Bricata data nodes enable you to increase your metadata retention in a modular way by allowing you to add new data nodes into your cluster that auto-scale your back end data storage. This modular capability should be tied to your own observation of the volume of data you are generating, and the Instance size you are choosing to best meet your systems needs. Please do contact Bricata support for help in finding the ideal instance sizing and retention timelines for your circumstance. Contact support at this url: https://bricata.com/techsupport/
