Toolkits
A toolkit is a set of SPL artifacts, which are organized into a package. Toolkits make SPL or native functions and primitive or composite operators reusable across different applications.

Welcome
Learn about the core capabilities of Teracloud® Streams, its architecture, and key concepts.
Installing
Use this information to install, upgrade, and uninstall the Teracloud® Streams product.
Configuring
Create a basic or an enterprise domain which is a single point for configuring and managing common resources, security, and instances.
Administering
Administer the product by using the Teracloud® Streams graphical user interface, APIs, or the streamtool command-line interface.
Developing
Develop stream applications with the Streams Processing Language (SPL), Java, and Python.
Troubleshooting

- APIs
  Application programming interfaces (APIs) provide functions that simplify applications development.
- Job configuration overlays
  You can specify or change configuration parameters when you use the submitjob or updateoperators operations. The settings control submission constraints, host constraints and locations, and operator status. Parameters are captured and updated in the configuration JSON file. When you change the values in the job configuration overlay file, the changes override any previously set values.
- Commands
  Teracloud® Streams provides a number of commands you use to perform tasks.
- Operator model
  An operator model is an XML document that describes the basic properties of a primitive operator.
- Streams Processing Language (SPL)
  Streams Processing Language (SPL) is a distributed data flow composition language that is used in Teracloud® Streams. SPL has primitive types, program structures, and definitions that are tailored for streaming data.
- Toolkits
  A toolkit is a set of SPL artifacts, which are organized into a package. Toolkits make SPL or native functions and primitive or composite operators reusable across different applications.
  - Specialized toolkit requirements and restrictions
    Several of the specialized toolkits require RPMs that are not required by the Teracloud® Streams product. There are also toolkit restrictions on some platforms.
  - Toolkits
- SPLDOC markup
  You can use SPLDOC markup in the descriptions associated with the SPL artifacts in a toolkit. The spl-make-doc command generates HTML documentation from the marked up artifacts.

Operators

FlightPathEncounter: This operator tracks flying objects and calculates possible encounters between the objects in the future.
Geofence: The Geofence operator is used to manage user-defined geographical regions called geofences and provide information as entities move in and out of of these regions.
GeometryMapMatcher: The GeometryMapMatcher operator calculates edges of a road network that are within reach of a given area of interest (AOI).
Hangout: The Hangout operator is used to detect a basic pattern about a moving entity's location called a hangout.
MapStore: The MapStore operator stores geometry data for the edge network in a shared map store, which the PointMapMatcher operator can access.
OSMCorrelator: The OSMCorrelator correlates information read by the OSMXMLGeometrySource to map generated edge IDs back to the original Way ID from the OpenStreetMaps map (.osm file).
OSMPointMatcher: The OSMPointMapMatcher composite analyzes time based object location data to heuristically project points on a network of roads specified by an OpenStreetMaps XML map file.
OSMXMLGeometrySource: OSMXMLGeometrySource reads in an OSM XML map file (.osm file) and generates geometry tuples for consumption by the PointMapMatcher and PathMapMatcher operators.
PointMapMatcher: The PointMapMatcher operator analyzes time based object location data to heuristically project points on a network of edges, as the original data may be imprecise.
RegionMatch: The RegionMatch operator stores geographical regions (also called Geofences) together with a set of attributes per region.
SpatialGridIndex: The SpatialGridIndex operator stores objects and their location.
SpatialRouter: The SpatialRouter operator is used to split an input stream that contains geographical data into two or more output streams, based on the geographic location specified by each tuple.
