Re: enable parallel execution

I don't believe parallel execution is supported on the tMySQLInput component. I am not sure why the box is there but greyed out. If you think about it, there aren't many situations where reading in parallel be of any use to you unless you want to parallelize the whole subjob. In which case you can use the tParallelize component. 
Writing is a different matter and that is supported. There are several reasons why you might want to increase the write performance by getting the component to write in parallel. However if data order is important to you, I would be careful with this.

Re: enable parallel execution

Hi Richard
Thank you for the update. Does parallel execution not supported by any of the the database input component(tmsqlinput,toacleinput,tmysqlinput). because i see this option in every component but they are in active.

Re: enable parallel execution

It is not well documented, but I do not believe so.
