title: Running a website/web application that analyzes big data
body: <p>Hello i have this website where the server has in its database 2-3 GB of data and i want the user to run a query to get the data and analyze it (for example the user can put age>15) and then press the button that says cluster to do clustering in that data , then the user sees that with libraries like d3.js.</p>
