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.
- 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.

Connecting the connections.xml and the LookupMgrCustomizing.xml files

Some settings in the connections.xml file, which is required by the com.ibm.streams.db toolkit and its operators, must correlate with Lookup Manager parameters and with settings in the LookupMgrCustomizing.xml file.

Lookup Manager application – connecting the connections.xml and LookupMgrCustomizing.xml files

Procedure

Set the name attribute of the connection_specification element to the value of the lm.db.connectionName parameter. For example, SAMPLE as shown in the below figure.
Set the name attribute of the access_specification element to the value of the Name attribute of the DataSource element that is part of the LookupMgrCustomizing.xml file. For example, DimMaster1 as shown in the figure.
Set the column names for the native_schema element, so they fit to the database schema. Use the same names for the Name attributes of the ValueDefinition elements in the LookupMgrCustomizing.xml file.
Set the SPLType attributes of the ValueDefinition elements in the LookupMgrCustomizing.xml file according to the type mapping described in the com.ibm.streams.db toolkit.
