It was an all-day community-run event held on August 17th. Admission was free thanks to our generous host, the Alibaba Group. This was the second HBaseConAsia conference. The first was hosted by Huawei in Shenzhen, in 2017.</span><img src="https://lh3.googleusercontent.com/XGD2gIQ_upgfzr5lCw4XxreNJ1xNtJWB5F1gc7uxs-Kxx1LbNsDFzafjvTxjJ18pVdALfjxh7apss-XE9HRhxEoY6SWhFLeaNtKzxOYR0TepmPFsRe3JstSmWP85TNmXx1k2rKmd" style="transform: rotate(0rad);" width="414" height="311" align="right" /></p><br />

Below are links that point into slideshare where you’ll find slides and video. There were three tracks -- internals, ops, and ecosystem -- of heavy-duty hbasing.</span></p><br />
