Per-tenant EPS limits can be set, but any events over the EPS will be dropped from the pipeline; over-license buffering will not be used to handle EPS spikes.

Per-tenant EPS limits can be set if the tenants are defined by event collectors. Then over-license buffering can be used to handle EPS spikes.

If each domain and tenant is defined by log source groups, the EPS limit can be shared by the log source groups used for each tenant. Over-license buffering is defined at the event collector.

The domain sets EPS limits, so each tenant needs to have only one domain. This way, over-license buffering can be used to handle EPS spikes.
