, big data analytics integration, and platform reliability with measurable SLOs.

Streaming data pipeline engineering

  • Event-driven pipelines on Kafka, Kinesis or Pub/Sub
  • Stream processors such as Flink and Spark Structured Streaming
  • Schema contracts, dead-letter queues and exactly-once semantics where required
  • Defined latency and freshness SLOs for every pipeline

Data observability for streaming

  • Freshness, volume, schema, distribution and lineage checks across every stream and sink
  • Observability agents instrumenting topics, processors and tables
  • Continuous real time data monitoring
  • Alerting tied to business SLOs instead of infrastructure noise

Real-time customer data platform

  • Event collection and identity resolution
  • Feature computation and activation into marketing, product and support tools
  • Real-time customer journey orchestration with sub-second decisioning

Big data analytics and integration

  • Streaming data integrated with warehouses and lakehouses: Snowflake, BigQuery, Databricks
  • Hot paths for dashboards combined with cold paths for historical models
  • Integration governed via contracts, CDC patterns and validated connectors

Platform reliability and SLOs

  • SLIs and SLOs for latency, freshness and completeness per pipeline
  • Dashboards with alerting connected to on-call rotations
  • A clear contract with business stakeholders on what real time means for each use case

How it works: from discovery to an observable streaming pipeline

Five steps take you from source access to a live pipeline under defined SLOs, typically in 6-8 weeks.

  1. Discovery and architecture (1-2 weeks)

    We map source systems, event volumes, latency targets, compliance constraints and consumer use cases. Output: target architecture, SLIs and SLOs per stream, and an observability blueprint.

  2. Foundation build (2-3 weeks)

    We provision brokers, stream processors, a schema registry and the observability layer on your cloud. Output: a running platform with base monitoring, lineage and CI/CD for streaming jobs.

  3. Pipeline implementation (2-3 weeks)

    We implement the first production pipelines with schema contracts, transformations, dead-letter queues and freshness checks. Output: governed streaming data flowing to your warehouse, CDP or analytics tools.

  4. MVP go-live (6-8 weeks total)

    We cut over the first business use case, whether real-time dashboards, CDP activation or ML features, under defined SLOs. Output: a live pipeline with observability, alerting and runbooks.

  5. Run and scale

    We provide SLA-based support, onboard new streams, tune performance and transfer ownership. Output: a platform with documented standards and enabled internal teams.

Frequently asked questions

Which streaming data pipeline architecture do you recommend?

It depends on workload and cloud. For most clients we deploy Kafka or Kinesis as the event broker, Flink or Spark Structured Streaming for stateful processing, a schema registry for contracts, and a dedicated observability layer. Sinks usually include a warehouse such as Snowflake, BigQuery or Databricks, plus operational stores like a CDP or feature store.

Can you build a real-time customer data platform on our existing stack?

Yes. We build real-time customer data platform capabilities on top of your existing cloud and event infrastructure rather than forcing a vendor swap. We add identity resolution, event unification, segment computation and activation connectors, with observability and lineage across the full flow.

How long does it take to reach production?

Typically 6-8 weeks from source access to the first production streaming pipeline with SLOs, observability and at least one activated use case. Complex enterprise integrations or strict compliance environments can extend this to 10-12 weeks.

What real time data integration tools do you work with?

We work with Kafka Connect, Debezium, Fivetran HVR, Confluent, Estuary, Striim and native cloud services such as Kinesis, Pub/Sub and Event Hubs. Tool choice follows the architecture, not the other way around: we select integration tools that fit your latency, compliance and operating model.

Do you support both hot-path and cold-path real time big data analytics?

Yes. We implement dual-path architectures where the hot path powers sub-second dashboards, alerting and activation, while the cold path lands governed data in the warehouse or lakehouse for historical analytics and ML training, with consistent schemas across both paths.
