One of the top requests in Marvel came from the community asking for better management of daily indexes. “Marvel is too heavy,” we heard a number of times. In the current release, Marvel now has a default retention duration of 7 days. Beyond this period, the indices created by Marvel will be automatically deleted.
There are subscription licenses available that enable configuration of longer and customized retention intervals. Learn more about Elastic’s subscriptions, which also grant access to security, alerting and the new graph plug-in.
Just got an email today about Marvel index retention.
To me this does not sound like a good reason to put an index retention as default in Marvel free and move the retention customization into subscriptions. They can just use Curator to delete whatever indexes they want. I would be very helpful to keep a history of cluster health for more than the default 7 days.
It's kinda odd to see people submitting for such weird requests.
