Hello all.
I have finished my work with the eviction code in Infinispan, here is a
summary of what has happened.
From a user perspective (including API and configuration) as well as a
design overview, please have a look at
http://www.jboss.org/community/docs/DOC-13449
Comment about the config, seeing as expiration is tighly linked to
eviction, wouldn't it make more sense for expiration to be a subelement
of eviction? i.e.
<eviction strategy="FIFO" wakeupInterval="1000"
maxEntries="2000">
<expiration lifespan="1000" maxIdle="500" />
</eviction>
I suppose expiration element attributes are not part of eviction element
since they're primarily an optional feature and maxEntries is the main
config option?
From an implementation perspective, have a look at the srcs of
FIFODataContainer and LRUDataContainer. These two classes are where
everything happens. The javadocs should explain the details, but in a
nutshell you can expect constant time operations for all puts, gets,
removes, iterations. :-)
Feedback on the impls would be handy. :-)
Cheers
