Differences between InfluxDB 1.4 and 1.3

This page documents an earlier version of InfluxDB. InfluxDB v2.6 is the latest stable version.

This page aims to ease the transition from InfluxDB 1.3 to InfluxDB 1.4. For a comprehensive list of the differences between the versions see InfluxDB’s Changelog.

Content

TSI release

Version 1.3.0 marked the first official release of InfluxDB’s new time series index (TSI) engine. Additional improvements have been made to the TSI engine for 1.4.

With TSI, the number of series should be unbounded by the memory on the server hardware and the number of existing series will have a negligible impact on database startup time. See Paul Dix’s blogpost Path to 1 Billion Time Series: InfluxDB High Cardinality Indexing Ready for Testing for additional information.

Note: TSI remains disabled by default in version 1.4. We do not recommend using this setting for production deployments at this time. This feature is considered experimental and feedback is welcome.

To enable TSI, uncomment the index-version setting and set it to tsi1. The index-version setting is in the [data] section of the configuration file. Next, restart your InfluxDB instance.
