+# Stress Test framework for gRPC
+
+(Sree Kuchibhotla - sreek@)
+
+> Status: This is implemented. More details at [README.md](https://github.com/grpc/grpc/blob/master/tools/run_tests/stress_test/README.md)
+
+
+**I. GOALS**
+
+1) Build a stress test suite for gRPC:
+
+* Build a stress test suite that can Identify bugs by testing the system (gRPC server/client) under extreme conditions:
+  * High load
+  * High concurrency
+  * Limited resources 
+  * Intermittent failures
+* Should be integrated with Jenkins CI
+
+2) Make it generic enough (i.e build a generic test framework) that can be used for:
+
+* Executing M instances of a client against N instances of a server with an arbitrarily defined connection matrix
+   * Execute heterogenous test configurations - for example: Java stress test clients against C++ servers or Node clients against Python servers or TSAN C++ clients vs ASAN C++ Servers etc.
+   * Easy and Flexible enough that Devs can use it to recreate complex test scenarios
+
+The implementation effort is divided into two parts:
+
+* Building a "Stress Test Framework" to run the stress test suites- More details in **Section II** (The idea is that the Stress Test framework is generic enough that it would be easier to modify it to run other suites like interop-tests or custom test scenarios)
+* Building a 'Stress test suite' - More details in **section III**
+
+**Terminology:**
+
+GCE - Google compute engine
+GKE - Google Container engine
+Kubernetes - Google's open source service scheduler / orchestrator.
+
+**Note:** The terms GKE and Kubernetes are used interchangeably in this document
+
+# II. STRESS TEST FRAMEWORK
+
+(The details of each step are explained below))
+![image](images/stress_test_framework.png)
+**Figure 1**
+
+### Step 1 Read the test config, generate base docker images
+
+**_Test Config:_** The test configuration contains the following information:
+
+* _GKE info:_ GKE project and cluster info
+* _Docker images:_ Instructions to build docker images
+* _Client templates:_ One or more client templates each containing the following information:
+    * Which docker image to use
+    * Path to the client program to launch (within the docker image)
+    * Parameters to the client program
+* _Server templates:_ Similar to Client templates - except that these are for servers
+* Test matrix containing the following:
+    * _Server groups:_ One or more groups of servers containing the following info for each group
+        * Which server template to use
+        * How many instances to launch
+    * _Client groups:_ One or more groups of clients containing the following (for each group):
+        * Which client template to use
+        * How many instances to launch
+        * Which server group to talk to (all clients in this group will talk to all servers in the server group)
+
+The first step is to read the test config and build the docker images
+
+**_Stress server docker image:_** The following are the main files in the server docker images
+
+* _Interop_server:_ The server program
+* `run_server.py`: This is a python script which is the entry point of the docker image (i.e this is the script that is called when the docker image is run in GKE).  This script launches the interop server and also updates the status in BigQuery.  If the interop_server fails for whatever reason, the script launch_server.py logs that status in BigQuery
+
+**_Stress client docker image:_**
+
+* Stress client: The stress test client.  In addition to talking to the interop_server, the stress client also exports metrics (which can be queried by the metrics_client described below)
+* Metrics client: Metrics client connects to the stress_client to get the current qps metrics.
+* `run_client.py`: This is a python script which is the entry point of the docker image (i.e this is the script that is called when the docker image is run in GKE). This script launches the stress client and also updates the status in BigQuery.  The script then periodically launches metrics client to query the qps from the stress client and then uploads the qps to BigQuery.
+
+### Step 2) Upload the docker images to GKE
+The docker images are uploaded to the GKE registry
+
+### Step 3) Launch the tests in GKE
+The test driver reads the test matrix (described in step 1) and creates the necessary server and client pods in GKE.
+
+### Step 4) Tests are run in GKE
+GKE starts running the tests by calling the entry points in *each* docker image (i.e `run_server.py` or `run_client.py` depending on whcih docker image it is)
+
+### Step 5) Upload the status to GKE and Monitor the status in GKE
+* 5.1 The tests periodically update their status in BigQuery
+* 5.2 The test driver periodically checks the status in Bigquery to see if any tests failed.  If any tests failed, the driver immediately stops the tests.  If not, the driver continues to run the tests for a configurable amount of time.
+
+### Step 6) Create a summary report
+The test driver creates a final summary report containing details about any test failures and information about how to connect the failed pods in GKE for debugging.

-initial metadata for a request. It does this by providing a grpc_subchannel

+/** \file Tracks resource usage against a pool.
+
+    The current implementation tracks only memory usage, but in the future
+    this may be extended to (for example) threads and file descriptors.
+
+    A grpc_resource_quota represents the pooled resources, and
+    grpc_resource_user instances attach to the quota and consume those
+    resources. They also offer a vector for reclamation: if we become
+    resource constrained, grpc_resource_user instances are asked (in turn) to
+    free up whatever they can so that the system as a whole can make progress.
+
+    There are three kinds of reclamation that take place, in order of increasing
+    invasiveness:
+    - an internal reclamation, where cached resource at the resource user level
+      is returned to the quota
+    - a benign reclamation phase, whereby resources that are in use but are not
+      helping anything make progress are reclaimed
+    - a destructive reclamation, whereby resources that are helping something
+      make progress may be enacted so that at least one part of the system can
+      complete.
+
+    Only one reclamation will be outstanding for a given quota at a given time.
+    On each reclamation attempt, the kinds of reclamation are tried in order of
+    increasing invasiveness, stopping at the first one that succeeds. Thus, on a
+    given reclamation attempt, if internal and benign reclamation both fail, it
+    will wind up doing a destructive reclamation. However, the next reclamation
+    attempt may then be able to get what it needs via internal or benign
+    reclamation, due to resources that may have been freed up by the destructive
+    reclamation in the previous attempt.
+
+    Future work will be to expose the current resource pressure so that back
+    pressure can be applied to avoid reclamation phases starting.
+
+    Resource users own references to resource quotas, and resource quotas
+    maintain lists of users (which users arrange to leave before they are
+    destroyed) */
