The Structure Parser transformation transforms your input data into a user-defined structured format based on an
intelligent structure model
. You can use the Structure Parser transformation to analyze data such as log files, clickstreams, XML or JSON files, Word tables, and other unstructured or semi-structured formats.
You can connect a Structure Parser transformation to the following types of sources:
A Source transformation based on a flat file to process local input files
A Source transformation based on a Hadoop Files V2 connection to stream input files in HDFS or to process local input files
When you configure a Structure Parser transformation, you associate it with an
intelligent structure model
. An
intelligent structure model
is an asset that
Intelligent Structure Discovery
generates to represent the data that you expect the model to parse at run time. You can create a model before you configure the Structure Parser transformation or as you configure it.
Intelligent Structure Discovery
generates the
intelligent structure model
based on a sample of your input data or a schema that you provide. You can create a model from the following input types:
Avro files
Cobol copybooks
Data within PDF form fields
Data within Microsoft Word tables
JSON files
Machine generated files such as
weblogs and clickstreams
Microsoft Excel files
ORC files
PDF files
Parquet files
Text files, including delimited files such as CSV files and complex files that contain textual hierarchies
XML files
XSD files
After
Intelligent Structure Discovery
generates the
intelligent structure model
, you can refine the model and customize the structure of the output data. You can edit the nodes in the model to combine, exclude, flatten, or collapse them.
