This is a backport of #14262 to the 1.x storage engine.
This also ports the table tests that existed with the pre-beta version of the
storage engine to the one that is now used in the production version.
A few of the tests are skipped. These are portions of the storage engine
that have not been ported over. They should be unskipped when that
functionality is ported over.

Meta queries (SHOW TAG VALUES, SHOW TAG KEYS, SHOW SERIES CARDINALITY, etc.) do not respect
the QueryTimeout config parameter. Meta queries should check the query context when possible
to allow cancellation and timeout. This will not be as frequent as regular queries, which
use iterators, because meta queries return data in batches.
Add a context.Context to
(*Store).MeasurementNames()
(*Store).MeasurementsCardinality()
(*Store).SeriesCardinality()
(*Store).TagValues()
(*Store).TagKeys()
(*Store).SeriesSketches()
(*Store).MeasurementsSketches()
which is tested for timeout or cancellation
to allow limitation of time spent in meta queries

The flux in influxdb has been upgraded to use v0.33.2. A lot of
interfaces for the storage engine were changed during this so code had
to change to accomodate the new interfaces and remove the old ones.
Included in this commit is a patch file for the changes that were made.
A patch was generated for the following packages:
* `flux/stdlib/influxdata/influxdb`
* `storage/reads`
* `tsdb/cursors`
These are the three packages that are in common with version 2 of the
database and the first of these packages contains the specific
implementations that are used for version 1.
It is very possible that the next time we upgrade this, the patch will
not apply cleanly just like it wouldn't have applied cleanly to this
update. The patch is mostly meant to document exactly what changed
during the copy over to help ensure we don't forget things when adapting
the interfaces.
Add a patch file to hopefully make this easier in the future
This integrates the influxdb 1.x series to the latest version of Flux
and updates the code to use it. It also removes the dependency on
platform and copies the necessary code from storage into the 1.x series
so the dependency is unneeded.
The flux functions specific to 1.x have been moved to the same structure
that flux changed to with having a `stdlib` directory instead of a
`functions` directory. It also adds a `databases()` function that
returns the databases from the meta client.
This commit deletes most of the code to service reads from influxdb
and pulls it in from platform instead.
Of note, the models.Tag and models.Tags types are now aliases to the
platform models.Tag and models.Tags types. Additionally, many types
in the tsdb package relating to cursors are also aliases to the same
types in the platform cursors package.
This updates the platform and flux repos to the current master in the
Gopkg.lock.
* the protocol service definition, ReadRequest and ReadResponse is
reused across projects, rather than requiring redefinition.
* the ReadRequest protocol buffer definition removes the concept of a
database and retention policy, replacing it with a field named
ReadSource of type google.protobuf.Any. OSS requests will use the
ReadSource message structure defined in local to this package, which
defines fields to represent a Database and RetentionPolicy. Other
implementations can provide their own data structure allowing the
remainder of the ReadRequest to be reused.
* The RPC service and Store are expected to be redefined to handle their
specific requirements for resolving a ReadSource
* ResultSet and GroupResultSet are interfaces representing non-grouping
and grouping read behavior respectively. Calling NewResultSet or
NewGroupResultSet will construct instances of these types
* The ResponseWriter type is exported to deal with serialization of
the ResultSet and GroupResultSet types
Since possibly v0.9 DELETE SERIES has had the unwanted side effect of
removing series from the index when the last traces of series data are
removed from TSM. This occurred because the inmem index was rebuilt on
startup, and if there was no TSM data for a series then there could be
not series to add to the index.
This commit returns to the original (documented) DROP/DETETE SERIES
behaviour. As such, when issuing DROP SERIES all instances of matching
series will be removed from both the TSM engine and the index. When
issuing DELETE SERIES only TSM data will be removed.
It is up to the operator to remove series from the index.
NB, this commit does not address how to remove series data from the
series file when a shard rolls over.
The previous sha was taken from a revision on a devel branch that I
thought would continue staying in the tree after it was merged. That
revision was rebased away and the API was changed for the logger.
This updates the usage of the logger and adds a simple package for
constructing the base logger.
The 1.0 version of zap changed the format of the default console logger
so this change moves over to this new logger instead of attempting to
retain backwards compatibility with the old format.
This commit adds time support to SHOW TAG VALUES. Time can be used as
both a lower and upper boundary. However, there are some caveats.
For the `inmem` index, filtering by time will still return all results
because the index data is shared across shards.
For the `tsi1` index, filtering by time will only work down to the shard
lever. Specifically, when querying by time all shards within that time
range will be used to generate the results.
Fixes#8819.
Previously, the process of dropping expired shards according to the
retention policy duration, was managed by two independent goroutines in
the retention policy service. This behaviour was introduced in #2776,
at a time when there were both data and meta nodes in the OSS codebase.
The idea was that only the leader meta node would run the meta data
deletions in the first goroutine, and all other nodes would run the
local deletions in the second goroutine.
InfluxDB no longer operates in that way and so we ended up with two
independent goroutines that were carrying out an action that was really
dependent on each other.
If the second goroutine runs before the first then it may not see the
meta data changes indicating shards should be deleted and it won't
delete any shards locally. Shortly after this the first goroutine will
run and remove the meta data for the shard groups.
This results in a situation where it looks like the shards have gone,
but in fact they remain on disk (and importantly, their series within
the index) until the next time the second goroutine runs. By default
that's 30 minutes.
In the case where the shards to be removed would have removed the last
occurences of some series, then it's possible that if the database was already at its
maximum series limit (or tag limit for that matter), no further new series
can be inserted.
This adds query syntax support for subqueries and adds support to the
query engine to execute queries on subqueries.
Subqueries act as a source for another query. It is the equivalent of
writing the results of a query to a temporary database, executing
a query on that temporary database, and then deleting the database
(except this is all performed in-memory).
The syntax is like this:
SELECT sum(derivative) FROM (SELECT derivative(mean(value)) FROM cpu GROUP BY *)
This will execute derivative and then sum the result of those derivatives.
Another example:
SELECT max(min) FROM (SELECT min(value) FROM cpu GROUP BY host)
This would let you find the maximum minimum value of each host.
There is complete freedom to mix subqueries with auxiliary fields. The only
caveat is that the following two queries:
SELECT mean(value) FROM cpu
SELECT mean(value) FROM (SELECT value FROM cpu)
Have different performance characteristics. The first will calculate
`mean(value)` at the shard level and will be faster, especially when it comes to
clustered setups. The second will process the mean at the top level and will not
include that optimization.
