摘要： A database query optimization method is provided for database queries that include predicates, the queries being directed to at least one database table having data in rows and columns. The method includes associating a lineage bit set with each row of the database table, the lineage bit set providing a binary predicate state indication whether each predicate is met or are not met by data in the row. A dependency bit set is established to provide a binary indication of the predicates that are included in each query. Queries are applied against the database table by a logical operation between the lineage bit set and the dependency bit set. A database query optimization data structure includes a lineage bit set associated with each row in the database table. The lineage bit set provides a binary predicate state indication whether each predicate is met or are not met by data in the row. The data structure further includes a dependency bit set that provides a binary indication of the predicates included in each query.
摘要翻译：为包含谓词的数据库查询提供数据库查询优化方法，查询指向至少一个具有行和列数据的数据库表。该方法包括将谱系位集合与数据库表的每一行相关联，提供二进制谓词状态指示的谱系位集合是否满足或不满足该行中的数据的每个谓词。建立依赖位集合以提供包含在每个查询中的谓词的二进制指示。通过谱系位集和依赖位置位之间的逻辑运算，对数据库表应用查询。数据库查询优化数据结构包括与数据库表中的每一行相关联的谱系位集合。谱系位集提供二进制谓词状态指示，每个谓词是否满足或不满足行中的数据。数据结构还包括依赖性位集合，其提供包括在每个查询中的谓词的二进制指示。

摘要： A distributed data management system has multiple virtual machine nodes operating on multiple computers that are in communication with each other over a computer network. Each virtual machine node includes at least one data store or “bucket” for receiving data. A digital hash map data structure is stored in a computer readable medium of at least one of the multiple computers to configure the multiple virtual machine nodes and buckets to provide concurrent, non-blocking access to data in the buckets, the digital hash map data structure including a mapping between the virtual machine nodes and the buckets. The distributed data management system employing dynamic scalability in which one or more buckets from a virtual machine node reaching a memory capacity threshold are transferred to another virtual machine node that is below its memory capacity threshold.
