To get the ball rolling and give detailed information on how to do some cool stuff with Pipeline Designer, I have written a series of blogs on this subject. I have used Pipeline Designer to take Twitter data and produce a heatmap with this data to show where people are tweeting from. There are a number of blogs going through each step in the process, from dealing with Apache Avro, using Talend Routes to collect the data and finally processing the data with Pipeline Designer. Feel free to ask any questions and I will keep an eye on this thread.
