v1.2.0 [2017-01-24]

Release Notes

This release introduces a major new querying capability in the form of sub-queries, and provides several performance improvements, including a 50% or better gain in write performance on larger numbers of cores.

#7661: Quote the empty string as an ident.
#7625: Fix incorrect tag value in error message.

Security

Go 1.7.4 was released to address two security issues. This release includes these security fixes.

v1.1.0 [2016-11-14]

Release Notes

This release is built with go 1.7.3 and provides many performance optimizations, stability changes and a few new query capabilities. If upgrading from a prior version, please read the configuration changes below section before upgrading.

Deprecations

The admin interface is deprecated and will be removed in a subsequent release. The configuration setting to enable the admin UI is now disabled by default, but can be enabled if necessary. We recommend using Chronograf or Grafana as a replacement.

Configuration Changes

The following configuration changes may need to changed before upgrading to 1.1.0 from prior versions.

`[admin]` Section

enabled now default to false. If you are currently using the admin interaface, you will need to change this value to true to re-enable it. The admin interface is currently deprecated and will be removed in a subsequent release.

`[data]` Section

max-values-per-tag was added with a default of 100,000, but can be disabled by setting it to 0. Existing measurements with tags that exceed this limit will continue to load, but writes that would cause the tags cardinality to increase will be dropped and a partial write error will be returned to the caller. This limit can be used to prevent high cardinality tag values from being written to a measurement.
cache-max-memory-size has been increased to from 524288000 to 1048576000. This setting is the maximum amount of RAM, in bytes, a shard cache can use before it rejects writes with an error. Setting this value to 0 disables the limit.
cache-snapshot-write-cold-duration has been decreased from 1h to 10m. This setting determines how long values will stay in the shard cache while the shard is cold for writes.
compact-full-write-cold-duration has been decreased from 24h to 4h. The shorter duration allows cold shards to be compacted to an optimal state more quickly.

Features

The query language has been extended with a few new features:

#7442: Support regex on fields keys in select clause
#7403: New linear fill option
#7388: New cumulative_sum function
#7295: Support ON for SHOW commands

v1.0.0 [2016-09-08]

Release Notes

Breaking changes

max-series-per-database was added with a default of 1M but can be disabled by setting it to 0. Existing databases with series that exceed this limit will continue to load but writes that would create new series will fail.
Config option [cluster] has been replaced with [coordinator]
Support for config options [collectd] and [opentsdb] has been removed; use [[collectd]] and [[opentsdb]] instead.
Config option data-logging-enabled within the [data] section, has been renamed to trace-logging-enabled, and defaults to false.
The keywords IF, EXISTS, and NOT where removed for this release. This means you no longer need to specify IF NOT EXISTS for DROP DATABASE or IF EXISTS for CREATE DATABASE. If these are specified, a query parse error is returned.
The Shard writePointsFail stat has been renamed to writePointsErr for consistency with other stats.

With this release the systemd configuration files for InfluxDB will use the system configured default for logging and will no longer write files to /var/log/influxdb by default. On most systems, the logs will be directed to the systemd journal and can be accessed by journalctl -u influxdb.service. Consult the systemd journald documentation for configuring journald.

Release Notes

There were some important breaking changes in this release. Here's a list of the important things to know before upgrading:

SHOW SERIES output has changed. See new output in this test diff.
SHOW TAG VALUES output has changed
JSON write endpoint is disabled by default and will be removed in the next release. You can turn it back on in this release.
b1/bz1 shards are no longer supported. You must migrate all old shards to TSM using the migration tool.
On queries to create databases, retention policies, and users, the default behavior has changed to create IF NOT EXISTS. If they already exist, no error will be returned.
On queries with a selector like min, max, first, and last the time returned will be the time for the bucket of the group by window. Selectors for the time for the specific point will be added later.

Release Notes

This release now uses the TSM storage engine. Old bz1 and b1 shards can still be read, but in a future release you will be required to migrate old shards to TSM. For new shards getting created, or new installations, the TSM storage engine will be used.

This release also changes how clusters are setup. The config file has changed so have a look at the new example. Also, upgrading a single node works, but for upgrading clusters, you'll need help from us. Sent us a note at contact@influxdb.com if you need assistance upgrading a cluster.

v0.9.3 [2015-08-26]

Release Notes

There are breaking changes in this release.

To store data points as integers you must now append i to the number if using the line protocol.
If you have a UDP input configured, you should check the UDP section of the new sample configuration file to learn how to modify existing configuration files, as 0.9.3 now expects multiple UDP inputs.
Configuration files must now have an entry for wal-dir in the [data] section. Check new sample configuration file for more details.
The implicit GROUP BY * that was added to every SELECT * has been removed. Instead any tags in the data are now part of the columns in the returned query.

Please see the Features section below for full details.
