Will the conference be an in-person event or a virtual gathering?

Berlin Buzzwords usually is an onsite event, where people meet and get together to exchange news and trends in the Big Data open source world. 2020 was the first time we took the event to a virtual space to keep everybody safe and healthy at home. For 2021, it is of yet uncertain what we will be able to offer. At the moment, we can only say for sure that there will be an online event. We will do everything we can to make an onsite-edition possible again. In that case, you will be able to upgrade your ticket from online to onsite.
