Use the influxdb3 create file_index command to create a custom file indexing strategy for a database or table.

Provide the following:

• Token (--token): ({{< req >}}) Your {{% token-link "admin" %}}. You can also use the INFLUXDB3_AUTH_TOKEN environment variable to specify the token.
• Database (-d, --database): ({{< req >}}) The name of the database to apply the index to. You can also use the INFLUXDB3_DATABASE_NAME environment variable to specify the database.
• Table (-t, --table): The name of the table to apply the index to. If no table is specified, the indexing strategy applies to all tables in the specified database.
• Columns: ({{< req >}}) A comma-separated list of string columns to index on. These are typically tag columns but can also be string fields.
