+Database configuration
+======================
+CPS uses PostgreSQL database. As per the `PostgreSQL documentation on resource consumption
+<https://www.postgresql.org/docs/current/runtime-config-resource.html#GUC-SHARED-BUFFERS>`_, the *shared_buffers*
+parameter should be set between 25% and 40% of total memory. It has a default value of 128 megabytes, so this should be
+set appropriately. For example, given a database with 2GB of memory, 512MB is a recommended value.

+============================================
+
+CPS-Core and NCMP both internally uses embedded distributed datastructure to replicate the state across various instances for low latency.
+These instances require some additional ports to be available. The default range starts from 5701 and based on the number of instances configured they are incremented sequentially.
+
+Below are the list of distributed datastructures that we have.
