Create a database
influxctl database create command
to create a database in your InfluxDB Cloud Dedicated cluster.
If you haven’t already, download and install the
influxctl database createcommand and provide the following:
- (Optional) Database retention period (default is infinite)
- Database name (see Database naming restrictions)
influxctl database create --retention-period 30d <DATABASE_NAME>
Retention periods cannot be updated
Retention periods cannot be changed after a database is created. To move to a different retention period, create a new database with the retention period you want and migrate existing data to the new database.
Retention period syntax
--retention-period flag to define a specific
for the database.
The retention period value is a time duration value made up of a numeric value
plus a duration unit. For example,
30d means 30 days.
A zero duration retention period is infinite and data will not expire.
The retention period value cannot be negative or contain whitespace.
Valid durations units include
- m: minute
- h: hour
- d: day
- w: week
- mo: month
- y: year
Example retention period values
3d: 3 days
6w: 6 weeks
1mo: 1 month (30 days)
1y: 1 year
30d30d: 60 days
2.5d: 60 hours
Database naming restrictions
Database names must adhere to the following naming restrictions:
- Must contain two or more characters
- Cannot start with an underscore (
- Cannot contain whitespace characters, double quotes (
"), or percent signs (
InfluxQL DBRP naming convention
In InfluxDB 1.x, data is stored in databases and retention policies. In InfluxDB Cloud Dedicated, databases and retention policies have been merged into databases, where databases have a retention period, but retention policies are no longer part of the data model. Because InfluxQL uses the 1.x data model, a database must be mapped to a v1 database and retention policy (DBRP) to be queryable with InfluxQL.
When naming a database that you want to query with InfluxQL, use the following naming convention to automatically map v1 DBRP combinations to a database:
Database naming examples
|v1 Database name||v1 Retention Policy name||New database name|
