abstract class TopologyTransactionProcessorCommonImpl[M] extends TopologyTransactionProcessorCommon
Main incoming topology transaction validation and processing
The topology transaction processor is subscribed to the event stream and processes the domain topology transactions sent via the sequencer.
It validates and then computes the updates to the data store in order to be able to represent the topology state at any point in time.
The processor works together with the StoreBasedDomainTopologyClient
