🗓️ Agenda
Speaker:
- Marija Selaković - Developer Advocate Crate.io
- Rafaela Sant'ana - Developer Advocate Intern Crate.io
In his introductory talk, Christian Lutz, founder of Crate.io, will tell you about our journey with CrateDB. He will share the reason and motivation for launching a new database system and why we started CrateDB as an open-source project. Be ready to hear about our key milestones, latest developments, and vision for the future.
Speaker: Christian Lutz, Founder and Director of the Board, Crate.io
In this talk, Candelario A. Gutierrez from the University of Alberta, will talk about how we leverage CrateDB into their platform for analyzing social-platform data. This work is reported in the paper “Analyzing and visualizing Twitter conversations”. He will provide more detailed information on the technical aspects of their platform, of interest to software developers who deal with similar data and are interested in exploring CrateDB.
Speaker: Candelario A. Gutierrez, M.Sc. in Computing Science
Bitmovin produces billions of rows of data and stores it in CrateDB. In this talk, Daniel will explain how Bitmovin uses CrateDB to monitor the most significant live video events and especially which features they are using to address their monitoring and scalability challenges. Learn also about their typical queries and how the support from Crate.io helps them in their day-to-day.
Speaker: Daniel Hölbling-Inzko Director of Engineering – Analytics, Bitmovin
Learn how to get started using Apache Airflow and CrateDB in this introductory talk by Tamara Fingerlin, Developer Advocate at Astronomer. Tamara will walk you through setting up Airflow locally, connecting your Airflow instance to CrateDB, and using the Postgres provider to orchestrate your data pipelines. Combining these two open-source technologies will set you up to get the most value out of your data.
Speaker: Tamara Janina Fingerlin, Developer Advocate, Astronomer
In this talk by our engineers, learn more about CrateDB Cloud in a demo environment. We will demonstrate how to start and scale the new cluster, how to implement logical replication, run data ingestion, and understand the real costs behind CrateDB Cloud. Guess who will be the next CrateDB Cloud expert in the room 😉.
Speakers:
- Roman Meingassner, Senior Product Manager, Crate.io
- Romanas Sonkinas, Lead Engineer of CrateDB Cloud, Crate.io
Datastores promise easy scaling of your cluster to handle your data needs, providing top performance, but it (almost) never works as promised with out-of-the-box configuration. So, how can you scale efficiently with CrateDB and achieve performant queries? You will learn how sharding & partitioning choices, along with correct data modeling can get you there. Also, discover how to monitor your cluster to avoid unpleasant surprises, as Marios will share his best practices to keep your cluster healthy at all times! Finally, you'll learn about the key factors which will allow you to deploy CrateDB to the cloud and achieve the desired performance.
Speaker: Marios Trivyzas, Senior Software Engineer, Crate.io
