title: Storage in Apache Flink
body: <p>After processing those millions of events/data, where is the best place to storage the information to say that worth to save millions of events? I saw a <a href="https://github.com/apache/flink/pull/287" rel="nofollow">pull request</a> closed <a href="https://github.com/apache/flink/commit/ba7a19c10df9f2abb5fe9828e57f46a49cbcfd18" rel="nofollow">by this commit</a> mentioning Parquet formats, but, the default is the HDFS? My concern is after saving (where?) if it is easy (fast!) to retrieved that data?</p>
