Overview

Freon is a load-generator for Ozone. This tool is used for testing the functionality of ozone.

Random keys

In randomkeys mode, the data written into ozone cluster is randomly generated. Each key will be of size 10 KB.

The number of volumes/buckets/keys can be configured. The replication type and factor (eg. replicate with ratis to 3 nodes) Also can be configured.

For more information use

bin/ozone freon --help

Example

{{< highlight bash >}} ozone freon randomkeys --numOfVolumes=10 --numOfBuckets 10 --numOfKeys 10 --replicationType=RATIS --factor=THREE {{< /highlight >}}
