+# Data requests
+
+[BackendSrv](https://grafana.com/docs/grafana/latest/packages_api/runtime/backendsrv) handles all outgoing HTTP requests from Grafana. This document explains the high-level concepts used by `BackendSrv`.
+
+## Canceling requests
+This section describes how canceling requests work in Grafana. While data sources can implement their own cancellation concept, we recommend that you use the method we describe here.
+
+A data request can take a long time to finish. During the time between when a request starts and finishes, the user can change context. For example, the user may navigate away or issue the same request again.
+
+If we wait for canceled requests to complete, it might create unnecessary load on data sources.
+
+Grafana uses a concept called _request cancelation_ to cancel any ongoing request that Grafana doesn't need.
+
+#### Before Grafana 7.2
+Before Grafana can cancel any data request, it has to identify that request. Grafana identifies a request using the property `requestId` [passed as options](https://github.com/grafana/grafana/blob/master/docs/sources/packages_api/runtime/backendsrvrequest.md) when you use [BackendSrv](https://grafana.com/docs/grafana/latest/packages_api/runtime/backendsrv).
+
+The cancellation logic is as follows:
+- When an ongoing request discovers that an additional request with the same `requestId` has started, then Grafana will cancel the ongoing request.
+- When an ongoing request discovers that the special "cancel all requests" `requestId` was sent, then Grafana will cancel the ongoing request.
+
+#### After Grafana 7.2
+Grafana 7.2 introduced an additional way of canceling requests using [RxJs](https://github.com/ReactiveX/rxjs). To support the new cancellation functionality, the data source needs to use the new `fetch` function in [BackendSrv](https://grafana.com/docs/grafana/latest/packages_api/runtime/backendsrv).
+
+Migrating the core data sources to the new `fetch` function [is an ongoing process that you can read about in this issue.](https://github.com/grafana/grafana/issues/27222)
+
+## Request queue
+Depending on how the web browser implements the protocol for HTTP 1.1, it will limit the number of parallel requests, lets call this limit _max_parallel_browser_request_. 
+
+Unless you have configured Grafana to use HTTP2, the browser limits parallel data requests according to the browser's implementation. For more information on how to enable HTTP2, refer to [Configuration](https://grafana.com/docs/grafana/latest/administration/configuration/#protocol).
+
+Because there is a _max_parallel_browser_request_ limit, if some of the requests take a long time, they will block later requests and make interacting with Grafana very slow.
+
+#### Before Grafana 7.2
+Not supported. 
+
+#### After Grafana 7.2
+Grafana uses a _request queue_ to process all incoming data requests in order while reserving a free "spot" for any requests to the Grafana API. 
+
+Since the first implementation of the request queue doesn't take into account what browser the user uses, the _request queue_ limit for parallel data source requests is hard-coded to 5.
+
+> **Note:** Grafana instances [configured with HTTP2 ](https://grafana.com/docs/grafana/latest/administration/configuration/#protocol) will have a hard coded limit of 1000.

-### Single Logout
+### IdP-initiated Single Sign-On (SSO)

-Single Logout feature allows user to log out from all applications associated with current IdP session established via SAML SSO. If `single_logout` option set to `true` and user logs out, Grafana requests IdP to terminate user session. Then IdP triggers logout process for all other applications which user logged in with the same IdP session (application should support single logout). And conversely, if another application connected to the same IdP initiates single logout, Grafana gets logout request from IdP and terminates user session.
+> Only available in Grafana v7.3+
+
+By default, Grafana allows only service provider (SP) initiated logins (when the user logs in with SAML via Grafana’s login page). If you want users to log in into Grafana directly from your identity provider (IdP), set the `allow_idp_initiated` configuration option to `true` and configure `relay_state` with the same value specified in the IdP configuration.
+
+IdP-initiated SSO has some security risks, so make sure you understand the risks before enabling this feature. When using IdP-initiated SSO, Grafana receives unsolicited SAML requests and can't verify that login flow was started by the user. This makes it hard to detect whether SAML message has been stolen or replaced. Because of this, IdP-initiated SSO is vulnerable to login cross-site request forgery (CSRF) and man in the middle (MITM) attacks. We do not recommend using IdP-initiated SSO and keeping it disabled whenever possible.

+
+SAML's single logout feature allows users to log out from all applications associated with the current IdP session established via SAML SSO. If the `single_logout` option is set to `true` and a user logs out, Grafana requests IdP to end the user session which in turn triggers logout from all other applications the user is logged into using the same IdP session (applications should support single logout). Conversely, if another application connected to the same IdP logs out using single logout, Grafana receives a logout request from IdP and ends the user session.

+# Grafana Mixin
+
+_This is a work in progress. We aim for it to become a good role model for alerts
+and dashboards eventually, but it is not quite there yet._
+
+The Grafana Mixin is a set of configurable, reusable, and extensible alerts and
+dashboards based on the metrics exported by Grafana. The mixin creates
+recording and alerting rules for Prometheus and suitable dashboard descriptions
+for Grafana.
+
+To use them, you need to have `mixtool` and `jsonnetfmt` installed. If you
+have a working Go development environment, it's easiest to run the following:
+
+```bash
+$ go get github.com/monitoring-mixins/mixtool/cmd/mixtool
+$ go get github.com/google/go-jsonnet/cmd/jsonnetfmt
+```
+
+You can then build the Prometheus rules files `alerts.yaml` and
+`rules.yaml` and a directory `dashboard_out` with the JSON dashboard files
+for Grafana:
+
+```bash
+$ make build
+```
+
+For more advanced uses of mixins, see
+https://github.com/monitoring-mixins/docs.
