Partitioning allows the decomposition of large table data into smaller parts. Vertical partitioning is where the data is partitioned along column boundaries and data from a subset of columns of a table are grouped and stored together; horizontal partitioning is where the data is partitioned along row boundaries satisfying a given criteria and stored together.
