This page aims to ease the transition from InfluxDB 1.1 to InfluxDB 1.2. For a comprehensive list of the differences between the versions see InfluxDB’s Changelog.
Version 1.2 offers a significantly improved underlying data cache. The improvements yield a 50% write performance boost under load, allowing users to rapidly store even more data than before.
New Query Capabilities
InfluxDB has extended its query language to support subqueries. Subqueries allow users to be more efficient in finding insights into their data. See the Data Exploration page for a detailed syntax description and practical examples.
With version 1.2, the Command Line Interface (CLI) offers new functionality that simplifies writing and querying data in InfluxDB.
USEsupports specifying a target retention policy with
USE "database_name"."retention policy_name"
CLEARclears the current target database or retention policy
INSERT INTO "retention policy"no longer resets the target retention policy for every subsequent write
The admin UI (port
8083) remains officially deprecated and disabled in this release.
It can be re-enabled in the configuration file, but will be removed in a future release.
We recommend using Chronograf or Grafana as a replacement.
This release is a drop-in replacement for 1.1 with no data migration required. There are some configuration changes that may need to be updated prior to upgrading to avoid downtime. Be sure to read the CHANGELOG prior to upgrading.
