Distributed Cache for ProcessDefinitionInfoCache

Flowable Engine
#1

Hi,

Is it possible to use a distributed cache for ProcessDefinitionInfoCache?
I read Joram Barrez’s blog about using distributed cache as process definition cache, but unlike ProcessDefinitionCache, ProcessDefinitionInfoCache cannot be configured via ProcessEngineConfigurationImpl.

If not, is it okay if we would implement a custom distributed cache extending ProcessDefinitionInfoCache and pass it to the DeploymentManager as ProcessDefinitionInfoCache?

Regards,
Mohammad

Hey Mohammad,

If you implement your own extension, I don’t see why it won’t be possible.

ProcessDefinitionInfoCache cannot be configured via ProcessEngineConfigurationImpl.

This is clearly an oversight and a setter can be added to the ProcessEngineConfigurationImpl so you can set a custom ProcessDefinitionInfoCache in the configuration. You can provide a PR that we can review and merge within the engine. As you have noticed you can also pass it directly to the DeploymentManager.

Cheers,
Filip

Hey Filip,

Thanks for your quick reply.

Yeah, I just wanted to double check so that that wouldn’t cause unintended consequences.

Great! I’ll do it and hope to see it in next releases :wink:
