+## activation example
+
+把一个 HTTP/gRPC 服务缩到零，第一个请求到达时再拉起来。请求被网关扣住等扩容，不是失败重试。
+
+和 [`samples/autoscaling`](../autoscaling)
的区别：那边是队列消费者，没有入向调用方，副本消失不会让谁的请求落空；这边是有人调用的服务，缩到零之后必须有东西在请求路径上接住第一个请求。
+
+### 链路
+
+```
+请求 -> dxgate 扣住请求
+ | 上报 pending 数（gRPC 流）
+ v
+ dubbod <-- KEDA 轮询 external scaler
+ |
+ v
+ ScaledObject -> Deployment 0 -> 1
+ |
+ v
+ EDS 下发新端点 -> dxgate 放行被扣住的请求
+```
+
+网关是唯一能做这件事的位置。出向是 proxyless 的，调用方进程内的 gRPC xDS client 直接拿 EDS
端点建连，端点为空时当场失败，请求路径上没有任何东西活得够久去触发扩容。而进到网关的请求已经在网关自己的 task 里，可以等。
+
+网关只负责等和上报，副本数始终由 KEDA 写。这条边界是有意的：网关重启不会把某个工作负载留在没人要求过的副本数上。
+
+### 前置
+
+```bash
+helm repo add kedacore https://kedacore.github.io/charts
+helm install keda kedacore/keda -n keda --create-namespace
+```
+
+需要一个 Gateway API 的 Gateway 把流量导到 `payment`。`dubbod` 会为它拉起 dxgate，并注入
`DXGATE_ACTIVATION_CONTROL_PLANE`。
+
+### 部署
+
+```bash
+kubectl create ns activation
+kubectl label ns activation dubbo-injection=enabled
+kubectl apply -f samples/activation/payment.yaml
+kubectl apply -f samples/activation/activation-policy.yaml
+kubectl apply -f samples/activation/scaledobject.yaml
+```
+
+### 验证
+
+等它自己缩到零（`cooldownPeriod: 300`，五分钟），或者直接改 `ScaledObject` 缩短：
+
+```bash
+kubectl -n activation get deploy payment -w
+# READY 0/0
+```
+
+然后打一个请求：
+
+```bash
+time curl -s http://$GATEWAY/payment/healthz
+```
+
+请求会挂住几秒——那是冷启动——然后正常返回，不是 503。同一时刻看网关：
+
+```bash
+kubectl -n dubbo-system exec deploy/dxgate -- \
+ curl -s localhost:15021/metrics | grep dxgate_activation_requests_held
+# dxgate_activation_requests_held 1
+```
+
+这个指标和 `dxgate_requests_in_flight`
是分开的，因为它们要区别对待：前者是在等扩容，后者是在等上游。混在一起会让一次冷启动看起来像网关变慢了。
+
+策略状态里能看到控制面这一侧是否就绪：
+
+```bash
+kubectl -n activation get serviceactivationpolicy payment -o
jsonpath='{.status.conditions}' | jq
+```
+
+四个 condition：`Accepted` 策略本身合法，`Eligible` 目标可被激活，`ScalerReady` KEDA
能拿到指标，`ActivatorReady` 有网关在上报。
+
+### 三个组件各自负责什么
+
+| 组件 | 负责 | 不负责 |
+| --- | --- | --- |
+| `ServiceActivationPolicy` | 声明哪个 Service 可以被激活、扣多久、扣多少 | 不写副本数 |
+| `ScaledObject` | 副本数的唯一归属 | 不知道请求被扣住这回事 |
+| dxgate | 扣住请求、上报 pending、端点出现后放行 | 不扩容任何东西 |
+
+少任何一个都不成立。只有策略没有 `ScaledObject`，请求会被扣满 `requestTimeout` 然后失败；只有 `ScaledObject`
