Re: [eclipselink-users] Lifetime of Transient lists in the cache

[Tom Ware <tom.ware@xxxxxxxxxx>]

Hi Bernard,

  Have you looked at our Query Results cache.  It allows you to configure a 
cache for a query that will allow you to configure when it hits the database and 
when it returns the cached results?

  Here is a link to the javadoc in our QueryHints.  The next few hints listed 
in this javadoc related to the query results cache.
