The subscriber write goroutine would drop points if the write load
was higher than it could process. This could happen with a just
a few writers to the server.
Instead, process the channel with multiple writers to avoid dropping
writes so easily. This also adds some config options to control how
large the channel buffer is as well as how many goroutines are started.
Fixes#7330
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.
Truncate the time interval output of the monitor service to be on even
time intervals rather than on every minute based on the start time. This
normalizes the output from the monitor service.
This has various benefits:
- Users embedding InfluxDB within other Go programs can specify a different logger / prefix easily.
- More consistent with code used elsewhere in InfluxDB (e.g. services, other `run.Server.*` fields, etc).
- This is also more efficient, because it means `executeQuery` no longer allocates a single `*log.Logger` each time it is called.
Go style -- and existing runtime stats -- do not use underscores, but
instead use camel case. This change makes the internal stats adhere to
that convention.
