Abstract: Embodiments of the present disclosure are directed to a method for storing and processing data. The method includes identifying a database in a memory of a host device having one or more rows and one or more columns. A partition having a partition size is identified, and the one or more rows of the database is identified based on the partition size. The data stored in the one or more rows is converted into a column-based format, and the data is stored in a computational storage device in the column-based format. The computational storage device is configured to retrieve the data stored in the column-based format, in response to a query, and process the query based on the data.

Abstract: A method of shuffling data may include shuffling a first batch of data using a first memory on a first level of a memory hierarchy to generate a first batch of shuffled data, shuffling a second batch of data using the first memory to generate a second batch of shuffled data, and storing the first batch of shuffled data and the second batch of shuffled data in a second memory on a second level of the memory hierarchy. The method may further include merging the first batch of shuffled data and the second batch of shuffled data. A data shuffling device may include a buffer memory configured to stream one or more records to a partitioning circuit and transfer, by random access, one or more records to a grouping circuit.
