> Add support for stream data to filesystem when using BlobMessages
> -----------------------------------------------------------------
>
> Key: AMQ-3017
> URL: https://issues.apache.org/activemq/browse/AMQ-3017
> Project: ActiveMQ
> Issue Type: New Feature
> Components: Broker
> Reporter: Norman Maurer
> Assignee: Dejan Bosanac
> Attachments: AMQ-3017-v2.diff, AMQ-3017.diff
>
>
> Using BlobMessages can help to reduce the memory usage very much when you
> have the need to transfer many big messages via activemq. However for this
> you need some kind of storage which can be used to transfer the payload to.
> ActiveMQ can handle the transfer with FTP and HTTP at the moment. However if
> you only run an embed ActiveMQ broker this is often overkill and just plain
> slow. Here it would be cool to just stream the payload from and to the
> filesystem, to get the memory improvement when using BlobMessages but keep
> the complex level low + have high speed.
