Subject [jira] Commented: (JCR-2619) improved internal representation of DATE values
Date Mon, 26 Apr 2010 20:04:32 GMT

    [ https://issues.apache.org/jira/browse/JCR-2619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12861073#action_12861073
] 

Tobias Bocanegra commented on JCR-2619:
---------------------------------------

the memory footprint of a 25 char long string is about 88bytes (56% less) - if you really
want to save space, why not use a byte array of the size 10 (for time and timezone) ?

> DATE values are currently internally represented as java.util.Calendar objects.
> Calendar objects have a huge memory footprint (approx 200bytes per instance) 
> and are mutable.
> i suggest to replace the internal DATE representation with a ISO8601 format string
> (immutable and approx. 85-90% smaller footprint).
