12.6. Configuring a Red Hat JBoss Data Virtualization VDB Sequencer

Include the relevant libraries

Choose one of the following for sequencing configuration

• Define sequencing configuration based on standard example provided in SOA-ROOT/eds/modeshape/resources/modeshape-config-standard.xml:

  <mode:sequencer jcr:name="Teiid VDB Sequencer" mode:classname="org.modeshape.sequencer.teiid.VdbSequencer">
    <mode:description>
      Sequences Teiid Virtual Databases (e.g., *.vdb) loaded under '/files', extracting the VDB metadata and the structure defined in the VDB's relational models.
    </mode:description>
    <mode:pathExpression>
      eds-store:default:/files(//)(*.vdb[*])/jcr:content[@jcr:data] => eds-store:default:/sequenced/teiid/vdbs$1
    </mode:pathExpression>
  </mode:sequencer>

• Configure via org.modeshape.jcr.JcrConfiguration:

  JcrConfiguration config = ...
  
  config.sequencer("Teiid VDB Sequencer")
        .usingClass("org.modeshape.sequencer.teiid.VdbSequencer")
        .loadedFromClasspath()
        .setDescription("Sequences Teiid Virtual Databases (e.g., *.vdb) loaded under '/files', extracting the VDB metadata and the structure defined in the VDB's relational models.")
        .sequencingFrom("/files(//)(*.vdb[*])/jcr:content[@jcr:data]")
        .andOutputtingTo("/sequenced/teiid/vdbs$1");
