Tuning transactor memory in Datomic Cloud

The on-prem version allows to tune the transactor memory. Is this also possible in the cloud version?

I am particular interested in increasing the indexing performance which causes a lot of :cognitect.anomalies/busy.

Instance memory settings are not configurable in Datomic Cloud in the same way as they are in Datomic On-Prem.

We recently enabled the use of i3.xlarge instances for the primary compute group, which should provide additional computational and memory resources for systems that require them.

Thank you for the clarification.
