Retention rules

Retention rules

Rules are used to removing retention data from data base once a day. Which data will be deleted shows directly retention rules. For example retention rule with dataType=EVENT and maximumAge=30 removes from system all events older than 30 days.
The Retention rules interface consists of parts:

• The retention rule collection resource retrieves retention rules, accesible by url /retention/retentions
• The retention rule resource represents individual retention rule that can be view, accesible by url /retetion/retentions/{retentionRuleId}
