NanoStreambase Architecture

• “StreamSource” Server (A) sends POST requests to backend server (B)

• JSON is continuously sent from A -> B

• Backend Server (B)

• Server B parses JSON

• Parses JSON into HashMap <key,values>

• Server B runs Vaadin

• Vaadin = Java Front End Framework
• Responds to POST from server A

• Server B runs stream operations

• Processes front end requests from user
• Basic operations: filter, map, union, aggregate, split, merge
• Displays current content of streams to user

• Server B inserts parts of data into in-memory database depending on users’ requests
