bulk workflow variable read using rungimeService

Hi,I would like to read all the process variables in one query. Right now, i am using runtimeService.getVariable() which runs a query for each process instance id. This is too expensive for my application's performance.is there a way i can read a particular variable from a bunch of processes in on

For this purpose it's better to use the HistoricVariableInstanceQuery. There you can query on all instances of a variables across tasks and processes.

Best regards,

Hi,

I would like the runtime variables and not Historic ones. Also, i am using Activiti 5.10 and it does not have this class. Any other alternative?

Thanks,
Raj

Historic variables also contain the runtime variables so that would make no difference. But in 5.10 this wasn't available yet.
Instead you can use the HistoricDetailQuery in a similar way and that should be available in 5.10.

Best regards,
