DataStax Enterprise Analytics
Analytics In Action
DSE Analytics Solo
DSE Analytics Solo datacenters do not store any database or search data, but are strictly used for analytics processing. This helps to dedicate processing power to pure analysis of your real-time applications.
In this example scenario, there is an existing datacenter, DC1 which has existing database data. Create a new DSE Analytics Solo datacenter, DC2, which does not store any data but will perform analytics jobs using the database data from DC1.
DSE Analytics Solo
Add nodes to a new datacenter named DC2, then enable Analytics on those nodes.
Then, configure the dse_leases and dse_analytics keyspaces to replicate to both DC1 and DC2.
DSE Analytics Solo
When submitting Spark applications specify the --master URL with the name or IP address of a node in the DC2 datacenter, and set the spark.cassandra.connection.local_dc configuration option to DC1.
