While most persistence solutions choose to cache data rows and rebuild objects when a cache hit occurs, EclipseLink has gone further and caches entities with all the defined data conversions applied. This approach to caching greatly improves performance and reduces the amount of garbage created when accessing cached objects. The caching is also very flexible, allowing developers complete control over L1 and L2 cache usage, lifecycle, refreshing, cluster coordination and concurrency protection to minimize and handle stale data scenarios. As with all caching solutions the performance and scalability benefits are gained when the solution is tuned with respect to the applications usage of the data and the behavior of the underlying database, which is often shared with other applications in the enterprise.</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/2E151820-5D23-476F-B7FB-87ECFC416B54/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
