Sizing - User Replay (db sizing estimates)


In case you have not enabled the User Replay feature, note that it requires significant additional database storage (there is no free lunch! 🙂) and that additional DB storage very much depends on the 1)technology (e.g. AngularJS, WordPress,, Siebel CRM, etc) 2)version of the technology 3)customization built in the technology (when that applies) 4) user activity on the technology/app 5)settings of the User Replay feature. 

Here are some indications of what a db storage looks like for two out-of-the-box Oracle Siebel CRM:
