Data Ingression Engine

Apache Spark, Scala, Apache Kafka, Deltalake


Our client needed a robust system to handle bulk streaming data workloads efficiently. This system extracts data from intricate structures and swiftly transforms it into a simplified format, ensuring quick usability for various purposes. This efficiency enables seamless handling of large data volumes and empowers the client to make data-driven decisions with ease.



  • The client faced the difficulty of handling a continuous stream of large, deeply nested and intricate structured data.
  • Extracting and transforming crucial information from this data into a more manageable form, and ultimately loading it into a datasource.
  • Their existing Java-based Microservices system proved inadequate in terms of speed for processing such enormous data volumes.
  • Difficulty in achieving code adaptability for processing approximately 30 different types of JSONs.
  • Each new JSON type required writing extensive amounts of code, leading to a time-consuming and cumbersome development process.

To overcome these obstacles and cater to client’s evolving needs, they sought a more robust, highly efficient, scalable, and fast fault-tolerant system that could seamlessly handle these diverse data requirements.

Our Solution

  • Developed a Spark-based processing engine that operates seamlessly through a completely metadata-driven configuration. This innovative engine showcases the ability to effortlessly ingest various JSON structures, relying solely on configurational adjustments without necessitating any alterations to the underlying code.
  • Leveraged Spark’s built-in parallel processing capabilities to ensure the fastest possible processing times for substantial data sets.
  • Seamlessly integrated Apache Spark with the existing Apache Kafka data, providing real-time streaming support and fault tolerance features.
  • Leveraged Spark SQL, which closely resembles SQL to simplify Data Transformation process and increase efficiency.
  • Apache Spark’s robust JSON reading methods with schema validation streamlined data transformation from JSON files.
  • Achieved Code Stability by defining transformations through a mapping file, eliminating repetitive coding.
  • Streamlined processes with new mapping sheets for effortless integration of new JSON types.
