Create a database

Use the influxdb3 create database command to create a database in InfluxDB 3 Core. Provide the following:

• Database name (see Database naming restrictions)

• InfluxDB 3 Core authorization token

  While in beta, InfluxDB 3 Core does not require an authorization token.

• InfluxQL DBRP naming convention
• Database limit

Database naming restrictions

Database names must adhere to the following naming restrictions:

• Alphanumeric characters
• Dashes (-), underscores (_), and forward slashes (/) are allowed
• Must start with a letter or number
• Maximum length of 64 characters

InfluxQL DBRP naming convention

In InfluxDB 1.x, data is stored in databases and retention policies. In InfluxDB 3 Core, databases and retention policies have been merged into databases; retention policies are no longer part of the data model. Because InfluxQL uses the 1.x data model, to support InfluxQL queries the use databases and retention policies, an InfluxDB 3 Core 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 an InfluxDB 3 Core database:

database_name/retention_policy_name
