Consolidation Transformation Strategies View

Simple Strategy

A simple strategy analyzes all the values of a port in a record group and selects one value. You specify a simple strategy for each port. The Consolidation transformation uses the port values selected by all simple strategies to create a consolidated record. Examples of simple strategies include the most frequent value in a port, the longest value in a port, or the most frequent non-blank value in a port.

Row-Based Strategy

A row-based strategy analyzes rows in the record group and selects one row. The Consolidation transformation uses the port values from that row to create a consolidated record. Examples of row-based strategies include the highest character count, the lowest number of blank fields, or the highest count of the most frequent fields.

Advanced Strategy

An advanced strategy analyzes a record group using strategies that you define. You build advanced strategies by using consolidation functions in an expression. The Consolidation transformation creates a consolidated record based on the output of the expression. The expression that you create can also use all of the functions available in the Decision transformation.

Consolidation Transformation Advanced Properties

Sort

Determines whether the transformation sorts the input rows on the Group By port data. The property is enabled by default.

Select the property if the input rows are not presorted.

Case Sensitive Sort

Determines whether the sort operation is case-sensitive. The property is enabled by default.

Output Mode

Determines whether the transformation writes all records as output or writes the consolidated records as output. The default value is All.

Cache File Directory

Specifies the directory to which the Data Integration Service writes temporary data for the current transformation. The Data Integration Service writes temporary files to the directory when the volume of input data is greater than the available system memory. The Data Integration Service deletes the temporary files after the mapping runs.

You can enter a directory path on the property, or you can use a parameter to identify the directory. Specify a local path on the Data Integration Service machine. The Data Integration Service must be able to write to the directory. The default value is the CacheDir system parameter.

Cache File Size

Determines the amount of system memory that the Data Integration Service uses to sort the input data on the transformation. The default value is 400,000 bytes. You can use a parameter to specify the cache file size.

Before it sorts the data, the Data Integration Service allocates the amount of memory that you specify. If the sort operation generates a greater amount of data, the Data Integration Service writes the excess data to the cache file directory. If the sort operation requires more memory than the system memory and the file storage can provide, the mapping fails.

Note: If you enter a value of 65536 or higher, the transformation reads the value in bytes. If you enter a lower value, the transformation reads the value in megabytes.

Tracing Level

Amount of detail that appears in the log for this transformation. You can choose terse, normal, verbose initialization, or verbose data. Default is normal.
