I have a standart Datastax DSE cluster with 2 DCs (DC_DSE1 and DC_DSE2).
I have also in each DC an Analytic solo DSE for spark purpose attached to the Ring of the DSE mentioned above (DC_ANALYTIC_DSE1 and DC_ANALYTIC_DSE2).
I will not replicate of course the applicative Keyspaces with analytics one.
Which Keyspaces should I replicate between the Four DC? those one?
