/*
It exercises code for asynchronous data flushing with regard to cache life time and its preload.
"flush + reload" means to tell the database to store all pending data then wipe the cached content and reload it from the db
"reload" only means to simulate situation when there is a pending flush for an origin but a new cache is about to preload
which is a corner case happening rarely ; this helps check the next preload operation will load correct data from the database anyway
Case 1: set | flush + reload | remove | set | remove | flush + reload | get ?= null
checks coalescing optimization for single key changes does work correctly for repeated removals of a key
Case 2: set | set | clear | flush + reload | count ?= 0
checks whether clear operation superseeds setting keys, the database must be empty for the origin
Case 3: set | set | clear | reload | count ?= 0
check the corner case when a data clear flush is pending but a new cache is about to preload
