In Dynatrace Managed we know that we can add multiple servers in the cluster for High Availability in case of disaster of any Data center failover and to sustain High Load.
When it comes to session storage we have one question –
If the session files is stored on the individual servers what happens when that particular server in the cluster goes down due to data center failure then the sessions won’t be available right when one of the servers in the cluster is not available. Please correct me if my understanding is wrong or if it has any steps or documentation to setup for HA of session storage.

Raw transaction data (call stacks, database statements, code-level visibility, etc.) isn't replicated across nodes, it's evenly distributed across all nodes. As a result, in the event of a node failure, Dynatrace can accurately estimate the missing data. This is possible because this data is typically short lived, and the high volume of raw data that Dynatrace collects ensures that each node still has a large enough data set even if a node isn't available for some time.
