Huge increase in Oplog GB/h

over the last week-end we saw the Oplog GB/h going from ~30MB/h to over 2GB/h in 24h. This caused some disk space issues and then changed the cluster’s tier from M10 to M20.
We do not understand why this Oplog rate increased to drastically, any idea what could trigger such a Oplog rate ?
Thanks for your help,

Hi @Luc_Juggery - Welcome to the community.

If you’re certain there were no other changes on the application side I would advise contacting the Atlas in-app chat support team regarding this as they further insight into your cluster.
