Subject [jira] [Created] (JCS-147) Provide file size limitation for Block Disk Cache and Indexed Disk Cache
Date Sat, 04 Apr 2015 20:35:33 GMT
Wiktor N created JCS-147:
----------------------------

             Summary: Provide file size limitation for Block Disk Cache and Indexed Disk Cache
                 Key: JCS-147
                 URL: https://issues.apache.org/jira/browse/JCS-147
             Project: Commons JCS
          Issue Type: New Feature
          Components: Indexed Disk Cache
    Affects Versions: jcs-2.0-beta-1
            Reporter: Wiktor N


Attached please find a patch, that provides additional mode of operation to Block and Index
Disk Caches, i.e. that instead of limiting the key count, you limit the content size. It's
a proxy for limiting the file size, but it works quite good.

The patch has additional length, as I moved:
src/main/java/org/apache/commons/jcs/utils/struct/LRUMap.java
to:
src/main/java/org/apache/commons/jcs/utils/struct/AbstractLRUMap.java

and then - created LRUMap, that implements size-based policy.

Also, in a separate file I provided update for website docs.

I did some testing, also performance, and it looks like, it doesn't introduce noticeable difference.
