Description

The feed publishes entities and observables in the selected content type to the specified destination location on an FTP server. Each time the outgoing feed task runs, it generates a data package containing zero or more entities, depending on the outgoing feed update strategy, and on the feed data source containing data that match the feed configuration.

Configure the outgoing feed#

  1. Create or edit an outgoing feed.

  2. From the Transport type drop-down menu, select SFTP upload.

  3. From the Content type drop-down menu, select the appropriate content type for the data you want to publish through the outgoing feed.
    The selected content type for the feed should match the actual format of the source data you are publishing through the feed.
    This can vary, depending on the dataset sources you retrieve the data for publication from.

  4. From the Datasets drop-down menu, select one or more existing datasets to use as sources to populate the outgoing feed content.
    For the feed not to be empty, at least one selected dataset should contain entities and observables in the same format as the configured content type for the feed.

  5. From the Update strategy drop-down menu, select the preferred method to populate the outgoing feed with data before publishing it.
    Update strategies help define how content is aggregated and packaged for publication when an outgoing feed task runs:

    • Append: every time the outgoing feed task runs, it fetches only new, unpublished data to generate the content for publication.
      The published packages contain only new entities and observables ingested in the platform after the previous execution of the outgoing feed.

    • Replace: every time the outgoing feed task runs, it fetches new and existing data to generate the content for publication.
      The published packages contain new and existing entities and observables included also in the previous execution of the outgoing feed.

    • Diff : this option is available only for the EclecticIQ Entities CSV and EclecticIQ Observables CSV content types. Every time the outgoing feed task runs, new data is compared against existing data to identify any differences between the two datasets:

      • At entity level: any entities added to or removed from the set, if EclecticIQ Entities CSV is the designated content type for the feed.

      • At observable level: any observable added to or removed from the entities in the set, if EclecticIQ Observables CSV is the designated content type for the feed.

      Depending on the selected CSV content option, each row in the CSV output contains information about one entity being added or removed, or one observable being added or removed.
      An extra diff column is added to the output CSV to indicate if a row, and therefore either an entity or an observable, has been added to or removed from the set.
      This option enables identifying changes in a feed between two executions without downloading the whole feed every time.

      Note

      Update strategies help define how content is aggregated and packaged for publication when an outgoing feed task runs:

      Update strategies rely on the last_updated_at database field to identify entities whose timestamp value was updated since the previous execution of the outgoing feed.
      Entities with a more recent timestamp value compared to the previous execution of the outgoing feed are packaged and included in the published content of the outgoing feed.

      • Changes to the data section of an entity create a new version of the entity.
        They also add a new log entry to the entity history to record the changes.

      • Changes to the meta section of an entity do not create a new version of the entity.
        However, they do update the timestamp value of the last_update_at database field.

  6. In the SFTP server URL field, enter the target sftp:// location on the SFTP server to upload the outgoing feed content to, so as to make it available for retrieval.
    Format: sftp://${sftp_server}:${port}/${path_to_target_directory}.
    Example: sftp://sftp.server.com:22/source-data/for-the-feed.

  7. In the Username field, enter a valid user name to authenticate and be granted the necessary authorization to access the location of the outgoing feed content.

  8. In the Password field, enter a valid password to authenticate and be granted the necessary authorization to access the location of the outgoing feed content.

  9. Select the Include documents attached to entities checkbox to include in the outgoing feed content also any attachments to the published entities such as MS Word documents or PDF files.

  10. Select the Use SSH key checkbox to enable logging in through SSH to apply this security layer to the outgoing feed.

  11. In the SSH private key field, paste the private SSH key you want to use to access the target location where the SFTP upload outgoing feed should publish content to.
