set_number_partitions()

Sets the number of partitions (slices) of a space dimension on a hypertable. The new partitioning only affects new chunks.

Required arguments

Name	Type	Description
`hypertable`	REGCLASS	Hypertable to update the number of partitions for.
`number_partitions`	INTEGER	The new number of partitions for the dimension. Must be greater than 0 and less than 32,768.

Name	Type	Description
`dimension_name`	REGCLASS	The name of the space dimension to set the number of partitions for.

The dimension_name needs to be explicitly specified only if the hypertable has more than one space dimension. An error is thrown otherwise.

For a table with a single space dimension:


SELECT set_number_partitions('conditions', 2);

For a table with more than one space dimension:


SELECT set_number_partitions('conditions', 2, 'device_id');
