--- title: Freon date: "2017-09-02T23:58:17-07:00" --- 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 >}} {{< highlight bash >}} *************************************************** Status: Success Git Base Revision: 48aae081e5afacbb3240657556b26c29e61830c3 Number of Volumes created: 10 Number of Buckets created: 100 Number of Keys added: 1000 Ratis replication factor: THREE Ratis replication type: RATIS Average Time spent in volume creation: 00:00:00,035 Average Time spent in bucket creation: 00:00:00,319 Average Time spent in key creation: 00:00:03,659 Average Time spent in key write: 00:00:10,894 Total bytes written: 10240000 Total Execution time: 00:00:16,898 *********************** {{< /highlight >}}
