@HeartSaVioR Thanks for your quick reply.
The reason tuple data is serialized to one field is that the method
`write(List<Object> data, ByteBuffer buffer)` in interface
`IOutputSerializer` serialize a tuple's fields and values to a `ByteBuffer`
object. For this matters, I use one Mongo document field to store it. The sqe
project also do like this.
About 'how to use' document, do you mind if I do this job in a future Jira?
Now I'm working on some other tasks, such as storm-sql-hdfs and etc.
