implementing, by a system comprising a processor, an exclusive lock in a lock domain that identifies a data structure representative of a system B-tree (SBT) of an SBT system;
updating, by the system, an SBT generation number associated with the SBT, resulting in a first version of the SBT generation number;
executing, by the system, in response to execution of a lock loss call back at the SBT, a comparison of the first version of the SBT generation number with a second version of the SBT generation number to determine a change of version of the SBT generation number; and
identifying, by the system, a work assignment associated with the change of version of the SBT generation number.
