To build a k6 binary with this extension, first ensure you have the prerequisites:
- Go toolchain
- Git
Then:
- Clone
xk6:
git clone https://github.com/k6io/xk6.git
cd xk6- Build the binary:
CGO_ENABLED=1 go run ./cmd/xk6/main.go build master \
--with github.com/dgzlopes/xk6-kv// script.js
import kv from 'k6/x/kv';
export const options = {
scenarios: {
generator: {
exec: 'generator',
executor: 'per-vu-iterations',
vus: 5,
},
results: {
exec: 'results',
executor: 'per-vu-iterations',
startTime: '5s',
vus: 1,
},
},
};
const client = new kv.Client();
export function generator() {
client.set(`hello_${__VU}`, 'world');
}
export function results() {
console.log(client.get("hello_1"));
var r = client.viewPrefix("hello");
for (var key in r) {
console.log(key,r[key])
}
}Result output:
