Can be better adapted to multiple platforms (k8s, vm); +apisix-control-plane is an implementation of providing a control plane for DPs (Data Plane) like Apache APISIX or other gateways. with a `yaml` configuration capability, We can use `yaml` to define the behavior of any DP. + +## Why do we need to implement a control-plane + +For now, we have a default implementation for Apache APISIX. + +As we knows, Apache APISIX is a high-performance gateway. When using APISIX we need to inform apisix of some proxy rules, and distribute these rules to apisix modules. We can call it contol-plane, similar to pilot in istio. Of course, the distribution configuration is only the most basic function of the control plane. + +We know that apisix already has Admin API, so why do we need to implement a control-plane? + +First of all, Apache APISIX Admin API is a way to define a single object, such as a single object such as route / service / upstream / consumer, although it is also possible to completely define a route through a huge route object, and the upstream object is embedded in the route , But any minor changes will trigger the reconstruction of the route. Rebuilding the route is definitely not a good idea and reduce performance. + +In fact, leaving aside the Admin API, what we need is a description method that can completely define the rules while maintaining the legibility of the Admin API. Therefore, we have [discussion here](https://github.com/apache/apisix-control-plane/blob/master/doc/yaml_struct.md), and we have implemented a version of the basic functions according to this data structure , I hope everyone puts forward their views. We can also submit a PR to modify this [document](doc/yaml_struct.md). + +Secondly, Apache APISIX Admin API uses id associations to strongly bind objects to express the relationship between objects. For example, the route object uses `service_id` and `upstream_id` to bind the relationship with service and upstream respectively. + +This kind of representation, like the well-known relational database, is easier to understand and reduces redundant configurations. But it also brings some other problems. For example, rely on verification. When we want to bind an `upstream_id` to a route, we must first create the upstream, and then bind the generated `upstream_id` to the route. This process corresponds to two Admin APIs, and there is no transaction management. + +We hope that the emergence of control-plane can solve the above two problems. +1. Use yaml declarative definition method to define complete rules. +2. Block DP implementation details, describe object relationships in a unified way. + +Of course, with control-plane we can do more. + +For example, based on gitops configuration version management, it is also more convenient to use yaml to define apisix in k8s. + +Realize the prototype of cross-cluster synchronization configuration through the control panel. In the future, we can also enrich the functions of the control plane and simplify management under the cluster mode of multi-platform hybrid deployment (k8s/vm). We can also shield specific implementations of APISIX and provide configuration functions for more types of gateways. + +## Feature support + +1. Support the declarative definition of yaml. +2. Use the memory database to synchronize the gateway status. +3. Diff capabilities based on memory objects. +4. Sync / update the apisix configuration. +5. Support incremental synchronization. +6. Support transaction processing. + Review comment: What's the plan for other DPs? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
