    • Efficient reclamation of available memory slots in a computer memory storage unit is achieved by identifying clusters of available memory spaces resulting from the deletion of a record from the storage unit. A cluster may include one or more contiguous available memory slots. An active cluster is elected by selecting the larger of two clusters, the first being the largest cluster resulting solely from processing of the current record delete request and the second being an active cluster identified in a prior record delete operation. Other clusters are defined as passive clusters. When a record is to be written into the disk memory, available memory slots in the active cluster are first used, following by unused memory slots and then by available memory slots in passive clusters.
    • 通过识别从存储单元删除记录而产生的可用存储器空间的集群来实现对计算机存储器存储单元中的可用存储器插槽的有效回收。 集群可以包括一个或多个连续可用的存储器时隙。 通过选择两个集群中较大的一个集群来选出一个主动集群,第一个集群是唯一由处理当前记录删除请求而产生的最大集群,第二个是在先前的记录删除操作中标识的活动集群。 其他集群被定义为被动集群。 当将记录写入磁盘存储器时,首先使用活动集群中的可用内存插槽,然后使用未使用的内存插槽,然后再使用被动集群中的可用内存插槽。
