How many parallel workflows we can process with the configured datastore in Cassandra ?
Cassandra retention period and durability.

Thank you

It is mostly bound by the size of workflow histories and disk size Cassandra uses as well as for how long closed workflows are kept (retention period). In the most practical cases, the size of the cluster is defined by how many actions per second need to be executed, not by the number of workflows.

I believe that it should be no problem to support trillions of workflows if they are passively waiting most of the time. We tested with hundreds of millions, but these workflows were relatively active.
