how to iterate connection from tJMSInput

Anonymous — Wed, 02 Mar 2016 10:03:38 GMT

Hello.
There's an iterate connection from tJMSInput.
How do I use it?
When I try to connection it to another component, how do I get the messages from it?

Thanks,

Hi,
The "iterate" connection can be used to loop on files contained in a directory, on rows contained in a file or on DB entries.
For more information, please refer to document about: TalendHelpCenter:Connection types
If you want to get the messages from JMS server, the job can be simply designed as: tJMSInput-->main-->tLogrow(tfileoutputxxx)

Best regards
Sabrina

Hi, Sabrina.
If that's the only use of iterate connection, then why are there many components that allow to get this connection from them?
From tJmsInput I'm able to get a main connection and an iterate connection. What's the point of the iterate connection from this component?

Thanks,

Hi,
When you configure an Iterate connection, you are actually enabling parallel iterations.
A parallelization-enabled Iterate connection allows the component that receives threads from the connection to read those threads in parallel.

Here is a document about:TalendHelpCenter:How to launch parallel iterations to read data
