0.11 no longer uses some files from 0.10. The code was a little
too aggressive and remove these files which would break rolling back
to 0.10 if necessary. Since shards must be migrated to tsm before
upgrading to 0.11 and a user might not know they still have old shard
formats, they would not be able to revert back to 0.11 and migrate
them.
Also adds uptime stats to usage data.
`SHOW TAG VALUES` output has been modified to print the measurement name
for every measurement and to return the output in two columns: key and
value. An example output might be:
> SHOW TAG VALUES WITH KEY IN (host, region)
name: cpu
---------
key value
host server01
region useast
name: mem
---------
key value
host server02
region useast
`measurementsByExpr` has been taught how to handle reserved keys (ones
with an underscore at the beginning) to allow reusing that function and
skipping over expressions that don't matter to the call.
Fixes#5593.

Fixes#5612, #5573 and #5518.
Using the MetaExecuter, queries that need to run on both data nodes
and optionally the meta store will be executed across all data nodes
in the cluster.
This fixes a regression introduced in #5757 due to the node.ID getting
assigned by both the meta and data services. When both roles are active,
the data CreateDataNode path was not getting called because a node ID was
already assigned.
This fixes the issue by seeing if a DataNode already exists for our node
ID, and if it does not, we create one.
This fixes a couple of issues with starting meta-only nodes.
1. We were always calling CreateDataNode regardless of whether the the
node is running data services. We only call that now when node is
data enabled.
2. The node.json was created along-side creating the data node. Since
we are not creatinga a data node, this didn't happen anymore. There
wasn't a simple way to do this in one place so it's actually handle
for when creating a meta or a data node now. Since the ID assigned
to the node is the same regardless of role this works in all combinations
of roles.
3. The JoinMetaServer didn't return the ID of the joining node which
created some races when multiple nodes were joining. The join call now
returns that information to the caller.
Fixes#5754
The join option was incorrectly exposed on the meta config. It should
be at the top-level as a string and propogate down to the meta config
as a slice.
This fixes several issues related to the bind address and hostname:
* Allows bind addresses where a hostname or IP is not specified to
work correct and bind to all interfaces by default.
* Fixes the top-level "hostname" config option to allow overridding
all bind address hostnames. This allows a node to advertise a different
hostname than what is defined in the bind address setting.
* Adds the -hostname command-line option back to allow specifing
both -join and -hostname as command-line flags.
* Enforces a configuration precedence and overriding ability defined
as config file is overridden by env vars which are overriden by command-line
flags.
Fixes#5670#5671
The name of the column will be every measurement located inside of the
math expression in the order they are encountered in within the
expression.
Also handle `*influxql.ParenExpr` in the function
`(*influxql.Field).Name()`
Fixes#5730.
Previously, meta.Client would drop the default retention policy when
trying to create a database with a retention policy. The RPC has now
been modified to include the desired retention policy in the
CreateDatabase command and have it use that retention policy information
instead of the default configuration when provided.
This also lowers the number of RPC calls for
CreateDatabaseWithRetentionPolicy to only a single RPC call instead of
two.
Protections have also been included so creating a retention policy with
different parameters will return an error similar to if you tried to
modify the retention policy separately.
Fixes#5696.
This removes the MetaServers property from node.json to eliminate one
of the four places those addresses are stored on disk. We always use
the values that come through the config (via file, env var or -join arg).
top() and bottom() point ordering was incorrect and using an inefficient
method of sorting. It has now been updated to use a heap and ordering is
being done by value first and time second (with earlier times always
taking priority).
Removed unit tests that test using `time` inside of the query to get the
real time instead of the interval time and only allowing the default
behavior. We will have another mechanism to get the real time during an
interval, but the current method is deprecated.
The top() and bottom() methods now have integer support.
