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

The postgres driver uses the Go pq implementation to interact with CockroachDB.

Flux to CockroachDB data type conversion

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

Flux data type CockroachDB data type
float FLOAT
int BIGINT
uint BIGINT
string TEXT
bool BOOL
time TIMESTAMP

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.

For information about the future of Flux, see the following:
