johnwagster opened a new pull request #5469: added deletion of state for Functions
URL: https://github.com/apache/pulsar/pull/5469
 
 
   ### Motivation
   
   Adding support for state deletion for Functions.  Ran into a use-case where it would be nice to be able to let go of state wherein the key is changing but the data itself is ephemeral. 
   
   ### Modifications
   
   I've reflected the changes in the bookkeepr API back through in the context and state context API's so that you can delete on a put by passing null or call the new api for delete.
   
   ### Verifying this change
   
   This change added tests and can be verified as follows:
    - Running the unit tests available in the ContextImplTest and ContextStateImplTest
   
   ### Does this pull request potentially affect one of the following parts:
   
     - The public API: yes; added deletion to Function context and state context APIs
   
   ### Documentation
   
     - Does this pull request introduce a new feature? - yes
     - If yes, how is the feature documented? - JavaDocs
