Changes the default time boundaries for raw queries so raw queries will
range until the end of time. Aggregate queries continue to have their
default end time be `now()`.
The information in the usage string for the `help` command about
how to get more information about a specific command was incorrect:
"influxd help [command]" does not work, but "influxd [command] --help"
does.
If you pipe in a file to the `influx` CLI, it will not try to open the
interactive line reader, but instead just send the contents of the
entire file to the server.
The `cumulative_sum()` function can be used to sum each new point and
output the current total. For the following points:
cpu value=2 0
cpu value=4 10
cpu value=6 20
This would output the following points:
> SELECT cumulative_sum(value) FROM cpu
time value
---- -----
0 2
10 6
20 12
As can be seen, each new point adds to the sum of the previous point and
outputs the value with the same timestamp.
The function can also be used with an aggregate like `derivative()`.
> SELECT cumulative_sum(mean(value) FROM cpu WHERE time >= now() - 10m GROUP BY time(1m)
The tags passed into Statistics() calls are not supposed to be modified.
The balanceWriter in subscribers tried to modify them triggering a panic
because they can be nil.
The vet checks for some files did not pass for go 1.7. As part of a
preliminary start to making go 1.7 work with this software, go vet
should pass.
Also updated the gogo/protobuf dependency which fixed the code generator
to work with go 1.7 too. Ran `go generate` on the entire repository to
ensure every file was up to date.
There were three different outputs that could be output with columns
that were rather strange depending on if there was a name and if there
were tags with the response.
Normalized output now has the dashes always under the column names and
no dashes anywhere else for consistency.
- Single commit, PR follows conventions laid out by @Gouthamve in #5822
* main.go: struct field CpuFile should be CPUFile
* influx_inspect: loop equivalent to `for key := range...`
* adds comments to exported fields and consts
* fixes typo in `CHANGELOG.md`: text for #4702 now matches number
It is now possible to use a mixed duration unit like `1h30m`. The
duration units can be in whatever order as long as they are connected to
each other.
There is a change to the scanner. A token such as `10x` will be scanned
as a duration literal, but will then fail to parse as an invalid
duration. This should not be a breaking change as there is no situation
where `10m10` was a valid order of tokens for the parser.
Fixes#3634.
Instead of having the parser set the defaults, the command will set the
defaults so that the constants for that are actually used. This way we
can also identify which things the user provided and which ones we are
filling with default values.
This allows the meta client to be able to make smarter decisions when
determining if the user requested a conflict or if the requested
capabilities match with what is currently available. If you just say
`CREATE DATABASE WITH NAME myrp`, the user doesn't really care what the
duration of the retention policy is and just wants to use the default.
Now, we can use that information to determine if an existing retention
policy would conflict with what the user requested rather than returning
an error if a default value ever gets changed since the meta client
command can communicate intent more easily.
This commit fixes the `MaxSelectSeriesN` limit which was broken by
the implementation of lazy iterators. The setting previously limited
the total number of series but the new implementation limits the
concurrent number of series being processed.
