Hi,
I am designing a larger system that is composed of several independent smaller
systems (think "services"). Each of the smaller systems has its own
funtionality, logical database, and data access patterns.
My plan is to use a Cassandra cluster as the ("cloud") database solution for
all/most of these systems and I wonder how I should set this up.
The individual system owners should not need to worry about the database beyond
setting up the key spaces they need.
Should I design a single cluster and let the system create and configure their
key spaces as they see fit? Or should I design 2-3 independent clusters
tailored towards certain kinds of access patterns and replication/consistency
needs (focus on read , focus on write, focus on amount of data or simliar) and
then constrain the kinds of key spaces allowed for each cluster kind?
Or should every system be given its own cluster?
Or did I maybe miss another option?
