Concurrent Workflows
Many times we will
have a same set of data we are receiving
from multiple sources and different times and we have to wait to complete one
workflow to start another load .during
these kind of scenarios to decrease the
completion time of data processing
we can use the feature of workflows which allow us to start multiple instances
of the same workflow with same set of data or we can have different paramet
files for each unique instances to load different type of data .
Example :
Here I am loading the file having around 1 year of data for
share prices for NYSE .
And mapping will be as simple as below .
The setting /properties which really matters are for
workflow so after creating workflow I will come to the properties where I have
to set the concurrency properties
As we cane see After selecting edit from workflow menu I get
the pop up where I enabled the concurrency and configured 4 instances with same name , we can select second option
and can give names and also provide parameter file as well .
Lets run the workflow by clicking advance run option .
I have select all instances to run .
After clicking ok all instances will start simultaneously
Thasts all
Next will be using
different instances with paramter files .
