摘要： A recipient node of a multi-node data partitioning landscape can receive, directly from a requesting machine without being handled by a master node, a first data request related to a table. A target node of a plurality of processing nodes can be identified to handle the data request. The determining can include the recipient node applying partitioning information to determine a target data partition of the plurality of data partitions to which the data request should be directed and mapping information associating each data partition of the plurality of data partitions with an assigned node of the plurality of processing nodes. The recipient node can redirect the data request to the target node so that the target node can act on the target data partition in response to the data request.

摘要： A dynamic split node defined within a calculation model can receive data being operated on by a calculation plan generated based on the calculation model. A partition specification can be applied to one or more reference columns in a table containing at least some of the received data. The applying can cause the table to be split such that a plurality of records in the table are partitioned according to the partition specification. A separate processing path can be set for each partition, and execution of the calculation plan can continue using the separate processing paths, each of which can be assigned to a processing node of a plurality of available processing nodes.

摘要： Based on one or more first columns of a table partitioned at a first level over multiple first level partitions, a first partition criteria is evaluated for a data record. Each of the at least first level partitions is further partitioned into a same number of second-level partitions using a same second partitioning method for all first level partitions. One first level partition is identified for storage of the data record, for example by determining the one of the at least two data server processes using the first partition criteria and a first partitioning method that differs from the second partitioning method. Based on one or more second columns of the table, a second partition criteria is evaluated for the data record, and the data record is stored in one of the second-level partitions of the at least two first level partitions.

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.
