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.

- 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.
- Metrics
  Teracloud® Streams provides metrics to help evaluate the health of Teracloud Streams services, to aid in diagnosing performance issues, and to analyze throughput of requests. You can use the streamtool checkinstancemetrics, streamtool checkdomainmetrics, streamtool getdomainmetrics, and streamtool checkresourcemetrics commands to view the metrics data.
- 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.
- SPL Compiler
  The SPL compiler is an incremental compiler that generates artifacts needed to run your stream application. These artifacts include, for example, C++ code for several entities in your SPL program and an application bundle file.
- 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.

Working with enrichment data from databases

Configure your Lookup Manager to use data from database: Most telecommunication projects store history and master data in a database, but the required business logic uses a subset of the data only.

Initializing Lookup Manager data from database: When you use at least one ITE application together with the Lookup Manager, which provides enrichment data, you must first initialize the Lookup Manager.

Updating Lookup Manager data from database: When you use at least one ITE application together with the Lookup Manager, which provides enrichment data, you need to update the enrichment data to track changes in there.

Deleting Lookup Manager data from database: When you use at least one ITE application together with the Lookup Manager, which provides enrichment data, the data can become irrelevant and you need to delete entries from the Lookup Manager.
