[jbosscache-issues] [JBoss JIRA] Commented: (JBCACHE-1501) Make JDBCCacheLoader easily subclassable

[Manik Surtani (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBCACHE-1501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12460202#action_12460202 ] 

Manik Surtani commented on JBCACHE-1501:
----------------------------------------

I have made the constructXYZSql() methods as well as the table construction DDL generation methods protected rather than private in the abstract AdjListJDBCCacheLoaderConfig class.  This way your impl can simply extend JDBCCacheLoaderConfig and override the SQL generation for inserts and updates to add a timestamp.

> We have a requisite to remove old data from datastore that has not been used for a long time, or for example, as a result of an scheduled task, for example, every midnight, or data that is in DB for longer than 6 hours.
> We are trying to subclass JDBCCacheLoader, to add a timestamp column, so we can remove old data from DB, but this class is not meant for subclassing, so we have to almost rewrite it completely, and also configs, and so on.
