Add region cache

Open ekexium opened this issue 4 years ago • 0 comments

The previous UCP challenge #114 didn't finish the task. We'll use this issue to track the progress.

Todo

  • [x] The minimal region cache #291
  • [ ] Test
  • [ ] Save unnecessary PD requests if they are querying the same region
  • [ ] Finer grained error handling
