Write to CockroachDB

To write data to CockroachDB with Flux:

1. Import the sql package.

2. Pipe-forward data into sql.to() and provide the following parameters:

   • driverName: postgres
   • 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"

data
    |> sql.to(
        driverName: "postgres",
        dataSourceName:
            "postgresql://username:password@localhost:26257/cluster_name.defaultdb?sslmode=verify-full&sslrootcert=certs_dir/cc-ca.crt",
        table: "example_table",
    )

CockroachDB data source name

The postgres driver uses the following DSN syntax (also known as a connection string):

postgres://username:password@localhost:26257/cluster_name.defaultdb?sslmode=verify-full&sslrootcert=certs_dir/cc-ca.crt

{{% note %}} The postgres driver uses the Go pq implementation to interact with CockroachDB. {{% /note %}}

Flux to CockroachDB data type conversion

sql.to() converts Flux data types to PostgreSQL and CockroachDB data types.
