Request¶
Route
POST /v1/commands/
Body
Note - An argument for this command requires a Python User-Defined Function (UDF). This function must be especially prepared (wrapped/serialized) in order for it to run in the engine. If this argument is needed for your call (i.e. it may be optional), then this particular command usage is NOT practically available as a REST API. Today, the trustedanalytics Python client does the special function preparation and calls this API.

Description
Assigns data to column based on evaluating a function for each row.
Notes¶
- The row UDF (‘func’) must return a value in the same format as specified by the schema. See Python User Functions.
- Unicode in column names is not supported and will likely cause the drop_frames() method (and others) to fail!
