Write to MariaDB

To write data to MariaDB with Flux:

  1. Import the sql package.

  2. Pipe-forward data into and provide the following parameters:

    • driverName: mysql
    • dataSourceName: See data source name
    • table: Table to write to
    • batchSize: Number of parameters or columns that can be queued within each call to Exec (default is 10000)
import "sql"

        driverName: "mysql",
        dataSourceName: "user:password@tcp(localhost:3306)/db",
        query: "SELECT * FROM example_table",

MariaDB data source name

The mysql driver uses the following data source name (DSN) syntax (also known as a connection string):


Flux to MariaDB data type conversion converts Flux data types to MariaDB data types.

MariaDB BOOL types

BOOL is a synonym supplied by MariaDB for convenience. MariaDB stores BOOL values as TINYINT types so looking at the schema shows the column type as TINYINT.

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
