A data source loads static or near real-time data into a real-time or big data analytic. In real-time analytics, data sources load data used in conjunction with tools that require an ancillary spatial or tabular dataset to enrich, filter, join to, or calculate distance from events. In big data analytics, data sources load the data that will be processed by tools and written to outputs.
The following data source types are available in ArcGIS Velocity:
- Web and Messaging
The following are examples of using a data source:
- An environmental scientist configures an Amazon S3 source in a big data analytic to load hundreds of delimited .csv files for analysis.
- A GIS analyst configures a Feature Layer source in a real-time analytic to load United States Census Bureau census tract data to enrich incoming sensor observations with information about the census tract they intersect.
Add a source
You can add sources to existing real-time or big data analytics. Additionally, you can add a source when creating a new big data analytic. Follow the steps below to add a source when creating a new big data analytic:
- Open the ArcGIS Velocity app.
- Go to the Big Data Analytics page.
- Click Create Analytic.
- Click All sources and choose a source type:
- Web and Messaging
- Provide source configuration details. The configuration parameters vary depending on the source type.
- Configure the schema, key fields, and polling settings in the same way for all source types. For more information, see Configure input data.
The configured source is available in the big data analytic.
You can now add and configure tools to analyze the data and send the results of the analysis to various outputs.
Edit a source
You can edit an existing source in a real-time or big data analytic to adjust connection parameters, schema configuration, key fields, and polling settings. To edit a source in an analytic, do one of the following:
- In workflow view, expand the Source pane. In model view, double-click the source node to see additional details.
- Click the edit button to access the source configuration wizard.
