Adding an indexer adapter

Indexer adapters save data that is ready to be indexed by the Dgidx program.

The final component in your pipeline is generally an indexer adapter. These components take all record, dimension hierarchy, and index configuration information from the pipeline and combine it in a format that is ready for the indexer (Agidx or Dgidx). An indexer adapter will generally be the final component in a baseline update pipeline. Attributes of the indexer adapter control where and how it writes its output, as well as where and how it reads its index configuration input.

To add an indexer adapter:

  1. In the Pipeline Diagram editor, click New.
  2. Choose Indexer Adapter. The Indexer Adapter editor appears.
  3. In the Name text box, type a unique name for the indexer adapter.
  4. In the General tab, do the following:
    1. In the URL text box, type the location to which the indexed records are written, relative to the Pipeline.epx file.
    2. In the Output Prefix text box, type the prefix that will be attached to the output files.
    3. (Optional) Check Filter Unknown Properties if you want the indexer adapter to remove source properties from your records.
      Note: After mapping, source properties still exist as part of the Endeca record. Enabling this option removes those source properties so records consist exclusively of Endeca properties and dimension values.
    4. (Optional) Check Custom Compression and slide the bar to the appropriate level.
  5. (Optional) In the Sources tab, choose a record source and one or more dimension sources.
  6. (Optional) If you are using an Agraph in your implementation, do the following:
    1. Select Enable Agraph Support.
    2. In Number of Agraph Partitions, specify the number of child Dgraphs that the Agraph coordinates.
      Note: If you want to change the partition property, open the Properties view and modify which properties are enabled for rollup and record spec. For more detailed information, see the Endeca Advanced Development Guide.
  7. (Optional) In the Comment tab, add a comment for the component.
  8. Click OK.
    Note: Typically, there is only one indexer adapter per pipeline.
