More information on contributing is in 37 | the [Contribution Guide](https://github.com/apache/datafusion-ballista/blob/main/CONTRIBUTING.md) 38 | , and we have curated a [good-first-issue](https://github.com/apache/datafusion-ballista/contribute) 39 | list to help you get started. You can find datafusion's major designs in docs/source/specification. 40 | 41 | We use GitHub issues for maintaining a queue of development work and as the 42 | public record. We often use Google docs, Github issues and pull requests for 43 | quick and small design discussions. For major design change proposals, we encourage you to write a rfc. 44 | -------------------------------------------------------------------------------- /ballista/scheduler/src/api/mod.rs: -------------------------------------------------------------------------------- 1 | // Licensed under the Apache License, Version 2.0 (the "License"); 2 | // you may not use this file except in compliance with the License. 3 | // You may obtain a copy of the License at 4 | // 5 | // http://www.apache.org/licenses/LICENSE-2.0 6 | // 7 | // Unless required by applicable law or agreed to in writing, software 8 | // distributed under the License is distributed on an "AS IS" BASIS, 9 | // WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 10 | // See the License for the specific language governing permissions and 11 | // limitations under the License. 12 | 13 | mod handlers; 14 | 15 | use crate::scheduler_server::SchedulerServer; 16 | use axum::routing::patch; 17 | use axum::{routing::get, Router}; 18 | use datafusion_proto::logical_plan::AsLogicalPlan; 19 | use datafusion_proto::physical_plan::AsExecutionPlan; 20 | use std::sync::Arc; 21 | 22 | pub fn get_routes< 23 | T: AsLogicalPlan + Clone + Send + Sync + 'static, 24 | U: AsExecutionPlan + Send + Sync + 'static, 25 | >( 26 | scheduler_server: Arc>, 27 | ) -> Router { 28 | let router = Router::new() 29 | .route("/api/state", get(handlers::get_scheduler_state::)) 30 | .route("/api/executors", get(handlers::get_executors::)) 31 | .route("/api/jobs", get(handlers::get_jobs::)) 32 | .route("/api/job/{job_id}", patch(handlers::cancel_job::)) 33 | .route( 34 | "/api/job/{job_id}/stages", 35 | get(handlers::get_query_stages::), 36 | ) 37 | .route( 38 | "/api/job/{job_id}/dot", 39 | get(handlers::get_job_dot_graph::), 40 | ) 41 | .route( 42 | "/api/job/{job_id}/stage/{stage_id}/dot", 43 | get(handlers::get_query_stage_dot_graph::), 44 | ) 45 | .route("/api/metrics", get(handlers::get_scheduler_metrics::)); 46 | 47 | #[cfg(feature = "graphviz-support")] 48 | let router = router.route( 49 | "/api/job/{job_id}/dot_svg", 50 | get(handlers::get_job_svg_graph::), 51 | ); 52 | 53 | router.with_state(scheduler_server) 54 | } 55 | -------------------------------------------------------------------------------- /docs/source/user-guide/scheduler.md: -------------------------------------------------------------------------------- 1 | 19 | 20 | # Ballista Scheduler 21 | 22 | ## REST API 23 | 24 | The scheduler also provides a REST API that allows jobs to be monitored. 25 | 26 | > This is optional scheduler feature which should be enabled with `rest-api` feature 27 | 28 | | API | Method | Description | 29 | | ------------------------------------ | ------ | ----------------------------------------------------------------- | 30 | | /api/jobs | GET | Get a list of jobs that have been submitted to the cluster. | 31 | | /api/job/{job_id} | GET | Get a summary of a submitted job. | 32 | | /api/job/{job_id}/dot | GET | Produce a query plan in DOT (graphviz) format. | 33 | | /api/job/:job_id/dot_svg | GET | Produce a query plan in SVG format.
