StdoutWriter

#StdoutWriter

Standard Out Writer

This is a basic writer that just prints the list of Results from a Query to System.out (sysout). This makes debugging your Queries a lot easier because you can see what the results look like.

This is an example of the configuration for 3 different queries, writing to StdOut. At the very bottom you can see that numQueryThreads=2 which means that 2 of the queries will be executed concurrently and as soon as one of them is done the final one will execute.
