Scale Out a TiFlash Node

This Go code sample shows you how to scale out a TiFlash node for your cluster and view the scale-out progress.

Prerequisites

Before you start, make sure you have created the API key, configured environment variables, and installed the required Go version.

For details, refer to Prerequisites for Go.

Run the sample

1. Clone the repository:

   git clone https://github.com/tidbcloud/tidbcloud-api-samples.git
   

2. Change to the scale_out_tiflash directory and run make to compile the code into an executable.

   cd go/scale_out_tiflash/
   make default # GO11MODULE=on go build -o bin/scale_out_tiflash .

   After the compilation, the directory structure is similar to this:

   .
   ├── bin  # the binary is generated under this directory
   │   └── scale_out_tiflash
   ├── client.go  # http client
   ├── main.go  # entrypoint of this program
   ├── Makefile
   ├── README.md
   └── types.go  # all the structures we need for this demo

3. Execute the program.

   # export TIDBCLOUD_PUBLIC_KEY="<your public key>"
   # export TIDBCLOUD_PRIVATE_KEY="<your private key>"
   # export DEDICATED_PROJECT_ID="<your dedicated project id>"
   # export DEDICATED_CLUSTER_ID="<your dedicated cluster id>"
   
   ./bin/scale_out_tiflash
