Evict from cache
----------------
Key: IBATIS-222
URL: http://issues.apache.org/jira/browse/IBATIS-222
Project: iBatis for Java
Type: New Feature
Components: SQL Maps
Versions: 2.1.6
Reporter: Paul Benedict
I use the cache mainly to keep in memory objects which are very expensive to
create and are retrieved very often throughout the lifetime of my system. These
objects are also updatable and so I need to refresh them when an insert/update
is called.
The current implemention allows a <flushOnExecute> tag to define the methods to
flush, but this is too coarse. I request an enhancement to allow me to evict
only certain objects (specified by primary keys) so that I do not have to flush
the entire cache for a single object update. It is too costly to throw away
1000s of objects just for one update.
Either the cache should be exposed through a method so that the developer can
programtically evict the correct object or some sort of automated process
should do it as such:
<!-- flush the object in the cache having properties id1 & id2 set to the
object just passed into insertArticle -->
<flushOnExecute method="insertArticle" id="{id1,id2}"
I personally prefer having programatic access... at least until IBATIS can do
it all for me :)
