Multi-Tenancy in NiFi...

[Kulkarni, Suyog]

How is multi-tenancy implemented in NiFi? Is there any document that I can 
follow for setting this up in our environment? We are running 0.6 version of 
NiFi.

Re: Pooling connection factory for JMSConnectionFactoryProvider

[Oleg Zhurakousky]

Would you mind raising a JIRA as an improvement request and provide all the 
details and we can switch discussion there. I definitely do not want to ignore 
user feedback and experience, so let's discuss it there.

Cheers
Oleg

Oleg,

I see that now.  I was thinking at the service level for the caching
factory to allow more reuse, but am unsure if that would even be a good
idea.

Re: Pooling connection factory for JMSConnectionFactoryProvider

[Oleg Zhurakousky]

Actually it is using caching connection factory (see AbstractJMSProcessor):

private volatile CachingConnectionFactory cachingConnectionFactory;

Can you please provide more details what you are doing and what/where you are 
seeing this?

Cheers

Hello,

I ran into a case of many connections from a nifi instance to an ActiveMQ
hub and thought about pooled/cached connecitons.  I haven't seen any
discussion of adding either a new service for pooled/cached connections or
adding it to the current JMSConnectionFactoryProvider, via either
ActiveMQ's PooledConnectionFactory or Springs CachingConnectionFactory, for
reuse of connections, producers and sessions between processors.

I would like to work on this and was hoping to get suggestions about how to
best approach it.

Pooling connection factory for JMSConnectionFactoryProvider

[Chad Zobrisky]

Hello,

I ran into a case of many connections from a nifi instance to an ActiveMQ
hub and thought about pooled/cached connecitons.  I haven't seen any
discussion of adding either a new service for pooled/cached connections or
adding it to the current JMSConnectionFactoryProvider, via either
ActiveMQ's PooledConnectionFactory or Springs CachingConnectionFactory, for
reuse of connections, producers and sessions between processors.

I would like to work on this and was hoping to get suggestions about how to
best approach it.

Thanks,
Chad
