* refactor: use repository in catalog
The catalog was refactored to use identifiers on everything, and store
everything in a consistent structure. This structure makes use of the
`Repository` type that holds a `SerdeVecMap` of Id to Resource, along
with the next Id, and a bi-map of Id to resource name.
The `Repository` type is used at each level of the catalog where a
resource is stored.
This simplified repeated logic for snapshot'ing, insert and update of
resources in the catalog, as well as accessor methods for getting by id
or name, and mapping names to ids and vice-versa.
In addition, the process for catalog batch verification and permit was
altered so that the permit process induces a retry if the catalog was
updated while the catalog batch function was producing the batch, i.e, if
the catalog sequence incremented while the caller was waiting for a permit.
This eliminated the need for verifying the catalog batch after it had been
generated, and allows for a single path to apply a catalog batch after it
has been persisted to object store.
This assumes that the generation of the catalog batch implies validity.
Irelevant tests were removed.
Last and Distinct cache's now rely more heavily on Ids, though the proc-
essing engine still needs to switch over to use Ids for starting/stopping
triggers.
In #25927 we missed that JSON queries were broken despite having some
tests use the format. This fixes JSON queries such that they now
properly contain a comma between RecordBatches. This commit also
includes tests for the formats that now stream data back (CSV, JSON, and
JSON Lines) so that we won't run into this issue again.
* deduplicate QueryParams->QueryRequest and Format->QueryFormat
* move WriteParams into influxdb3_types crate
* DRY up client HTTP request handling code in *RequestBuilder.send
methods.
* DRY up a bunch of other non-Builder http request handling
Partially fixes https://github.com/influxdata/influxdb/issues/24672
* move most HTTP req/resp types into `influxdb3_types` crate
* removes the use of locally-scoped request type structs from the `influxdb3_client` crate
* fix plugin dependency/package install bug
* it looks like the `DELETE` http method was being used where `POST` was expected for `/api/v3/configure/plugin_environment/install_packages` and `/api/v3/configure/plugin_environment/install_requirements`
This commit allows us to stream data back for CSV and JSON formatted
queries. Prior to this we would buffer up all of the data in memory
before sending it back. Now we can make it so that we only buffer in
one RecordBatch at a time to reduce memory overhead.
Note that due to the way the APIs for writers work and for how Body in
hyper 0.14 works we can't use a streaming body that we can write too.
This in turn means we have to use a manually written Future state
machine, which works but is far from ideal.
Note this does not include the pretty and parquet files as streamable.
I'm attempting to get the pretty one to be streamable, but I don't think
that this one and parquet are as likely to be streamable back to the
user. In general we might want to discourage these formats from being
used.
This updates trigger creation to load the plugin file before creating the trigger.
Another small change is to make Github references use filenames and paths identical to what they would be in the plugin-dir. This makes it a little easier to have the plugins repo local and develop against it and then be able to reference the same file later with gh: once it's up on the repo.
This refactors plugins and triggers so that plugins no longer need to be "created". Since plugins exist in either the configured local directory or on the Github repo, a user now only needs to create a trigger and reference the plugin filename.
Closes#25876
* feat: first stab at locally updating parquet cache
closes: https://github.com/influxdata/influxdb/issues/25887
* refactor: use enums to separate out the modes
This commit introduced the `Immediate` and `Eventual` modes for
fulfilling the cache request. In immediate mode since the data is
readily available to be cached, we can avoid extra requests to object
store.
part of: https://github.com/influxdata/influxdb/issues/25887
This commit does a few key things:
- Removes the 72 hour query and write restrictions in Core
- Limits the queries to a default number of parquet files. We chose 432
as this is about 72 hours using default settings for the gen1
timeblock
- The file limit can be increased, but the help text and error message
when exceeded note that query performance will likely be degraded as
a result.
- We warn users to use smaller time ranges if possible if they hit this
query error
With this we eliminate the hard restriction we have in place, but
instead create a soft one that users can choose to take the performance
hit with. If they can't take that hit then it's recomended that they
upgrade to Enterprise which has the compactor built in to make
performant historical queries.
* refactor: reduce catalog locks when getting chunks
The main refactor was to change the ChunkContainer trait to use the
DatabaseSchema and TableDefinition types directly in the signature, vs.
the names, which then required an additional catalog lock and lookups for
both entities. This was already handled upstream in the QueryTable, so
there was no need to do the lookups again.
This required the addition of a test helper in influxdb3_write::test_helpers
that provides convenience methods for getting record batches from the
WriteBuffer. We have been implementing such a method manually in several
places, so this is nice to have it unified. This provides a blanket impl
so that anything implementing WriteBuffer gets the method.
Some other house cleaning was included.
* refactor: clean up test helpers in influxdb3_write
* refactor: pass original df filters forward with ChunkFilter
* chore: clippy
* feat: Add request plugin capability
Adds the request plugin type. Triggers can be bound to an API endpoint at /api/v3/engine/<path>. Requests will get yielded to the plugin with the query parameters, request parameters, and request body.
I didn't implement the test endpoint for this plugin type as it seems much more natural for users to save the file and make a new request. Once #25863 is done it'll make it very easy.
Closes#25862
* chore: fix spelling in error message
Although the `format` in the request is used, the value coming
through the header is parsed earlier. So, when that lookup in
the header fails an error is returned (`InvalidMimeType`).
In this commit, there are extra checks to allow the default `Accept`
header values that come from the browser by defaulting it to `json`

