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
According to the HTTP standard, a lack of authentication credentials or
incorrect authentication credentials should send back a 401
(Unauthorized) with a `WWW-Authenticate` header with a challenge that
can be used to authenticate. This is because a 401 status should be sent
when an authentication attempt can be retried by the browser.
The 403 (Forbidden) status code should be sent when authentication
succeeded, but the user does not have the necessary authorization.
Previously, the server would always send a 401 status code.
The HTTPS configuration for the httpd service only had an option to
specify the certificate file and the same file would be used for both
the certificate and private key file (they could be concatenated
together).
This adds an additional option to specify the files differently from
each other while still allowing the previous behavior. If only
`https-certificate` is specified, the httpd service will try to load the
private key from the `https-certificate` file. If a separate
`https-private-key` file is specified, the private key will be loaded
from there instead.
Fixes#1310.
These were all b1/bz1 settings that no longer have any effect:
- {Default,}MaxWALSize
- {Default,}WALFlushInterval
- {Default,}WALPartitionFlushDelay
- {Default,WAL}ReadySeriesSize
- {Default,WAL}CompactionThreshold
- {Default,WAL}MaxSeriesSize
- {Default,WAL}FlushColdInterval
- {Default,WAL}PartitionSizeThreshold
* Add dir, hostname, and bind address to top level config since it applies to services other than meta
* Add enabled flags to example toml for data and meta services
* Wire up add/remove raft peers and meta servers to meta service
* Update DROP SERVER to be either DROP META SERVER or DROP DATA SERVER
* Bring over statement executor from old meta package
* Start meta service client implementation
* Update meta service test to use the client
* Wire up node ID/meta server storage information
This makes the following syntax possible:
CREATE CONTINUOUS QUERY mycq ON mydb
RESAMPLE EVERY 1m FOR 1h
BEGIN
SELECT mean(value) INTO cpu_mean FROM cpu GROUP BY time(5m)
END
The RESAMPLE option customizes how often an interval will be sampled and
the duration. The interval is customized with EVERY. Any intervals
within the resampling duration on a multiple of the resample interval
will be updated with the new results from the query.
The duration is customized with FOR. This determines how long an
interval will participate in resampling.
Both options are optional. If RESAMPLE is in the syntax, at least one of
the two needs to be given. The default for both is the interval of the
continuous query.
The service also improves tracking of the last run time and the logic of
when a query for an interval should be run. When determining the oldest
interval to run for a query, the continuous query service determines
what would have been the optimal time to perform the next query based on
the last run time. It then uses this time to determine the oldest
interval that should be run using the resample duration and will
resample all intervals between this time and the current time as opposed
to potentially forgetting about the last run in an interval if the
continuous query service gets delayed for some reason.
This removes the previous config options for customizing continuous
queries since they are no longer relevant and adds a new option of
customizing the run interval. The run interval determines how often the
continuous query service polls for when it should execute a query. This
option defaults to 1s, but can be set to 1m if the least common factor
of all continuous queries' intervals is a higher value (like 1m).
* Update Plan to do a full compaction if cold for writes
* Remove MaxFileSize as a config variable from Compactor. Should be a set constant
* Update Plan to keep track of if the last check was fully compacted so we can skip future planning calls
* Update compact min file count to 3 so that compactions run more frequently
* remove rolloverTSMFileSize constant that is no longer used
* remove the maxGenerationFileCount since it is no longer a limitation that's necessary with the new compaction scheme. We no longer read WAL segments as part of the compaction so memory is only used as we read in each individual key
* remove minFileCount and switch to a user configurable variable
* remove the mutex from WALSegmentWriter. There's never more than one open in the WAL at one time and it's not exported through any function so the lock on the WAL should be used. This simplified keeping track of the last write time and removed a bunch of unnecessary locks.
* update WALSegmentWriter.Write to take the compressed bytes so that encoding and compression can occur before the call to write (while we don't hold the WAL lock)
* remove a bunch of unnecessary locking in WAL.writeToLog
* Add check for TSM file magic number and vesion
* Remove old tsm, log, and unused cursor code
* Remove references to tsm1dev everywhere except in the inspector
* Clean up config options for compaction and snapshotting
* Remove old TSM configuration options
* Update the config.sample.toml with TSM options
* Update WAL compact to force if it has been cold for writes for a configurable period of time (1h by default)
New package filesystem hierarchy:
- /var/lib/influxdb => Data directories
- /usr/lib/influxdb => Scripts and other miscellaneous files
- /etc/influxdb => Configuration
- /usr/bin/ => Where InfluxDB binaries will live
Registration also involves statistics and diagnostics upload, for the
purposes of remote management. This means there will be long-running
goroutines in effect. Therefore move the code to a service model.
