Export tool

The export tool allows you to export data from a topic into various binary files. When you open the export tool and choose a topic to export, there are several things you must configure before the export can succeed.

• Choose the destination directory - find a suitable directory in which to store the exported files
• Choose the format of the key file name pattern - decide whether you want to export key data, and how the file names should be generated
• Choose the format of the value file name pattern - decide whether you want to export value data, and how the file names should be generated
• Choose the number of messages - decide how many messages per partition you want to export, and whether you want to export the first N messages or the last N messages
• Choose the partitions - decide which partitions in the topic you want to include in the export

Once this information has been filled in, you can 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 is also included, such as the bytes used for key data and the 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 data into, there are a few things you must configure before the import can succeed.

• Source directory - either enter the folder that contains the data you are importing, or navigate to it by selecting the folder icon
• Choose the format of the key file name pattern - decide whether you want to import key data, and in which format the key data has been stored
• Choose the format of the value file name pattern - decide whether you want to import value data, and in which format the value data has been stored
• Choose the partitions - decide which partition(s) in the topic you want the data to be imported into

Once this information has been filled in, you can 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 number of messages that were imported (in total and per partition). Additional information is also included, such as the bytes used for key data and the bytes used for value data per partition.
