Job rating chart and details - 7.3

This section provides visual representation of the investigated data related to the complexity rating of all Jobs in the audited project.

The chart represents quantitative and qualitative structures that show the number of Jobs used in the project along with their complexity rating, ranging from very simple to very complex.

Job complexity rating is calculated using numeric values specific to the elements complexity in the investigated Job. Examples of those elements are number of components used in the Job, number of context variables used in the Job, number of mapper components used in the Job and so on.

The list below gives the basic rating factors for calculating Job complexity:

• Components_rating = simpleComponents_rating + complexComponents_rating, where:
  • simpleComponents_rating = n * number of simple components used in the Job, where simple components refer to all the components other than those listed in the file <studio>/plugins/org.talend.commandline.audit_<version>/complexComponents.properties
  • complexComponents_rating = n * number of complex components used in the Job, where complex components refer to the components listed in the file <studio>/plugins/org.talend.commandline.audit_<version>/complexComponents.properties
• parameterCount_rating = n * number of context variables used in the Job * number of contexts
• Transformer_rating = mapCount_rating + mapColumnsCount_rating + mapInput_rating + mapOutput_rating, where:
  • mapCount_rating = n * number of the mapper components used in the Job, where mapper components refer to tMap and tXMLMap
  • mapColumnsCount_rating = n * number of columns of input and output schemas
  • mapInput_rating = n * number of input connections in the mapper components(s) used in the Job
  • mapOutput_rating = n * number of output connections in the mapper components(s) used in the Job
• customCodeComponents = number of components with Java code used in the Job, such as tJava.

where "n" is a coefficient that helps balancing the actual "weight" of each criteria in the audit results. For the coefficient values, check the file <studio>/plugins/org.talend.commandline.audit_<version>/rating.properties.

The formula for rating a Job is:

Job_Rating = Components_rating * 2 + parameterCount_rating + Transformer_rating + customCodeComponents

The resulting figures are defined as the following to give the different Job complexity ratings used:

• 0 - 50: very simple,
• 51 - 100: simple,
• 101 - 300: moderate,
• 301 - 500: complex,
• > 500: very complex.

The Job rating chart is accompanied (in the Job rating - details section in Talend Project Audit) by Job rating details providing numeric values for each complexity element shown.

The below table lists the numeric values for different complexity elements of the investigated Job.
