garbage collection - What is a GCRecord in a database? -
i have been introduced mvc, in uses sql database.
in of tables within project, there column optimisticlockfield, , gcrecord (both of type int).
i have found quite extensive info on optimistic/pessimistic locks. however, can't find gcrecord used for, or when used, nor why included.
the 'definition' 1 liner:
a gc record represents single garbage collection activity. independent of whether gc occured due manual gc request or allocation failure.
but still none wiser means, or if right 'definition' context.
is sql thing? or should used in most/all databases?
the gcrecord field used mark objects have been removed collection. part of mechanism called deferred deletion
database garbage-collection ssms
