Abstract: Processing resources at a storage system for a database server are utilized to perform aspects of a join operation that would conventionally be performed by the database server. When requesting a range of data units from a storage system, the database server includes join metadata describing aspects of the join operation for which the data is being requested. The join metadata may be, for instance, a bloom filter. The storage system reads the requested data from disk as normal. However, prior to sending the requested data back to the storage system, the storage system analyzes the raw data based on the join metadata, removing a certain amount of data that is guaranteed to be irrelevant to the join operation. The storage system then returns filtered data to the database server. The database system thereby avoids the unnecessary transfer of certain data between the storage system and the database server.
Abstract translation: 利用用于数据库服务器的存储系统处理资源来执行通常由数据库服务器执行的连接操作的方面。 当从存储系统请求一系列数据单元时，数据库服务器包括描述正在请求数据的连接操作的方面的连接元数据。 连接元数据可以是例如布隆过滤器。 存储系统正常从磁盘读取所请求的数据。 然而，在将所请求的数据发送回存储系统之前，存储系统基于连接元数据分析原始数据，去除与加入操作无关的一定量的数据。 存储系统然后将过滤的数据返回到数据库服务器。 因此，数据库系统避免了存储系统和数据库服务器之间的某些数据的不必要的传送。
