README

runtime

The runtime a data infrastructure proxy and orchestrator – our data plane. It connects to data infrastructure and is responsible for dashboard queries, parsing code files, reconciling infra state, implementing connectors, enforcing (row-based) access policies, scheduling tasks, triggering reports, and much more.

It's designed as a modular component that can be embedded in local applications (as it is into Rill Developer) or deployed stand-alone in a cloud environment.

Code structure

The base directory contains a Runtime type that represents the lifecycle of the runtime. It ties together the sub-directories:

  • client contains a Go client library for connecting to a runtime server.
  • compilers contains logic for parsing Rill projects (incomplete, currently mostly implemented in services instead).
  • connectors contains connector implementations.
  • drivers contains interfaces and drivers for external data infrastructure that the runtime interfaces with (like DuckDB and Druid).
  • pkg contains utility libraries.
  • queries contains pre-defined analytical queries that the runtime can serve (used for profiling and dashboards).
  • server contains a server that implements the runtime's APIs.
  • testruntime contains helper functions for initializing a test runtime with test data.

Development

Developing the local application

Run rill devtool local. You need to stop and restart it using ctrl+C when you make code changes.

Developing for cloud

In one terminal, start a full cloud development environment except the runtime:

rill devtool start cloud --except runtime

In a separate terminal, start a runtime server:

go run ./cli runtime start

Optionally, deploy a seed project:

rill devtool seed cloud
Running tests

You can run all tests using:

go test ./runtime/...

Configuration

The runtime server is configured using environment variables parsed in cli/cmd/runtime/start.go.

Adding a new endpoint

We define our APIs using gRPC and use gRPC-Gateway to map the RPCs to a RESTful API. See proto/README.md for details.

To add a new endpoint:

  1. Describe the endpoint in proto/rill/runtime/v1/api.proto
  2. Re-generate gRPC and OpenAPI interfaces by running make proto.generate
  3. Copy the new handler signature from the RuntimeServiceServer interface in proto/gen/rill/runtime/v1/api_grpc_pb.go
  4. Paste the handler signature and implement it in a relevant file in runtime/server/

Adding a new analytical query endpoint

  1. Add a new endpoint for the query by following the steps in the section above ("Adding a new endpoint")
  2. Implement the query in runtime/queries by following the instructions in runtime/queries/README.md

Using a DuckDB nightly build

The following steps apply for macOS, but a similar approach should work for Linux.

  1. Download the latest DuckDB nightly from Github from the "Artifacts" section on the newest workflow run here)
  2. Unzip the downloaded archive and copy the libduckdb.dylib file in the libduckdb-osx-universal folder to /usr/local/lib
  • You must use the command-line to copy the file. If you touch it using the Finder, macOS will quarantine it. To remove a quarantine, run: xattr -d com.apple.quarantine libduckdb.dylib.
  1. DuckDB usually does not support older file formats, so delete the stage.db and stage.db.wal files in your dev-project
  2. Add the flag -tags=duckdb_use_lib when running go run or go build to use the nightly build of DuckDB
  • If testing the local frontend, you need to temporarily set it in the dev-runtime script in package.json
  • For details, see Linking DuckDB

Note: DuckDB often makes breaking changes to its APIs, so you may encounter other errors when using a dev version of DuckDB.

	Preset  map[string]string
	Project map[string]string
	Env     map[string]string
}

ConnectorConfig holds and resolves connector configuration. We support three levels of configuration: 1. Preset: provided when creating the instance (or set by the system, such as allow_host_access). Cannot be overridden. 2. Project: defined in the rill.yaml file. Can be overridden by the env. 3. Env: defined in the instance's variables (in the format "connector.name.var").

func (*ConnectorConfig) Resolve added in v0.43.0 

func (c *ConnectorConfig) Resolve() map[string]any

Resolve returns the final resolved connector configuration. It guarantees that all keys in the result are lowercase.

func (*ConnectorConfig) ResolveStrings added in v0.43.0

	Runtime    *Runtime
	InstanceID string
	Logger     *zap.Logger
	Activity   *activity.Client
	// contains filtered or unexported fields
}

Controller manages the catalog for a single instance and runs reconcilers to migrate the catalog (and related resources in external databases) into the desired state. For information about how the controller schedules reconcilers, see `runtime/reconcilers/README.md`.

func NewController added in v0.32.0 

func NewController(ctx context.Context, rt *Runtime, instanceID string, logger *zap.Logger, ac *activity.Client) (*Controller, error)

NewController creates a new Controller

func (*Controller) AcquireConn added in v0.32.0 

func (c *Controller) AcquireConn(ctx context.Context, connector string) (drivers.Handle, func(), error)

AcquireOLAP gets an OLAP handle for a connector in the controller's instance.

func (*Controller) Cancel added in v0.33.0 

func (c *Controller) Cancel(ctx context.Context, name *runtimev1.ResourceName) error

