Subject [jira] [Updated] (CAMEL-6476) StreamCachingStrategy - A better strategy
Date Mon, 22 Jul 2013 09:36:48 GMT

     [ https://issues.apache.org/jira/browse/CAMEL-6476?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Claus Ibsen updated CAMEL-6476:
-------------------------------

    Description: 
The old stream caching has some flaws such as
- copying the existing stream into an internal buffer/type
- spool to disk by default
- a bit confusing to configure
- wrap based
- not exposed in JMX
- not easy to implement custom strategies

Working on a new strategy that supports
- reusing existing stream if it supports marks *done* (added special for byte array input
streams)
- memory based only by default
- threshold for spooling to disk based on memory usage, and payload sizes
- use the internal camel processor to avoid wrapping *done*
- exposed in JMX with runtime stats *done*
- only enabled if explicit turned on *done*
- log at INFO level on startup if enabled and what settings is in use *done*
- configuring in the DSL with a xxxDefinition to make it stand out in the XML DSLs *done*
- configuring of spool directory supporting ENV and JVM system properties *done*
- avoid the leak from CAMEL-6452 *done*
