Create a Step Using QuickStart

Before you begin

You need:

Java SE JDK 8
MarkLogic Server (See Version Compatibility.)
Chrome or Firefox for QuickStart

About this task

A flow must have at least one step. In QuickStart, steps can be created when editing the flow.

Procedure

Navigate to the flow definition of the flow you want.
1. In QuickStart's navigation bar, click Flows.
2. In the Manage Flows table, search for the row containing the flow.
  
  Tip: To make your search easier, you can sort the table by one of the columns.
3. Click the flow's name.
In the flow definition page, click New Step.
In the New Step dialog, choose the Step Type.
- Ingestion
- Mapping
- Matching
- Merging
- Mastering
- Custom
If you select Custom, also choose the Custom Step Type.

The Custom Step Type can be Ingestion, Mapping, Mastering, or Other. The custom step type provides a more specific step definition with default settings.

Configure the step settings.

Expand the Advanced Settings section for additional fields.
To add a custom hook, also expand the Custom Hook section.
See Creating a Custom Hook Module.

QuickStart Step - New Ingestion Step dialog


Field	Description
Name	The name of the step instance.
Description	(Optional) A description of the step.
Target Database	The database where to store the processed data. Choose the STAGING database where you want to store the ingested data. Default is `data-hub-STAGING`.
Additional Target Collections	Collection tags to add to the processed records. By default, the processed records are added to the collection with the same name as the step. You can add the records to additional collections by specifying one or more collection tags. Click to add more collection tags. Click next to a collection tag to delete it.
Batch Size	The number of documents to process per batch. A smaller batch size provides finer granularity in the jobs reporting. However, a smaller batch file also costs more because of the processing overhead. Must be 1 or more. Default is 100.
Thread Count	The number of threads to use when running a flow. Default is 4.
Custom Hook: Module	The path to your custom hook module.
Custom Hook: Parameters	Parameters, as key-value pairs, to pass to your custom hook module.
Custom Hook: User	The user account to use to run the module. Default is the user running the flow; e.g., `flow-operator`.
Custom Hook: RunBefore	For a pre-step hook, set to true. For a post-step hook, set to false.
