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.
