Hi everybody!!
I have developed a cache component to support a web application with JBossCache and it works fine.
I have chosen a JDBCCacheLoader to deal with persistence activities. Now for a particular reason I have to schedule a task (during the night) that perform some activities on my contents tree.
To visit all my nodes I have set up a recursive function that perform this instruction "node.getChildren()" but it seems quite slow with lots of entries. I have placed an index on "FQN_parent" column to improve the performance and I have observed a great improvement (about 100 time).
Considering that JDBC retrieve metadata about index could it be a good idea to support this kind of activities?
