Streamliner is an open source tool that allows developers to build real-time data pipelines using Apache Spark, integrating data streaming from various sources into SingleStore for persistence and application serving. With minimal code required, users can instantly create their pipelines, performing data transformations and loading data directly within the Ops web UI or by uploading custom Extractor and Transformer classes. Streamliner supports complex operations on data, enabling real-time manipulation of data before inserting it into SingleStore. The tool is great for developers and data scientists looking to easily pre-process data while leveraging Spark's power, with examples and documentation available in the Streamliner repository and SingleStore documentation.
