Abstract:
A first request is received from a first processing node to produce data blocks of a first data stream representing a first communication topic. The first processing node is one of the processing nodes handling a specific function. Each of the processing nodes is executed within a specific node container having a specific operating environment. A global memory segment is allocated from a global memory to store the data blocks of the first data stream. A first local memory segment is mapped to the global memory segment. The first local memory segment is allocated from a first local memory of a first node container containing the first processing node. The first processing node directly accesses the data blocks of the first data stream stored in the global memory segment by accessing the mapped first local memory segment within the first node container.
