1.) Graceful handles back-pressure build up. 2.)Distributed and fault tolerant. 2.) Performs real-time data processing seamless because of it's stateless nature.
1.) Resource intensive: Needs significant amount of computational resources , which incur cost and maintenance. 2.) Storm SQL is not as matured as other SQL-like APIs. 3.) Lack of In-Built storage: To persist data or intermediate results, needs to integrate storm with external databases.
