When working with the InfluxDB 3 Core SQL implementation a bucket is equivalent to a database, a measurement is equivalent to a table, and time, fields, and tags are structured as columns.

InfluxDB v1 to InfluxDB 3 data model

InfluxQL was designed around the InfluxDB v1 data model, but can still be used to query data from InfluxDB 3 Core. When using the InfluxDB 3 Core InfluxQL implementation, the data model is different in the following ways:

  • an InfluxDB v1 database and retention policy combination is combined into a single InfluxDB 3 database entity.
  • an InfluxDB v1 measurement is equivalent to an InfluxDB 3 table.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On April 7, 2026, 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