Cancel cancels the current invocation of a resource's reconciler (if it's running). It does not re-enqueue the resource for reconciliation.

func (*Controller) Create added in v0.32.0 

func (c *Controller) Create(ctx context.Context, name *runtimev1.ResourceName, refs []*runtimev1.ResourceName, owner *runtimev1.ResourceName, paths []string, hidden bool, r *runtimev1.Resource) error

Create creates a resource and enqueues it for reconciliation. If a resource with the same name is currently being deleted, the deletion will be cancelled.

func (*Controller) Delete added in v0.32.0 

func (c *Controller) Delete(ctx context.Context, name *runtimev1.ResourceName) error

Delete soft-deletes a resource and enqueues it for reconciliation (with DeletedOn != nil). Once the deleting reconciliation has been completed, the resource will be hard deleted. If Delete is called from the resource's own reconciler, the resource will be hard deleted immediately (and the calling reconcile's ctx will be canceled immediately).

func (*Controller) Flush added in v0.32.0 

func (c *Controller) Flush(ctx context.Context) error

Flush forces a flush of the controller's catalog changes to persistent storage.

func (*Controller) Get added in v0.32.0 

func (c *Controller) Get(ctx context.Context, name *runtimev1.ResourceName, clone bool) (*runtimev1.Resource, error)

Get returns a resource by name. Soft-deleted resources (i.e. resources where DeletedOn != nil) are not returned.

func (*Controller) List added in v0.32.0 

func (c *Controller) List(ctx context.Context, kind, path string, clone bool) ([]*runtimev1.Resource, error)

List returns a list of resources of the specified kind. If kind is empty, all resources are returned. Soft-deleted resources (i.e. resources where DeletedOn != nil) are not returned.

func (*Controller) Lock added in v0.32.0 

func (c *Controller) Lock(ctx context.Context)

Lock locks the controller's catalog and delays scheduling of new reconciliations until the lock is released. It can only be called from within a reconciler invocation. While the lock is held, resources can only be edited by a caller using the ctx passed to Lock.

func (*Controller) Reconcile added in v0.33.0 

func (c *Controller) Reconcile(ctx context.Context, name *runtimev1.ResourceName) error

Reconcile enqueues a resource for reconciliation. If the resource is currently reconciling, the current reconciler will be cancelled first.

func (*Controller) Run added in v0.32.0 

func (c *Controller) Run(ctx context.Context) error

Run starts and runs the controller's event loop. It returns when ctx is cancelled or an unrecoverable error occurs. Before returning, it closes the controller, so it must only be called once. The event loop schedules/invokes resource reconciliation and periodically flushes catalog changes to persistent storage. The implementation centers around these internal functions: enqueue, processQueue (uses markPending, trySchedule, invoke), and processCompletedInvocation. See their docstrings for further details.

func (*Controller) Subscribe added in v0.33.1 

func (c *Controller) Subscribe(ctx context.Context, fn SubscribeCallback) error

Subscribe registers a callback that will receive resource update events. The same callback function will not be invoked concurrently. The callback function is invoked under a lock and must not call the controller.

func (*Controller) UpdateName added in v0.33.0 

func (c *Controller) UpdateName(ctx context.Context, name, newName, owner *runtimev1.ResourceName, paths []string) error

UpdateName renames a resource and updates annotations, and enqueues it for reconciliation. If called from outside the resource's reconciler and the resource is currently reconciling, the current reconciler will be cancelled first.

func (*Controller) UpdateSpec added in v0.32.0 

func (c *Controller) UpdateSpec(ctx context.Context, name *runtimev1.ResourceName, r *runtimev1.Resource) error

UpdateSpec updates a resource's spec and enqueues it for reconciliation. If called from outside the resource's reconciler and the resource is currently reconciling, the current reconciler will be cancelled first.

func (*Controller) UpdateState added in v0.32.0 

func (c *Controller) UpdateState(ctx context.Context, name *runtimev1.ResourceName, r *runtimev1.Resource) error

UpdateState updates a resource's state. It can only be called from within the resource's reconciler. NOTE: Calls to UpdateState succeed even if ctx is cancelled. This enables cancelled reconcilers to update state before finishing.

func (*Controller) WaitUntilIdle added in v0.35.0 

func (c *Controller) WaitUntilIdle(ctx context.Context, ignoreHidden bool) error

WaitUntilIdle returns when the controller is idle (i.e. no reconcilers are pending or running).

Resolver represents logic, such as a SQL query, that produces output data. Resolvers are used to evaluate API requests, alerts, reports, etc.

A resolver has two levels of configuration: static properties and dynamic arguments. For example, a SQL resolver has a static property for the SQL query and dynamic arguments for the query parameters. The static properties are usually declared in advance, such as in the YAML for a custom API, whereas the dynamic arguments are provided just prior to execution, such as in an API request.
