Database system with replication based storage and redundancy coding based storage

A computer readable memory system comprises:

• a first memory that stores operational instructions that, when executed by a set of data in computing devices of the plurality of data in computing devices of a database system, causes the set of data in computing devices to:
• receive data of a data set;
• and
• temporarily store the data of the data set in accordance with a fault tolerance level;
• encode, via redundancy encoding scheme as indicated by the fault tolerance level, the data of data set to produce a plurality of encoded data segments, wherein the encoding of the data of the data set into encoded data segments of the plurality of data segments lags behind the temporarily storing the data of data set;
• a second memory that stores operational instructions that, when executed by a set of data S&P computing devices of the plurality of data S&P computing devices of the database system, causes the set of data S&P computing devices to:
• store the plurality of encoded data segments;
• a third memory that stores operational instructions that, when executed by a set of Q&R computing devices of the plurality of Q&R computing devices of the database system, causes the set of data Q&R computing devices to:
• receive a query request regarding the data set when the encoding of the data of the data set into encoded data segments is not complete due to the encoding lagging behind the temporarily storing of the data of data set;
• and
• the second memory further stores operational instructions that, when executed by the set of data S&P computing devices, causes the set of data S&P computing devices to:
• receive a set of query operations regarding the query;
• identify first data of the data of the data set that has been encoded into first encoded data segments;
• identify second data of the data of the data set that has not yet been the encoded into encoded data segments;
• retrieve the second data from the set of data in computing devices;
• and
• execute the set of query operations on the first and second data to produce at least a portion of a final result.
