Hierarchical data limitations

Hierarchical data limitations

When you use the Hierarchy Parser transformation, be aware of the following limitations.

Source file size

The Hierarchy Parser transformation can process source files that are up to 1.5 GB in size. To process files that are larger than 1.5 GB, use an intelligent structure model. For more information about intelligent structure models, see
Components
.

Handling of Boolean data types

The Hierarchy Parser transformation always returns 0 for Boolean data type input.

Hierarchical schema that is based on an XSD file

When you associate a hierarchical schema that is based on an XSD file with a Hierarchy Parser transformation, note the following limitations.
  • The Hierarchy Parser transformation does not support the following XSD component types:
    • xsd:any
    • xsd:type
    • mixed
    • xsi:type
    • default values
    • fixed values
    • no type, for example
      <xs:element name="A" maxOccurs="unbounded"/>
  • The Hierarchy Parser transformation provides limited support for large or complex XSD files, such as files that contains more than 10,000 elements and attributes, recursive elements, or complex deep hierarchies. To use an XSD that contains such elements or hierarchies, use the Structure Parser transformation.
