v1.4.1 [2017-11-13]

Bugfixes

#9105: Fix descending cursors and range queries via IFQL RPC API.

v1.4.0 [2017-11-13]

Breaking changes

You can no longer specify a different ORDER BY clause in a subquery than the one in the top level query. This functionality never worked properly, but was not explicitly forbidden.

As part of the ongoing development of the tsi1 index, the implementation of a Bloom Filter, used to efficiently determine if series are not present in the index, was altered in #8857. While this significantly increases the performance of the index and reduces its memory consumption, the existing tsi1 indexes created while running previous versions of the database are not compatible with 1.4.0.

Users with databases using the tsi1 index must go through the following process to upgrade to 1.4.0:

Stop influxd.
Remove all index directories on databases using the tsi1 index. With default configuration these can be found in /var/lib/influxdb/data/DB_NAME/RP_NAME/SHARD_ID/index or ~/.influxdb/data/DB_NAME/RP_NAME/SHARD_ID/index. It's worth noting at this point how many different shard_ids you visit.
Run the influx_inspect inmem2tsi tool using the shard's data and WAL directories for -datadir and -waldir, respectively. Given the example in step (2) that would be influx_inspect inmem2tsi -datadir /var/lib/influxdb/data/DB_NAME/RP_NAME/SHARD_ID -waldir /path/to/influxdb/wal/DB_NAME/RP_NAME/SHARD_ID.
Repeat step (3) for each shard that needs to be converted.
Start influxd.

Users with existing tsi1 shards, who attempt to start version 1.4.0 without following the above steps, will find the shards refuse to open, and will most likely see the following error message:

incompatible tsi1 index MANIFEST

Configuration Changes

`[collectd]` Section

parse-multivalue-plugin was added with a default of split. When set to split, multivalue plugin data (e.g. df free:5000,used:1000) will be split into separate measurements (e.g., (df_free, value=5000) (df_used, value=1000)).

v1.3.0 [2017-06-21]

Release Notes

Continuous Query Statistics

When enabled, each time a continuous query is completed, a number of details regarding the execution are written to the cq_query measurement of the internal monitor database (_internal by default). The tags and fields of interest are

tag / field	description
`db`	name of database
`cq`	name of continuous query
`durationNS`	query execution time in nanoseconds
`startTime`	lower bound of time range
`endTime`	upper bound of time range
`pointsWrittenOK`	number of points written to the target measurement

startTime and endTime are UNIX timestamps, in nanoseconds.
The number of points written is also included in CQ log messages.

Removals

The admin UI is removed and unusable in this release. The [admin] configuration section will be ignored.

Configuration Changes

The top-level config bind-address now defaults to localhost:8088. The previous default was just :8088, causing the backup and restore port to be bound on all available interfaces (i.e. including interfaces on the public internet).

The following new configuration options are available.

`[http]` Section

max-body-size was added with a default of 25,000,000, but can be disabled by setting it to 0. Specifies the maximum size (in bytes) of a client request body. When a client sends data that exceeds the configured maximum size, a 413 Request Entity Too Large HTTP response is returned.

`[continuous_queries]` Section

query-stats-enabled was added with a default of false. When set to true, continuous query execution statistics are written to the default monitor store.

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

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.

v0.11.0 [2016-03-22]

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.

v0.10.0 [2016-02-04]

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.
