             Summary: StreamCachingStrategy - A better strategy
                 Key: CAMEL-6476
                 URL: https://issues.apache.org/jira/browse/CAMEL-6476
             Project: Camel
          Issue Type: New Feature
          Components: camel-core
            Reporter: Claus Ibsen
            Assignee: Claus Ibsen
             Fix For: 2.12.0


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
- 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
- exposed in JMX with runtime stats
- only enabled if explicit turned on
- log at INFO level on startup if enabled and what settings is in use
- configuring in the DSL with a xxxDefinition to make it stand out in the XML DSLs
