The
IndexDeletionPolicy
is currently instantiated byIndexShard
and is then passed through to the engine as a parameter. That's a shame as it is really just an implementation detail and the engine already has a method to acquire a commit.This is preparing for a follow up PR that will we connect the index deletion policy with a new translog deletion policy.
