Terracotta 10.15 | Terracotta Server Administration Guide | Importing and Exporting Datasets | Overview
 
Overview
Dataset records and their cells can be exported to file in both Apache Parquet format and TSON format. Records and cells can also be imported into a dataset from a TSON file. This import-export capability is provided through both a command-line utility and a TCStore API via libraries and scripts that are distributed with the kit.
Parquet is a commonly used, open source, column-oriented, binary data format designed for efficient data storage and retrieval. As a binary format, Parquet files are consumed by software systems, which in turn target other storage systems and formats.
The TSON format is a kind of typed JSON where each data value is described with a type declaration wherever it appears within the body of the file.
