Pega High Availability
How Pega handle the high availability. i.e. I have 3 nodes having DDS ( Cassandra ). i run some job and the first DDS node was used for job processing. Somehow that node goes down and job is failed in that node.
Will there be no automatica failover . Job moved to another remaining cassandra node?
how that will be handled. How pega platform Application level failure will be handled in case any issue with node type

When you say job ? What kind of functionality you are expecting to run DDS nodes ?
When you say DDS (Cassandra) ? Are you referring to External Cassandra or embedded cassandra ?
DDS nodes are usually used to store the Data to embedded cassandra which is shipped as part of pega platform.
You can can use the multi datacenters setup for the cassandra cluster for backup and high availability.
