About JSON to Parquet Conversion
This tool allows you to convert JSON (JavaScript Object Notation) data into the Apache Parquet format. Parquet is a columnar storage format available to any project in the Hadoop ecosystem, regardless of the choice of data processing framework, data model or programming language.
Columnar Storage
Parquet stores data by column rather than by row, which allows for better compression and faster queries when accessing specific fields.
Type Safety
Parquet enforces a schema, ensuring data consistency and type safety, unlike the flexible nature of JSON.
