摘要： A method for estimating contents of a cache determines table descriptors referenced by a query, and scans each page header stored in the cache for the table descriptor. If the table descriptor matches any of the referenced table descriptors, a page count value corresponding to the matching referenced table descriptor is increased. Alternatively, a housekeeper thread periodically performs the scan and stores the page count values in a central lookup table accessible by threads during a query run. Alternatively, each thread independently maintains a hash table with page count entries corresponding to table descriptors for each table in the database system. A thread increases or decreases the page count value when copying or removing pages from the cache. A page count value for each referenced table descriptor is determined from a sum of the values in the hash tables. A master thread performs bookkeeping and prevents hash table overflows.
摘要翻译：用于估计高速缓存的内容的方法确定由查询引用的表描述符，并扫描存储在高速缓存中的表描述符的每个页头。如果表描述符匹配任何引用的表描述符，则增加与匹配引用表描述符相对应的页计数值。或者，管家线程周期性地执行扫描，并且在查询运行期间将页计数值存储在由线程访问的中央查找表中。或者，每个线程独立地维护具有对应于数据库系统中的每个表的表描述符的页计数条目的散列表。当从缓存中复制或删除页面时，线程会增加或减少页计数值。每个引用的表描述符的页计数值由哈希表中的值的总和确定。主线程执行簿记并防止哈希表溢出。

摘要： A database table is provided. The database table includes several column tuples. A column is selected in the database table. The column tuples of the selected column are partitioned into several bins. Each bin includes a range of tuples and associated metadata. The associated metadata includes at least one of: a minimum tuple value for the tuples in the bin, a maximum tuple value for the tuples in the bin, a minimum tuple identifier for the bin and a maximum tuple identifier for the bin. The bins are sorted based on the tuple values to provide an approximate index for the database.
