Delta Lake 是一個開源項目，可以在現有存儲系統（例如 ADLS 和 HDFS）之上構建 Lakehouse 架構，並與 Apache Spark API 完全兼容。 Delta Lake 為您的數據湖帶來 ACID 規範。它提供數據快照，使開發人員能夠查找和恢復到早期版本的數據以進行審計、數據恢復或實驗。實時數據提取、批量數據整合和交互式查詢都能夠開箱即用。Mike Chan 將為我們介紹 Delta Lake 的好處和最近的使用體驗，讓大家能充份發揮不同數據的潛能。
List of Events
Here is a list of event, includes speaker session and other intermediate slots (e.g. lunch):
In this session, I will briefly introduce about ChatOps concept and demo a real scenario of triggering a playbook with a chatbot.
And I will show how to set up a chat server and deal with the chats tasks in an intranet environment.
Quarkus is an open sourced, Kubernetes-native Java framework made for Java virtual machines (JVMs) and GraalVM native compilation. Quarkus is optimized specifically for containers. It greatly minimizes application startup time and memory use, and it provides live coding so that developers can immediately check the effect of code changes in the blink of an eye. With these features, they enable Quarkus to become an effective platform for serverless, cloud and Kubernetes environments. Join this session to have a first look into Quarkus.
Drug labels in Hong Kong are mainly presented in words. Elderly or ethnic minorities might find it difficult to fully understand them. The carers need to spend extra time explaining and handwriting remarks to ensure medication adherence.
We took reference from other places’ prescription labels and designed a set of unified Drug Icons, which can be stuck on the medicine packages to visualise the prescription notes for easier understanding.
This session will show you the features from an Ultimate acceleration InnoDB sub-engine - Heatwave, and how it works with Grafana aggregates hundreds millions of rows in seconds to create a real time dashboard, this session also show you how to show the details of how MySQL handles these queries on Grafana
This presentation will provide an overview of The Academy Software Foundation (https://www.aswf.io/) and their impacts on the visual effects and animation industry around the globe. Moreover, there are local software developers who contributed to the Hong Kong's original digital Ink-painting and animation creations. The speaker aims to reveal a couples of CGI Ink-painting and animations made from these Hong Kong software tools.
We know the whole world is embracing Open Source. This talk wants to share what is COSS (Commercial Open Source Software) model? How COSS model benefits both the company and community? Why a company choose COSS model, and finally, is it suitable for every enterprise? Let's discover!
MySQL High Availability has been around our discussion over years. It is redundancy and allowing service to be always online. Kubernetes is one of the hot topics these days. During the talk, we will share how we can deploy MySQL in Kubernetes. As standalone pod or deployment or as InnoDB Cluster with Kubernetes. This is the sneak preview of MySQL Operator for Kubernetes. Come and join us to share your idea.
It’s hard to arrange community events after COVID-19 pandemic. But there is still a strong need to gather, to share, and to learn from other developers. In this talk, I will share our experiences of how to build the Koltin community online in Taiwan from 2019 to present. The topics will be about how we arrange study jams, how we run workshops, how we build a team to attend competitions, how we connect companies to become a league, and the most important, how we grow the community and the lesson learned.
This will be a short talk mentioning the updates of the Open ArozOS project I shared in last year's conference. The share will include the story of transitioning a project from PHP based to Golang based, a newly open sourced ESP8266 powered IoT control system for prototyping and some new development concepts that involving PWA technology using ArozOS as the backend. If there are excess time, I might also discuss the design advantage when developing complex system using Web Desktop UI instead of the traditional Dashboard UI.