没有策略，控制面不会为这个目标发布 scaler 指标，KEDA 拿不到 pending 数，服务永远停在零。
+
+### 哪些请求不能被扣住
+
+`protocols` 里只列了 `HTTP` 和
`GRPC_UNARY`。流式请求不在其中：一个流没法在目标起来之后重放，扣住它换到的冷启动，代价是这个流已经断了。长连接同理。
+
+对这类服务用 `minReplicaCount: 1`。
+
+### 第一个请求要等多久
+
+四段相加：
+
+1. KEDA 轮询间隔——样例里 `pollingInterval: 1`，最多 1s
+2. HPA 把副本从 0 改到 1
+3. Pod 调度 + 拉镜像 + 进程启动
+4. proxyless 冷启动：取证书、建 xDS 连接、等首次 CDS/EDS 收敛
+
+第 4 段是 sidecar 方案里由常驻 sidecar 摊销掉、而 proxyless 下每个副本都要重付的部分。上生产前量一下从 Pod
Running 到能收发流量的时间，再定 `requestTimeout`——它必须大于这个总和，否则请求总在服务刚要就绪时被判超时。
+
+`requestTimeout` 同时要小于调用方自己的超时。调用方已经放弃的请求，在网关这边多扣一会儿没有任何意义。
+
+### 扣住的请求占用什么
+
+每个被扣住的请求占一个 task 和一条连接。所以有两层上限：
+
+- `maxPendingRequests`（策略级，样例 100）——单个冷目标能占掉网关多少
+- `DXGATE_ACTIVATION_MAX_PENDING_REQUESTS`（网关级，默认 1024）——所有目标合计
+
+超过上限的请求直接失败，不进等待队列，也不会出现在上报里。这是有意的：让一个起不来的目标拖垮整个网关，比这些请求早点失败要糟得多。
+
+### 缩容时的排空
+
+和 `samples/autoscaling` 一样，被缩掉的 pod 走 dxplane 的两阶段排空：先 5s 只失败 readiness 让
EndpointSlice 摘掉，再关监听等在途连接最多 25s。`terminationGracePeriodSeconds`
必须大于两者之和，`payment.yaml` 里是 40s。
+
+`dxplane_connections_force_closed_total` 非零说明 25s 不够，调
`DUBBO_GRPC_INBOUND_TERMINATION_DRAIN_DURATION`。
+
+### 为什么 scaler 地址是 headless 的
+
+```yaml
+scalerAddress: dubbod-activation-replicas.dubbo-system.svc.cluster.local:26030
+```
+
+不是 `dubbod-activation`。KEDA 查询会落到某一个副本上，而网关上报也只会到某一个副本——如果两边落到不同副本，KEDA 看到的
pending 永远是 0。所以网关向 headless 名解析出的**每一个**地址都上报一份，这样无论 KEDA 问到谁都能拿到数。
+
+同理，网关必须注入 `POD_NAME`：控制面按 reporter 身份聚合，两个网关副本共用一个身份会互相覆盖。这个变量由
`kube-gateway.yaml` 自动注入。
+
+### 东西向还不行
+
+这个样例是南北向的：请求从网关进来。
+
+服务之间的调用（东西向）目前不能缩到零。调用方是 proxyless 的，直接读 EDS
建连，中间没有网关。`dubbod/discovery/pkg/xds` 还不感知激活状态，缩到零时下发的是空端点列表，调用方直接失败。
+
+所以只被其他服务调用、不经过网关的服务，仍然用 `minReplicaCount: 1`。

出向是 proxyless 的：调用方进程内的 gRPC xDS client 直接拿 EDS 端点建连。副本归零时
dubbod 下发一个空的 CLA（`dubbod/discovery/pkg/xds/endpoints/endpoint_builder.go`），
-调用方立即失败。请求路径上没有任何组件能扣住这个请求去触发扩容 —— sidecar 网格里由
-sidecar 或 activator 承担的那个位置，在这里是空的。
+调用方立即失败。服务之间的调用路径上没有任何组件能扣住这个请求去触发扩容 —— sidecar
+网格里由 sidecar 承担的那个位置，在这里是空的。
-所以对被调用的服务用 `minReplicaCount: 1`。等 dxgate 的 Activator 模式落地后，
-北南向的 Unary 请求才能按需激活。
+南北向不同：请求进了网关就已经在网关自己的 task 里，可以等。这就是
+[`samples/activation`](../activation) 做的事。
+
+所以判断标准是**这个服务的调用方从哪来**，而不是它说什么协议。只被其他服务调用的，
