Create distributed hypertables
If you have a multi-node environment, you can create a distributed hypertable across your data nodes. First create a standard PostgreSQL table, and then convert it into a distributed hypertable.
You need to set up your multi-node cluster before creating a distributed hypertable. To set up multi-node, see the multi-node section.
- On the access node of your multi-node cluster, create a standard
PostgreSQL table:CREATE TABLE conditions (time TIMESTAMPTZ NOT NULL,location TEXT NOT NULL,temperature DOUBLE PRECISION NULL,humidity DOUBLE PRECISION NULL);
- Convert the table to a distributed hypertable. Specify the name of the table
you want to convert, the column that holds its time values, and a
space-partitioning parameter. For more information about space partitions,
see the space-partitioning section.SELECT create_distributed_hypertable('conditions', 'time', 'location');
