DataGrip 2021.3 Help

Work with data files

Once you have established connection to a server, you can work with the data files. With the Big Data Tools plugin, you can easily perform basic file operations as well as quickly preview large structured files in tabular form.

Filter the list of buckets

  1. For the S3-like servers, you can filter the buckets to preview and work with. You can do it when configuring a new connection, or you can tweak earlier configured connection settings. Select a server in the Big Data Tool tool window and click connection settings on the window toolbar.

  2. In the settings dialog, specify a pattern in the Buckets filter list, then select the way the filter should be applied from the Filter type. If no filter is specified, all buckets will be shown in the Big Data Tool.

    You can also sort data in columns by clicking column headers.

    When you open .parquet files, the plugin only displays the first portion of the file content. This is especially useful when you work with very large files.
