Summary
We can store a lot of data and run MapReduce on them to analyze the data. We can also set up Hadoop in such a manner that it does not impact the transactional part of Cassandra in a negative way. We know how to set up Pig for those who want to quickly assemble an analysis instead of writing lengthy Java code. We can also power Solr searches by Cassandra, making Solr more scalable than it already is.
With a plethora of analytical tooling available in the market, you may or may not choose Cassandra. Maybe you could perform stream analysis, which does not require data to be stored and analyzed later; for example, if you decide to apply multiple operations on live streaming tweets and show the result immediately, you would like to use a tool such as Twitter Storm. Although there is no specific project that could guide you on how to do this, it is pretty simple to configure Twitter as Storm Spout. This will emit the tweet stream to the next Bolt and get it processed and forwarded to the...
