• Realtime topologies are for taking the xml documents generated from ingestion from various source systems and generate one unified xml document called operational document.
• Query topologies are for querying the MarkLogic documents based on consumer filter criteria.
• All these topologies are combination of different spouts and bolts. Each of these topologies have architecture implemented so that most of the topologies have predefined spouts and bolts. With this implementation ready it is easy to implement a new topology by extending the class and implementing corresponding spouts and bolts methods.
• I have worked on writing various topologies related to the concepts parties, accounts, transactions and agreements.
