What are the differences between TridentTopology and a regular topology in Storm?

TridentTopology is the API in Storm used to build Trident topologies. Trident topologies are advanced abstractions designed to handle streaming data, and are more flexible and user-friendly than regular Storm topologies. TridentTopology offers a range of convenient methods and operators to assist users in constructing the logic for processing streaming data, without the need for extensive knowledge of underlying implementation details.

Compared to a regular Storm topology, TridentTopology offers more operators and abstractions, making it easier to implement common stream processing tasks such as aggregation, filtering, and mapping. TridentTopology also provides advanced features like transactional processing, allowing users to more easily implement complex stream processing logic.

In general, TridentTopology is considered more advanced and flexible compared to a regular Storm topology, making it suitable for handling complex streaming data processing scenarios. However, it also comes with additional learning costs and complexities.
