LINEAR KEY Partitioning Type

Syntax

LINEAR PARTITION BY KEY ([column_names])
[PARTITIONS (number_of_partitions)]

Description

LINEAR KEY partitioning is a form of partitioning, similar to KEY partitioning.

LINEAR KEY partitioning makes use of a powers-of-two algorithm, while KEY partitioning uses modulo arithmetic, to determine the partition number.

Adding, dropping, merging and splitting partitions is much faster than with the KEY partitioning type, however, data is less likely to be evenly distributed over the partitions.

Example

CREATE OR REPLACE TABLE t1 (v1 INT)
  PARTITION BY LINEAR KEY (v1)
  PARTITIONS 2;
