[infinispan-issues] [JBoss JIRA] (ISPN-6845) A JDBC-based CacheLoader/CacheWriter that breaks down keys and values into multiple table columns

[ https://issues.jboss.org/browse/ISPN-6845?page=com.atlassian.jira.plugin.... ] Krzysztof Sobolewski commented on ISPN-6845: -------------------------------------------- I have a prototype implementation of this, but it's a direct extension of the existing classes/interfaces and the result is not really merge-worthy. It does the followng things: * The configuration of key/data name/type is changed from a single String to a List<String> so that we can declare multiple columns for the key and the value * The configuration builder uses varargs so source compatibility (not binary compatibility) is preserved * The Key2StringMapper interface is extended so that it can return multiple values (Objects, not String) for the key * The Key2StringMapper is also applied to the values Overall, it works, but is a little awkward (*Key*2StringMapper applied to *values*? Key2*String*Mapper that generates Object[]? etc). The code is in https://github.com/ksobolew/infinispan/tree/ISPN-6845 if someone wishes to take a look. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
