 Description   

Guidelines:

Should include

  • When and why can orphans be created? E.g. on a recipient during cloning, on a donor after a migration
  • How do we prevent data from being ripped out from active queries on a donor primary?
  • How do we prevent data from being ripped out from active queries on donor secondaries?

Code references

  • Where are the ranges-to-be-deleted stored in memory and on disk?
