influxdata/influxdb v2.0.5

on GitHub

v2.0.5 [2021-04-27]

WARNING

influxd upgrade will generate an invalid v2 config file in this release if:

1. It is passed the --config-file option, AND
2. The v1 config pointed to by --config-file contains a setting for coordinator.max-concurrent-queries

In this case, users will see this error when attempting to boot up their v2 server:

Error: invalid controller config: QueueSize must be positive when ConcurrencyQuota is limited

A patch release containing a fix for this issue will be released ASAP. In the meantime, users who encounter this error can fix the issue by modifying their config in one of two ways:

1. Set query-concurrency to 0, OR
2. Set query-queue-size to a value greater than 0

Binary Packages

Windows Support

This release includes our initial Windows preview build.

Breaking Changes

/debug/vars removed

Prior to this release, the influxd server would always expose profiling information over /debug/vars.
This endpoint was unauthenticated, and not used by InfluxDB systems to report diagnostics. For security and clarity,
the endpoint has been removed. Use the /metrics endpoint to collect system statistics.

influx transpile removed

The transpile command has been retired. Users can send InfluxQL directly to the server via the /api/v2/query
or /query HTTP endpoints.

Default query concurrency changed

The default setting for the max number of concurrent Flux queries has been changed from 10 to unlimited. Set the
query-concurrency config parameter to > 0 when running influxd to re-limit the maximum running query count,
and the query-queue-size config parameter to > 0 to set the max number of queries that can be queued before the
server starts rejecting requests.

Prefix for query-controller metrics changed

The prefix used for Prometheus metrics from the query controller has changed from query_control_ to qc_.
