avantgardnerio opened a new issue, #508:
URL: https://github.com/apache/arrow-ballista/issues/508

   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   
   In my understanding, at present:
   
   1. Ballista allows git-refs to DataFusion and arrow
   2. This allows features to be rapidly added to DataFusion, then Ballista 
features to be based on them (i.e. ListingSchemaProvider)
   3. Except when a new DataFusion point release happens (i.e. v10)
   4. In this case, merging of git-ref PRs is put on hold while a release of 
Ballista is prepared
   5. After the Ballista release is live, then git-ref PRs can get merged 
again, and the cycle continues
   
   The problem with this is that from step 3-5, there's a "mutex" on master and 
PRs are blocked, essentially "feature freeze".
   
   **Describe the solution you'd like**
   
   Rather than blocking multiple PRs from many contributors, it might be 
preferable to always leave Ballista master pointed at git-refs of DataFusion, 
and instead when an RC is declared to make a release branch on which the only 
work done is switching from git-ref back to release version of DataFusion and 
any accompanying compile fixes etc.
   
   **Describe alternatives you've considered**
   
   Keep doing what we're doing now.
