摘要： A query of spatial data is received by a database comprising a columnar data store storing data in a column-oriented structure. Thereafter, a spatial data set is mapped to physical storage in the database using a space-filling curve. The spatial data set is then compacted and such compacted data can be used to retrieve data from the database that is responsive to the query. Related apparatus, systems, techniques and articles are also described.

摘要： A database query of point data among two or more axes of a database is received. The database stores point data in distinct integer vectors with a shared dictionary. Thereafter, the dictionary is scanned to determine boundaries for each axis specified by the query. In response, results characterizing data responsive to the query within the determined boundaries for each axis are returned. Related apparatus, systems, techniques and articles are also described.
摘要翻译： 接收到数据库的两个或多个轴之间的点数据的数据库查询。 数据库使用共享字典将点数据存储在不同的整数向量中。 此后，扫描字典以确定查询指定的每个轴的边界。 作为响应，返回表征响应于针对每个轴的确定的边界内的查询的数据的结果。 还描述了相关设备，系统，技术和物品。

摘要： A query is received and an initial data flow graph comprising a plurality of nodes is generated for executing the query. The initial data flow graph is optimized using a model optimizer that accesses at least one of a plurality of patterns to identify a matching pattern and executes at least one optimization rule associated with a matching pattern. Execution of the query is then initiated using the optimized data flow graph. Related apparatus, systems, techniques and articles are also described.

摘要： A query is received which causes an initial data flow graph that includes a plurality of nodes that are used to execute the query is generated. Thereafter, the initial data flow graph is optimized using a model optimizer that includes an optimizer framework and an application programming interface (API). The optimizer framework provides logic to restructure the initial data flow graph and a rules engine for executing one or more optimization rules. The API allows for registration of new optimization rules to be executed by the rules engine. Execution of the query is then initiated using the optimized data flow graph. Related apparatus, systems, techniques and articles are also described.

摘要： A query statement is received that requires at least one calculated attribute. Thereafter, a data flow graph is generated that includes a plurality of nodes for executing the query. At least one of the nodes corresponds to the at least one calculated attribute and has at least one level of child nodes. The data flow graph is generated by generating at least one filter for each of the nodes corresponding to the at least one calculated attribute and by pushing down the generated filters to a corresponding child node. Once the data flow graph is generated, execution of the query can be initiated using the generated data flow graph. Related apparatus, systems, techniques and articles are also described.
