I have three node dse Cassandra cluster. One node is search enabled, Two node is graph enabled. When I run APIs(which is coded in scala play framework), POST or GET request keeps going and going it does gives a response. There is no any information in logs of Cassandra it is working normally.
Earlier i used to use single node cluster where is graph enabled.
You need to have same workload on all nodes of the same data center, so you need to enable both graph and search on all nodes.
