Command Server work and data files

Depending on the conditions of the transformation, such as input data file size and processing complexity, work and data files can significantly affect performance.

Work and data files are the two major sources of information used in the transformation phase of map execution. Data files are the input data specified at execution time. Work files created during validation contain data about the input and output data sources.

The data types defined by the transformation's type tree depend on the internal format of the data files and are ultimately determined by the business process. This internal format drives the validation phase. The storage characteristics of the data files also depend on the business process as well as the underlying operating system.

HCL Integration Platform offers a significant number of options for creating and using work files. Depending on the conditions of the transformation, such as input data file size and processing complexity, some of these options can significantly affect performance. Reusing Work Files, Paging and WorkSpace in Memory present the performance impact of these options.

The size requirements for work files ultimately depend on the number of type instances found in the input data file and generated in the output data file. The number of type instances found in both cases depends greatly on the type definitions. To save work file space, type instances are only recorded in the workspace if needed later in the transformation process.
