A method includes receiving, by a first computing entity of a database system, a data set that is organized in rows and columns. The method further includes determining whether to partition the data set based on a parameter associated with the data set. When determining to partition the data set, the method includes determining partitioning parameters for the data set, and partitioning the data set into a plurality of data partitions in accordance with the partitioning parameters. The method further includes determining a first coding scheme for a first data partition and determining a first number of first raw data segments for a first segment group of the first partition based on the coding scheme. The method further includes dividing the first partition to produce the first number of first raw data segments for storage in the database system.
