Sergei Petrunia c9042db619 Range Locking: add support for escalation barriers (#9290) ... Summary: Range Locking supports Lock Escalation. Lock Escalation is invoked when lock memory is nearly exhausted and it reduced the amount of memory used by joining adjacent locks. Bridging the gap between certain locks has adverse effects. For example, in MyRocks it is not a good idea to bridge the gap between locks in different indexes, as that get the lock to cover large portions of indexes, or even entire indexes. Resolve this by introducing Escalation Barrier. The escalation process will call the user-provided barrier callback function: bool(const Endpoint& a, const Endpoint& b) If the function returns true, there's a barrier between a and b and Lock Escalation will not try to bridge the gap between a and b.
