Description

Currently, we can get checkpoint config from rest api[1], the response contains the information as below

• timeout
• min_pause
• max_concurrent
• externalization

But did not contain the type of CheckpointBackend, but in some scenarios, we want to get the CheckpointBackend type from Rest, this issue wants to add the simple name of the CheckpointBackend in the checkpoints/config rest with key }}{{checkpoint_backend, so the response will contain the information such as below

• timeout
• min_pause
• max_concurrent
• checkpoint_backend 
• externalization
