| 21 | * PHP client for QPS testing works as follows: |
| 22 | * 1. Gets initiated by a call from a proxy that implements the worker service. The |
| 23 | * argument to this client is the proxy connection information |
| 24 | * 2. Initiate an RPC to the proxy to get ClientConfig |
| 25 | * 3. Initiate a client-side telemetry RPC to the proxy |
| 26 | * 4. Parse the client config, which includes server target information and then start |
| 27 | * a unary or streaming test as appropriate. |
| 28 | * 5. After each completed RPC, send its timing to the proxy. The proxy does all histogramming |
| 29 | * 6. Proxy will respond on the timing channel when it's time to complete. Our |
| 30 | * next timing write will fail and we know that it's time to stop |
| 31 | * The above complex dance is since threading and async are not idiomatic and we |
| 32 | * shouldn't ever be waiting to read a mark |
| 33 | * |
| 34 | * This test only supports a single channel since threading/async is not idiomatic |
| 35 | * This test supports unary or streaming ping-pongs, as well as open-loop |
