Data Lake Icon: Visual Reference

Image
Data Lake Icon If you were looking for some data lake icons or data lake logos, our creative team created a few for Openbridge. Data Lake Icons In terms of consistent visual representations of a data lake, we were not happy with what was available. Rather than create a unique AWS data lake icon or an Azure data lake icon, we wanted these to apply generally across all platforms. As a result, we created a set of icons that reflect a data lake conceptually. We included a modified icon that reflects our data lake formation process: data lake logo Data Lake Icons Use Cases The following are some examples of how the icons are used Openbridge : Using the icon in animation in a data lake introduction visual block Using the icon in the “ what is a data lake ” page header Using the icon in the “ why data lake ?” graphic Using the task icon to describe formation & architecting data lakes Looking for data lake providers or a data lake roadmap?

Image
PrestoDB Last year we posted an introduction article on Presto . So what is new in the Presto world since then? A ton! PrestoDB moves to the Linux Foundation In September 2019, the official PrestoDB Foundation was started by Facebook, Uber, Twitter, and Alibaba. A formal, official foundation is what was needed for the Presto ecosystem to prosper. The formation and transition to a formal foundation under the Linux Foundation’s auspices was a significant first step to deal with confusion in the community. Kudos to Facebook, Uber, Twitter, and others in making this a reality. Having open, shared, and community-driven organization is critical to future success Presto. You can read more about these principles and roadmaps  here . Revisiting PrestoDB vs. PrestoSQL Why is a formal, independent foundation necessary? Presto Foundation established a set of much-needed guiding principles for the community. In the post last year, we highlighted some confusion about the two principle Pr
