Panel: Open Data Architecture

The Open Data Architecture panel closes Subsurface LIVE Summer 2021 with a lively discussion about the state of the cloud data lake with some of the most influential creators and contributors to key open source data lake software. Moderator Gartner analyst Sanjeev Mohan opens the panel with highlights of recent cloud data lake industry trends. Then he asks the open source panelists questions such as:

  1. Why data lakes have not, until now, succeeded in having the fast turnaround of data that was expected;
  2. What missteps have there been along the way and what lessons have we learned from them;
  3. What each contributors journey has been, and why they have succeeded.
