Recommended: Use with Wrangler version 4.4.0 and above due to an important bug fix CDAP-17732.
The GENERATE-UUID directive generates a universally unique identifier (UUID) of the record.
Syntax
generate-uuid :column
The column
is set to the UUID generated for the record.
Usage Notes
The GENERATE-UUID directive generates a type 4, pseudo-randomly generated UUID. The UUID is generated using a cryptographically strong pseudo-random number generator.
Example
Using this record as an example, where you would like to generate a random identifier for the record to uniquely identify it:
{ "x": 1, "y": 2 }
Applying this directive:
generate-uuid :uuid
results in a record similar to this (the value of uuid
will vary):
{ "x": 1, "y": 2, "uuid": "57126d32-8c91-4c00-9697-8abda450e836" }
