Developed and delivered a Parquet and Arrow import feature for the apache/tsfile repository, enabling seamless data ingestion from both formats into TsFile. The implementation supported user-specified schemas as well as automatic schema inference, reducing manual effort and accelerating the onboarding of new datasets. Leveraging Java along with Apache Arrow and Apache Parquet, the work expanded TsFile’s interoperability with diverse data sources and streamlined data processing workflows. By focusing on flexible data import and export capabilities, the solution addressed the need for efficient integration of heterogeneous datasets, enhancing the repository’s utility for data engineers working with large-scale data processing tasks.
