[dna-issues] [JBoss JIRA] Commented: (DNA-37) Federate schema information from relational sources

[ https://jira.jboss.org/jira/browse/DNA-37?page=com.atlassian.jira.plugin.... ] Randall Hauch commented on DNA-37: ---------------------------------- Updated three patch files created by BCar (who is currently having login issues) that restructure this connector. From Brian: - DNA-37_deletes_and_project_pom.patch - Deletes the existing dna-common-jdbc project and substantially all of the existing files in the dna-connector-metadata project. At the very bottom, it also makes changes to the master project pom, removing the reference to the dna-common-jdbc module and making all of the JDBC driver JARs be test-scoped so that we don't end up with a compile time dependency in all of our projects (we currently do, I checked). I also accidentally commented out the dna-sequencer-java module. That's unintentional, but it seems safer to let you not patch that one line than to try to redo the whole patch file. - DNA-37_graph_changes.patch - Adds a new read-only path-based repository framework. This is intended to complement the map repository framework, although it does not yet support writes. The patch also corrects a minor error that I caught in the name of one of the messages. - DNA-37_jdbc_meta_connector.patch - Adds the JDBC metadata connector itself along with its associated tests. The patch is surprisingly lengthy (due mostly to the large number of configurable properties on the source), but its conceptually very simple. The JdbcMetadataSource is patterned after the JpaSource, but it creates a PathRepositoryConnection instead of a MapRepositoryConnection. The JdbcPathRepository is persistent across connections (like the InfinispanRepository, JBossCacheRepository, InMemoryRepository, and InMemoryRepository, but unlike the SimpleJpaRepository), and provides an internal class that implements the PathWorkspace interface to do the bulk of the connector-specific work. This class has 1 method each for creating the 8 different node types (root node, catalog node, schema node, tables node, table node, column node, procedures node, procedure node). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
