With a KV engine, if I want to list all keys in the directory /foo/, it only returns keys directly under /foo/
For example, if I have the following keys:
/foo/some_key
/foo/bar/some_other_key
A LIST operation on /foo/ returns some_key and bar/, while I would like to have some_key and bar/some_other_key
Describe the solution you'd like
Add a parameter to either recursively return ALL keys in the provided path.
Describe alternatives you've considered
Another way to do it would be to add a parameter specifying the depth up to which look recursively for keys.
