You can use ArcGIS Velocity to create analytic pipelines that perform real-time or big data analytics on event data. The Velocity app provides options for creating, configuring, saving, and viewing analytics.
Create an analytic
In the Velocity app, the menu on the left contains an Analytics section with options for creating real-time and big data analyses. Use these options to open the Real-Time Analytics or Big Data Analytics pages, where you can create analytics by clicking Create Analytic.
When creating a real-time analytic, choose an existing feed or create a feed. When creating a big data analytic, define a data source for the big data analytic.
Once you choose or create the feed or data source, begin configuring the analytic in the analytic editor. Use the analytic editor to configure tools, outputs, and additional data sources. Analytics can be saved, started, or further edited. Big data analytics can also be scheduled to run on a recurring basis.
Save an analytic
To save an analytic configuration, click Create Analytic and provide a name and, optionally, a description.
After creating the analytic, you can continue to configure additional feeds, sources, tools, and outputs. As changes are made, you can save the analytic by clicking Save in the upper right of the app. Analytics must have at least one input and one output before it can be started.
Analytic options
Once an analytic is created and saved, additional options and controls are available. To connect nodes, such as a data source to a tool, a tool to another tool, or a tool to an output, drag the output port of a node to connect it to the input port of another node.
The Smart Layout option in the analytic allows you to automatically apply horizontal or vertical arrangements as an analysis process is built. Additionally, the animated lines that appear when an analytic is actively running can be turned on or off using the Route Animation toggle button.
The Node Note option in real-time and big data analytic models allows you to add relevant information about a particular node including text, bulleted lists, hyperlinks, and code. To add a note to a node, select the node to activate the Note option, add your information, and click Apply to save the new note. A note icon displays on nodes with a note. Adding notes to nodes is a useful way to provide important information about nodes and analytic workflows in your organization.
Analytic pipelines
An analytic can have multiple feeds, data sources, tools, and outputs. These elements can be configured in an analytic as a single pipeline or multiple pipelines. A pipeline defines the flow of event data from a feed or data source to any number of tools and to any number of outputs.
Single-pipeline analytic
A single-pipeline analytic has a single processing path. This path can have one feed and one output or can have many tools in the pipeline, including tools that use additional data sources and one or more outputs.
Multiple-pipeline analytic
A multiple-pipeline analytic has more than one processing path for the event data.
