LIST DESCRIPTORS

Syntax
{ LIST | SHOW } DESCRIPTORS [IN DESCRIPTOR_SOURCE descriptor_source_name];
Description
​Descriptor​s are used for supporting Protocol Buffers, and creating a Descriptor Source allows users to associate ProtoBuf descriptors with specific Topics for data serialization and deserialization. This command provides a list of Descriptors that the user has access to. Descriptors are created when descriptor sources are created with CREATE DESCRIPTOR_SOURCE.
This command provides a list of Descriptor​s optionally filtered by a specific Descriptor Source.
Descriptors will only be listed if the current role has USAGE privileges on the descriptor source.
Arguments
descriptor_source_name
Optionally, this lists the Descriptors belonging to the specified Descriptor Source.
Examples
List all Descriptors
demodb.public/demostore# LIST DESCRIPTORS;
           Name           
--------------------------
  pageviews.PageviewsKey  
  pageviews.Pageviews     
List all Descriptors from Descriptor Source
From a list of all available Descriptors, we can pick one of the Descriptor Source names, e.g. pageviews:
demodb.public/demostore# LIST DESCRIPTORS;
           Name           
--------------------------
  pageviews.PageviewsKey  
  pageviews.Pageviews     
  employee.StaffKey       
  employee.Manager        
  employee.Employee       
  employee.Address
This name can be used to list only the Descriptors that were uploaded from the pageviews Descriptor Source:
demodb.public/demostore# LIST DESCRIPTORS IN DESCRIPTOR_SOURCE pageviews;
           Name           
--------------------------
  pageviews.PageviewsKey  
  pageviews.Pageviews
