Write to SQLite

To write data to SQLite with Flux:

  1. Import the sql package.

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

    • driverName: sqlite3
    • 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 (set to 999 or less)
import "sql"

data
    |> sql.to(
        driverName: "sqlite3",
        dataSourceName: "file:/path/to/example.db?cache=shared&mode=ro",
        table: "example_table",
    )

Requires file system access

To query SQLite, Flux must have access to the filesystem. If Flux does not have access to the file system, the query will return an error similar to one of the following:

  • Error: unable to open database file
  • failed to read file: filesystem service is uninitialized
  • An internal error has occurred

If using InfluxDB Cloud or InfluxDB OSS, the Flux process does not have access to the filesystem.


SQLite data source name

The sqlite3 driver uses the following DSN syntax (also known as a connection string):

file:/path/to/example.db?param=value

Flux to SQLite data type conversion

sql.to() converts Flux data types to SQLite data types.

New in InfluxDB 3.5

Key enhancements in InfluxDB 3.5 and the InfluxDB 3 Explorer 1.3.

See the Blog Post

InfluxDB 3.5 is now available for both Core and Enterprise, introducing custom plugin repository support, enhanced operational visibility with queryable CLI parameters and manual node management, stronger security controls, and general performance improvements.

InfluxDB 3 Explorer 1.3 brings powerful new capabilities including Dashboards (beta) for saving and organizing your favorite queries, and cache querying for instant access to Last Value and Distinct Value caches—making Explorer a more comprehensive workspace for time series monitoring and analysis.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On November 3, 2025, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
