Intro

Performance Enhanced

In this version, we have restructured the cloud function runtime, enhancing the execution performance of cloud functions by over 400%, HTTP request QPS by more than 300% (with CPU usage savings of over 200% under the same concurrency), and Websocket long connection performance by over 500%.

New logger implementent of runtime

Additionally, we have restructured the function log implementation, now directly using Runtime Pod log streams, which supports real-time log viewing and beautification of log formats.

New billing & monitoring implement of application

We have also rewritten application resource monitoring and metered billing, enabling laf in the sealos user namespace to support resource monitoring and metered billing functions.

What's Changed

Full Changelog: v1.0.0-beta.12...v1.0.0-beta.13

Migration Guides

Update laf-server & laf-web images:

# upgrade laf SERVER
kubectl set image deployments/laf-server -n laf-system \
	laf-server=docker.io/lafyun/laf-server:1.0.0-beta.13

# upgrade laf WEB
kubectl set image deployments/laf-web -n laf-system \
	laf-web=docker.io/lafyun/laf-web:1.0.0-beta.13

Update sys_db.Runtime to upgrade runtime images in MongoDb

use sys_db
// runtime version
const version = "1.0.0-beta.13"

const main_image = `docker.io/lafyun/runtime-node:${version}`
const init_image = `docker.io/lafyun/runtime-node:${version}`

db.Runtime.updateOne({ latest: true }, {
  $set: {
    version: version,
    image: {
      main: main_image,
      init: init_image
    }
  }
})

db.Runtime.find().pretty()

Restart all Running applications by update sys_db.Application in MongoDb

use sys_db
db.Application.updateMany({ state: 'Running' }, {
    $set: {
        state: 'Restarting'
    }
})

Enabling Resource Monitoring

This version of Laf uses a specialized runtime exporter for runtime resource metrics collection, so you will need to install the runtime exporter into the cluster to enable resource monitoring
