Storage of row data and parity data via different storage mechanisms

A database system includes:

• at least one processor;
• and
• a memory that stores operational instructions that, when executed by the at least one processor, cause the database system to:
• receive a plurality of records of a dataset for storage, wherein each of the plurality of records include a plurality of values corresponding to a plurality of fields of the dataset;
• generate a plurality of segment row data from the plurality of records, wherein each segment row data includes a corresponding one of a plurality of mutually exclusive proper subsets of the plurality of records;
• generate a plurality of parity data corresponding to the plurality of segment row data;
• store the plurality of segment row data via a first storage mechanism;
• facilitate storage of the plurality of parity data via a second storage mechanism;
• facilitate execution of a plurality of queries against the dataset by accessing the plurality of segment row data via the first storage mechanism;
• detect a storage failure of one of the plurality of segment row data via the first storage mechanism;
• and
• recover the one of the plurality of segment row data for storage via the first storage mechanism based on accessing at least one of the plurality of parity data via the second storage mechanism.

A non-transitory computer readable storage medium comprises:

• at least one memory section that stores operational instructions that, when executed by a processing module that includes a processor and a memory, causes the processing module to:
• receive a plurality of records of a dataset for storage, wherein each of the plurality of records include a plurality of values corresponding to a plurality of fields of the dataset;
• generate a plurality of segment row data from the plurality of records, wherein each segment row data includes a corresponding one of a plurality of mutually exclusive proper subsets of the plurality of records;
• generate a plurality of parity data corresponding to the plurality of segment row data;
• store the plurality of segment row data via a first storage mechanism;
• facilitate storage of the plurality of parity data via a second storage mechanism;
• facilitate execution of a plurality of queries against the dataset by accessing the plurality of segment row data via the first storage mechanism;
• detect a storage failure of one of the plurality of segment row data via the first storage mechanism;
• and
• recover the one of the plurality of segment row data for storage via the first storage mechanism based on accessing at least one of the plurality of parity data via the second storage mechanism.
