doctl databases pool create <database-cluster-id> <pool-name> [flags]
c
Creates a connection pool for the specified database cluster.
In addition to the pool’s name, you must also use flags to specify the pool’s target database, its size, and a database user that the pool uses to authenticate. If you do not specify a user, the field is set to inbound user. An example call would be:
The pool size is the minimum number of connections the pool can handle. The maximum pool size varies based on the size of the cluster.
There’s no perfect formula to determine how large your pool should be, but there are a few good guidelines to keep in mind:
We recommend starting with a pool size of about half your available connections and adjusting later based on performance. If you see slow query responses, check the CPU usage on the database’s Overview tab. We recommend decreasing your pool size if CPU usage is high, and increasing your pool size if it’s low.
You can get a list of existing connection pools by calling:
doctl databases pool list <database-cluster-id>
You can get a list of existing database clusters and their IDs by calling:
doctl databases listThe following example creates a connection pool named example-pool for a database cluster with the ID ca9f591d-f38h-5555-a0ef-1c02d1d1e35. The command uses the --size flag to set the pool size to 10 and sets the user to the database’s default user:
doctl databases pool create ca9f591d-f38h-5555-a0ef-1c02d1d1e35 example-pool --size 10
