Embodiment Construction

[0115] Various embodiments described herein generally relate to inter-device coordination to improve distributed indexing where parallel processing is used to access data of a dataset. The data of the data set can be divided into multiple super units, and the data in each super unit can be further divided into multiple data units. Within each data unit, data may be organized into a set of data records, each data record comprising the same set of data fields populated with data values. For each superunit, a set of indexes can be generated through which data within the superunit can be accessed more quickly, including a superunit index corresponding to the superunit as a whole and each corresponding to a data unit within the superunit One or more cell indices of one of . Within each unit index, data records within the corresponding data unit may be found present in the data value index within the selected subset of data fields. For each selected data field, the unique value in...

Abstract

An apparatus including a processor to receive search criteria including a data value for a search within a data field; in response to the receipt of the query instructions, and for each data cell within a super cell, perform the specified search by comparing the data value to ranges of values indicated in a corresponding cell index to determine whether the data cell includes a data record meetingthe search criteria, and in response to a determination that the data cell includes such a data record, use a unique values index in the cell index to search the data records of the data cell to identify one or more data records meeting the search criteria; and in response to identifying at least one data record meeting the search criteria, provide an indication that at least the data cell includes at least one data record meeting the search criteria.
