[jira] Commented: (CAMEL-2558) Configurable cache size for ConsumerTemplate and ProducerTemplate

["Claus Ibsen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/activemq/browse/CAMEL-2558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=58670#action_58670 ] 

Claus Ibsen commented on CAMEL-2558:
------------------------------------

Its more work than at first sight.

This would require end users to {{start}} their {{ProducerTemplate}} before use. In fact the javadoc already states this. But currently you could still use it without have started it.
This will enforce better resource management as end users must start/stop those templates.

It now has a getter/setter for {{maximumCacheSize}} so you can use another value than the default of 1000.
You can do this from both Java and Spring XML as <template/> has it as an attribute.

A global option will also be possible on CamelContext so you can configure this for all cache pools.

Also the EIP patterns which uses a ProducerCache will be retrofitted:
- routing slip
- send (to / toAsync / wireTap etc.)
- recipient list

I wonder if they should
- share one global cache
- have their local cache (= as now)
- option in the DSL to set an individual cache size
