Apache Spark

Apache Spark development and optimisation

We write and tune Spark jobs for large-scale transformation, streaming and machine learning, on Databricks, EMR, Dataproc or your own clusters.

  • PySpark and Spark SQL development
  • Structured Streaming pipelines
  • Job tuning for runtime and cost
  • Migration from legacy Hadoop jobs

Spark work we take on

ETL jobs

Readable, tested PySpark or Scala code for heavy transformations.

Streaming

Event processing from Kafka, Kinesis or Event Hubs with exactly-once sinks where needed.

Optimisation

Fixing skew, shuffles and small-file problems that slow jobs down.

ML pipelines

Feature preparation and model training with Spark MLlib or integrated libraries.

How an analytics engagement runs

  1. Step 1

    Questions first

    We agree the decisions the data should support and the measures that matter.

  2. Step 2

    Data review

    We profile your sources, note quality issues and confirm what is feasible.

  3. Step 3

    Build in slices

    Pipelines, models and reports are delivered one subject area at a time.

  4. Step 4

    Hand over

    Documentation, access controls and training so your team can run and extend it.

Frequently asked questions

Databricks or open-source Spark?

Databricks reduces operational work; self-managed Spark can cost less at steady scale. We compare both for your team.

Can you work with the tools we already pay for?

Yes. We usually build on your existing cloud, warehouse and BI licences, and recommend new tools only when there is a clear gap.
