      Index Pipelines

      Index pipelines transform incoming data into PipelineDocument objects for indexing by Fusion-managed Solr service. An index pipeline consists of a series of configurable index pipeline stages, each performing a different transformation on the data before passing the result to the next stage in the pipeline. The final stage is the Solr Indexer stage, which transforms the PipelineDocument into a Solr document and submits it to Solr for indexing in a specific Collection.

      Each configured datasource has an associated index pipeline and uses a connector to fetch data to parse and then input into the index pipeline.

      Alternatively, documents can be submitted directly to an index pipeline or profile with the REST API; see Importing Data with the REST API.

      A pipeline can be reused across multiple collections. Fusion provides a set of built-in pipelines. You can use the Index Workbench or the REST API to develop custom index pipelines to suit any datasource or application.

      index pipeline

      When a Fusion collection is created using the Fusion UI, a pair of index and query pipelines are created to that pipeline, where the pipeline name is the collection name with the suffix "-default". This pipeline consists of a Field Mapping index stage.

      Although default pipelines are created when a Fusion collection is created, they are not deleted when the collection is deleted. This is because pipelines can be used across collections, so a named pipeline, although originally associated with a collection, can be used by several collections.
