Disable persistence of large variables?

[steeqs4]

I have a synchronous process that invokes one web service to obtain a large file, then invokes another web service, passing in the large file.

ODE very happily persists the file to the database - more than once, in fact.

So I have two problems - one, the database size increases very rapidly, and two, the process is very slow.

As far as I'm concerned if the process dies mid-way I don't want to re-try later. I don't want ODE to resubmit. I don't want ODE to save the large variable. Can I configure ODE the way I need it to work?

Thanks, Martin

Hi Martin,

As far as I know, I don't think we have the mechanism of disabling persistence of large variables. You can file a request task in our jira system if you want.

One option may be to use an 'in-memory' process - see http://ode.apache.org/user-guide.html#UserGuide-Inmemoryexecution

However note the restriction - it only works if the process has a single receive, so effectively the process receives the message, does some work, and then completes. In this situation they don't use persistence.

From the description of your task, it sounds like this is a possibility, if the process receives a message, asks web service 1 for the large file, then upon receipt immediately sends it on to the next web service 2.

Might be worth a try.

Thanks Gary, that works for me - I can live with those constraints. The database did not increase appreciably even after sending through a 20MB file.
