Data retention time

You can set the database retention time as well as the Elasticsearch storage retention time using the Manager service.

When changing these settings, be aware that long retention requires significant disk space. As a rule of thumb, each map-reduce or Spark job requires about 1 MB of disk space; you can store approximately 1000 jobs per 1 GB of disk.
