Question regarding one work floww to one producer about json-data-generator

[andrewserff]

If I understand correctly, there isn't a way to do this currently. You would just need to make separate simulation configs with only one producer.

Thanks Andrew,as you said to make separate configs,how can we do multiple config files that and how we run those multiple config files

[andrewserff]

Just pass the name of the config when you start it. If you need them running at the same time, you would have to run separate instances of the generator, passing different configs to each one.

i have changed the sim config file like this and changed the code to run the multiple workflows to multiple producers simultaneously
{
"workflows": [{
"workflowName": "Harsha",
"workflowFilename": "newWorkflow2.json",
"producers": [{
"type": "logger"
}]
},
{
"workflowName": "Harsha",
"workflowFilename": "newWorkflow.json",
"producers": [{
"type": "logger"
}]
}]
}

after running generator, records randomly generated for some time suddenly one of the threads stopping by the exception

some times generator not able to pick the random value from the json and getting null pointer exception too

[andrewserff]

Your sim config is invalid. You can only have one in the file (needs to be valid json). Put them in two separate files (simConfig1.json, simConfig2.json). As for the exceptions, I guess I'd need to see the workflow configs. I've never seen that happen. Are you passing a very large number into an integer() in your conifg as a max value? and what is the NPE you are seeing?

workflow.txt

this is the work flow iam using

[sriharshamutnuru]

Iam getting NPE for the any one of the keys in the workflow not one specifically

@sriharshamutnuru Please, check out the new version. I've fixed issues like this:

org.apache.commons.math3.exception.NumberIsTooLargeException: lower bound (0) must be strictly less than upper bound (-1)

[andrewserff]

Closing based on lack of activity. If there is still an issue, please let me know.
