Working at DataSift, I speak to many different clients and discuss their use cases regarding what type of data they would like to filter on, and include within their real-time data streams. I thought it would be useful to start capturing many of the common use cases in a single post and explain how these translate in to Curated Stream Definition Language (CSDL). If you are new to DataSift and or CSDL, the DataSift documentation is great and growing all the time, and this post should give some useful examples.
I will be adding to this post as and when I capture new examples. Please feel free to submit your own if you feel they will be beneficial to others.