* feat(processing_engine): Add cron plugins and triggers to the processing engine.
* feat(processing_engine): switch from 'cron plugin' to 'schedule plugin', use TimeProvider.
* feat(processing_engine): add test for test scheduled plugin.
This updates the v1 /query API hanlder to handle InfluxDB v1's unique
query response structure when GROUP BY clauses are provided.
The distinction is in the addition of a "tags" field to the emitted series
data that contains a map of the GROUP BY tags along with their distinct
values associated with the data in the "values" field.
This required splitting the QueryExecutor into two query paths for InfluxQL
and SQL, as this allowed for handling InfluxQL query parsing in advance
of query planning.
A set of snapshot tests were added to check that it all works.
This changes the CLI arg `host-id` to `writer-id` to more accurately
indicate meaning.
This changes also goes through the codebase and changes struct fields,
methods, and variables to use the term `writer_id` or `writer_identifier_prefix`
instead of `host_id` etc., to make the meaning clear in the code.
This also changes the catalog serialization to use the field `writer_id`
instead of `host_id`, which is breaking change.
This updates the create plugin API and CLI so that it doesn't take the pugin code, but instead takes a file name of a file that must be in the plugin-dir of the server. It returns an error if the plugin-dir is not configured or if the file isn't there.
Also updates the WAL and catalog so that it doesn't store the plugin code directly. The code is read from disk one time when the plugin runs.
Closes#25797
* feat: introduce num wal files to keep
This commit allows a configurable number of wal files to be left behind
in OS. This is necessary as enterprise replicas rely on these files.

This allows the user to specify arguments that will be passed to each execution of a wal plugin trigger. The CLI test was updated to check this end to end.
Closes#25655
This updates the WAL so that it can have new file notifiers added that will get updated when the wal flushes. The processing engine now implements the WALNotifier trait.
I've updated the CLI test for creating a trigger to run and end-to-end test that defines a plugin, creates a trigger, writes data into the database, triggering the plugin, which writes summary statistics back into the database in a different table. The test queries the destination table to confirm that the plugin worked.
* feat: Update WAL plugin for new structure
This ended up being a very large change set. In order to get around circular dependencies, the processing engine had to be moved into its own crate, which I think is ultimately much cleaner.
Unfortunately, this required changing a ton of things. There's more testing and things to add on to this, but I think it's important to get this through and build on it.
Importantly, the processing engine no longer resides inside the write buffer. Instead, it is attached to the HTTP server. It is now able to take a query executor, write buffer, and WAL so that the full range of functionality of the server can be exposed to the plugin API.
There are a bunch of system-py feature flags littered everywhere, which I'm hoping we can remove soon.
* refactor: PR feedback
This ended up being a couple things rolled into one. In order to add a query API to the Python plugin, I had to pull the QueryExecutor trait out of server into a place so that the python crate could use it.
This implements the query API, but also fixes up the WAL plugin test CLI a bit. I've added a test in the CLI section so that it shows end-to-end operation of the WAL plugin test API and exercise of the entire Plugin API.
Closes#25757
* feat: snapshot when wal buffer is empty
- This commit changes the functionality to allow snapshots to happen even when
wal buffer is empty. For snapshots wal periods are still required but
not the wal buffer. To allow this, we write a no-op into wal file with
snapshot details. This enables force snapshotting functionality

Closes#25749
This changes the `/query` API handler so that the parameters can be passed in either the request URI or in the request body for either a `GET` or `POST` request.
Parameters can be specified in the URI, the body, or both; if they are specified in both places, those in the body will take precedent.
Error variants in the HTTP server code related to missing request parameters were updated to return `400` status.
