Migration of Spring Boot ETL App from MongoDB to Cassandra+Apache Storm

Hello, This might really be painful migration. The reason of Cassandra, although being very reliable and probably write-fast, gives very very less flexibility as far as schema is concerned. So please let me now the schema, and then i might be able to tell you exact things related to its portability. May i know how complex is the REST api and why do you think Apache Storm is the best solution? Let me know please ~-~-~-~-~-~- About us ~-~-~-~-~-~- I am Zeeshan, and for most part of last 12 years working over C++(Windows and Mac desktop), Node.JS/PHP/Python (Web and API), Swift/ObjC(iOS) and Java/Kotlin(Android).
