In a mapping, you can configure a source transformation to represent a single Microsoft CDM Folders V2 object.
The following table describes the Microsoft CDM Folders V2 source properties that you can configure in a source transformation:
Property
Description
Connection
Name of the source connection.
Source Type
Type of the CDM folder source objects.
Select Single Object or Parameter.
Object
Name of the source object.
Select an existing object.
The following table describes the Microsoft CDM Folders V2 source advanced properties that you can configure in a Source transformation:
Property
Description
Concurrent Threads
Number of concurrent connections to read data from CDM Folders V2.
When you read from a large file or object, consider spawning multiple threads to process data.
Default is 10.
Block Size
Divides a large file or object into smaller parts each of specified block size.
When you read from a large file, consider dividing the file into smaller parts and configure concurrent connections to spawn the required number of threads to process data in parallel.
Default is 8 MB.
File System Name Override
Overrides the default file system name at run time with the file system name that you specify.
CDM Folder Override
Overrides the default CDM folders.
You can use the following paths for CDM folder override:
- /
- /folder1
- /folder1/folder2
- /folder1/filename, for example, /folder1/default.manifest.cdm.json or /folder1/model.json
Entity Name Override
Overrides the default entity name in the manifest.json or model.json file.
Tracing Level
Sets the amount of detail that appears in the log file. You can choose terse, normal, verbose initialization or verbose data.
Default is normal.
Note: You cannot use special characters in an entity name.
Overriding the source advanced properties
You can choose to override the default file system name, CDM folder, or entity name in the source advanced properties.
During mapping development you might use connection attributes, and during run time you can change the attributes without changing the connection attributes.
The CDM folder path and entity name must be valid when you override the default file system name, CDM folder, or entity name. Otherwise, the mapping fails with an error.
You can override the file system name when you select the file system name override option. For example, if you configured connection attributes for file system name cdmsd, CDM folder path demo/model, and the entity name ff_cdm, you can change the attributes during run time. You can select the file system name override and specify the system name cdmsd_prod. However, cdmsd_prod must have the same CDM folder path and the entity name that you specified in Microsoft CDM Folders V2 connection.
You can also override the filename when you select the CDM folder override option. For example, if you specified the CDM folder path /folder1/default.manifest.cdm.json in the Microsoft CDM Folders V2 connection to read from manifest.cdm.json file, you can choose to read from model.json file during run time.
