Export tool

The export tool allows you to export data from a topic into various binary files. When you open the export tool and have chosen a topic to export, there are several things you must do before exporting can be successful.

• Choose the destination directory - find a suitable directory for the exported files to be stored in
• The format of the key file name pattern - choose whether or not you want to export key data, and in what format the file names will be stored as
• The format of the value file name pattern - choose whether or not you want to export value data, and in what format the file names will be stored as
• Number of messages - choose the number of messages per partition you want to export, and decide if you want to export the first N messages or the last N messages
• Partitions - choose which partitions in the topic you want to include in exporting

Once this information has been filled out, you are able to export by clicking the "Next" button on the bottom toolbar. The results screen will show the time it took to export the messages, and the number of messages that were exported (in total and per partition). Additional information about the messages are also included, such as bytes used for key data and bytes used for value data per partition.

Import tool

The import tool allows you to import data into a topic. After selecting a topic to import the data into, there are a few things you must do before importing can be successful.

• Source directory - either manually enter the folder with the data you are importing, or navigate to it by selecting the folder icon.
• The format of the key file name pattern - choose whether or not you want to import key data, and in what format the key data has been stored
• The format of the value file name pattern - choose whether or not you want to import value data, and in what format the value data has been stored
• Partitions - choose which partition(s) in the topic you want the data to be imported into

Once this information has been filled out, you are able to import by clicking the "Next" button on the bottom toolbar. The results screen will show the time it took to import the messages, and the amount of messages that were imported (in total and per partition). Additional information about the messages are also included, such as bytes used for key data and bytes used for value data per partition.
