    摘要： Partitioning a set of data using a binary format to more evenly distribute data values across a set of data partitions. By using a system of matching binary indices in a “back to front” manner, data values stored in or associated with data partitions are more evenly balanced.

    摘要翻译： 使用二进制格式对一组数据进行分区，以便在一组数据分区中更均匀地分布数据值。 通过使用以“从前到前”的方式匹配二进制索引的系统，存储在数据分区中或与数据分区相关联的数据值更均匀地平衡。

    摘要： Embodiments are directed to building an index structure for a relational database (RDB) table and for querying the RDB table. An aspect includes obtaining JSON documents from a RDB table, identifying JSON objects in the JSON documents and assigning identifiers for them, and building an index structure according to values in the JSON objects such that the index structure includes at least one node that records values in a JSON object and includes the identifier of the specific JSON object. Querying the RDB table includes receiving a query request including an indicator which indicates that the query is to be performed on JSON objects, and searching the index structure based on query conditions in the query request so as to determine a target JSON object that meets the query conditions.

    摘要翻译： 实施例涉及为关系数据库（RDB）表建立索引结构以及查询RDB表。 一方面包括从RDB表中获取JSON文档，识别JSON文档中的JSON对象并为其分配标识符，以及根据JSON对象中的值构建索引结构，以使索引结构至少包含一个记录值的节点 一个JSON对象，并包含特定JSON对象的标识符。 查询RDB表包括接收查询请求，该查询请求包括指示要对JSON对象执行查询的指示符，以及根据查询请求中的查询条件搜索索引结构，以便确定满足查询的目标JSON对象 条件。
