Abstract
Example apparatus and methods detect a query to a partition in a table store that is arranged in a table-entity-property organization. A partition is a collection of entities having the same partition key value. If the query seeks to filter on a specific entity in the partition, then the partition may be copied to a memory (e.g., structured shared cache, shared memory) that is prepared with one or more indexes that facilitate filtering the partition. Example apparatus and methods may copy the partition from the table store into the memory and then filter the partition on the specific field from the memory using the one or more indexes. Filtering the partition on the specific field may proceed in parallel, perhaps massively in parallel, using all the indexes available for the memory.
