+# Command line tools for interacting with Jetstream protocol
+
+## Usage
+
+* To build, invoke `mvn install`.
+* To list available commands `./tools/target/app/run.sh`.
+* To get available options for a command `./tools/target/app/run.sh  --help`.
+
+## Common Options
+
+* `--table-name` the full table name to send RPCs to. Currently this
+  defaults to a table in the test environment.
+* `--app-profile-id` the app profile id to use. Defaults to `default`
+* `--mode` configures the underlying transport. Can be one of
+  * `CloudPath` - Uses traditional CFE path
+  * `CloudPathTd` - Use CFE, but uses TrafficDirector to route to the CFE
+  * `DirectPath` - Uses TrafficDirector + DirectPath
+  * `RawDirectPath` - Uses DirectPath using raw ip as obtain from 
+    [Borg Task Manager Summary](https://playbooks.corp.google.com/cloud-bigtable/procedures/DirectPathEndpointSetup.md?cl=head#:~:text=The%20Borg%20Task%20Manager%20Summary)
+  * `--endpoint` - The endpoint of the target.
+    * For CloudPath, this should include both the hostname and port. ie.
+    `test-bigtable.sandbox.googleapis.com:443`.
+    * For `CloudPathTd`, it should be just be the c2p target without a port. ie
+    `test-bigtable.sandbox.googleapis.com`.
+    * For `RawDirectPath`, it should be IP:port from the Borg summary page.
+    * For `DirectPath`, it should be just be the c2p target without a port ie.
+    `test-bigtable.sandbox.googleapis.com`.
+
+## Commands
+
+* `generate-load` - generates steady traffic using Jetstream. This will use
+  the same row key for all requests. This is meant to test the transport.
+  The load shape can be configured via the cli options
+* `generate-unary-load` - similar to `generate-load`, but uses the classic
+  unary protocol. Mainly used for comparison and antagonistic traffic.
+* `readrow` - reads a single row using Jetstream.
+* `mutaterow` - mutates a single row using Jetstream.
+* `ycsb` - wraps the ycsb benchmark. It exposes the ycsb configuration using
+  normal java cli options. Latency histograms will be stored by default in `results/`.
+* `ycsb-summarize` - Summarizes a histogram timeseries file. 
+
+## GKE
+
+* A docker image of the tools lives at gcr.io/google.com/cloud-bigtable-dev/jetstream-tools
+* Prerequisite: install kubectl: https://cloud.google.com/kubernetes-engine/docs/how-to/cluster-access-for-kubectl#install_kubectl
+* Setup
+  ```shell
+    # Download credentials
+    gcloud auth configure-docker  us-docker.pkg.dev
+    gcloud container clusters get-credentials jetstream-gke \
+      --region europe-west1 --project google.com:cloud-bigtable-dev
+    # Install jq
+    brew install jq
+  ```
+* A deployment in gke was created with:
+  ```shell
+  mvn clean install -P docker-publish \
+      && kubectl apply -f tools/gke/ycsb.yaml
+  ```
+* To update the image:
+  ```shell
+    # Build, upload docker image and update the deployment
+    mvn clean install -P docker-publish \
+      && kubectl set image deployment/jetstream-tools-ycsb jetstream-tools-ycsb=$(cat tools/target/jib-image.json | jq -r '.image')
+  ``` 
+* To change parameters:
+  ```shell
+  kubectl edit deployment/jetstream-tools-ycsb
+  # or to reset to the default config
+  kubectl apply -f tools/gke/ycsb.yaml 
+  ```
+
+* To summarise YCSB results
+  ```shell
+  kubectl exec $POD_NAME -- /bin/sh -c "java -cp /app/resources:/app/classes:/app/libs/* com.google.cloud.bigtable.jetstream.tools.Main ycsb-summarize"
+  ```
+
+## Maintenance
+
+### ycsb
+
+Unfortunately ycsb doesn't publish artifacts to maven central, so the jars
+are vendored as a local maven repository under tools/vendored-libs. To
+update the jars:
+
+```sh
+git clone https://github.com/brianfrankcooper/YCSB.git /tmp/YCSB
+git -C /tmp/YCSB reset --hard 1e62880552fc95fa4b012846c0f3887420e676a8
+YCSB_VERSION="0.18.0-SNAPSHOT"
+
+# Build YCSB parts we care about
+mvn -f /tmp/YCSB/pom.xml \
+  clean package -DskipTests -am -pl core,googlebigtable2
+
+# copy the vendored jars
+cp /tmp/YCSB/core/target/core-${YCSB_VERSION}.jar \
+  /tmp/YCSB/googlebigtable2/target/googlebigtable2-binding-${YCSB_VERSION}.jar \
+
+  $PWD/../tools/vendored-libs
+```
+
+
+
+Creating a new GKE cluster
+```shell
+gcloud container --project "google.com:cloud-bigtable-dev" clusters create "jetstream-gke" \
+  --region "europe-west1" --tier "standard" \
+  --machine-type "e2-standard-32" --image-type "COS_CONTAINERD" \

+  --num-nodes "1" \
+  --network "projects/google.com:cloud-bigtable-dev/global/networks/igor-default" \

+  --enable-autoscaling --min-nodes "0" --max-nodes "5" --location-policy "ANY"

+ *
+ * 
    
+ *   
  • CloudPath - connect via a GFE
+ *   
  • DirectPath - connect via a c2p DirectPath target
+ *   
  • CloudPathTD - use traffic director, but request an endpoint via CFE
+ *   
  • RawDirectPath - connect DirectPath by specifying an AFE ip/port
+ *

+ * 
In addition, the endpoint & port can be overridden for a mode using the {@code --endpoint}
+ * option. The port is only relevant for DirectPath and CloudPath modes and defaults to 443.

By default the target will be DirectPath using the {@code
