YottaDB Presentations
We're always reaching out to our community with presentations at conferences and user group meetings. Here are some recent presentations. If you would like us to present at your event, please contact us.
YottaDB at FOSDEM 2024
At the FOSDEM 2024 Declarative and Minimalistic Computing devroom, K.S. Bhaskar gave a talk, The Old Remains New on how the M hierarchical key-value technology has evolved to stay relevant.
YottaDB at All Things Open 2023
YottaDB was a Bronze Sponsor of All Things Open 2023. We had over 100 people visit our table, where we had a simulated edge-to-cloud IoT stack:
- Simulating the edge, we had a Raspberry Pi with
- two analog gas sensors on an Arduino measuring CO2, alcohol, CO, etc.;
- digital motion and temperature sensors; and
- an LED that the operating software would turn on when the motion sensor detected motion.
- The database from the simulated edge was replicated in real time to another Raspberry Pi, simulating the cloud. On the cloud, the data was mapped to SQL tables with Octo, from where the data could be accessed using Excel, LibreOffice and the YottaDB GUI.
We also demonstrated a Docker container comparing YottaDB and Redis. The screenshot is from that container. You can decide for yourself whether YottaDB is the fastest key-value database on the planet.
Bhaskar gave a talk on Fun with Forensics: Using SQL to Find Needles in Haystacks.
YottaDB at 41st VistA Community Meeting
The 41st VistA Community Meeting was the fourth all-virtual VistA Community meeting, and also Bhaskar’s 41st VistA Community Meeting. Sam was the most active participant in the conference program.
Sam Habiel gave three talks and participated in a panel discussion on AI for VistA:
- YottaDB GUI Update
- SQL Access to VistA Update
- VistA Web Resources
- Panel discussion on AI for VistA with Greg Kreis and Matt King
K.S. Bhaskar gave two talks:
- YottaDB Update
- Fun With Forensics – Troubleshooting, analytics and forensics with journal files and the syslog

YottaDB at All Things Open 2022
All Things Open 2022 was the tenth year of the open source technology conference. YottaDB returned with an in-person booth to ATO after three years.
We demonstrated YottaDB in a simulated Internet of Things application. We had temperature, motion, carbon dioxide and volatile organic compound sensors connected to a Raspberry Pi. The motion sensor was connected to a red LED. Data was recorded locally, and replicated in real-time to another Raspberry Pi, the one with a small touch-sensitive display at the front of the table. That display showed the YottaDB GUI (under development, and current field test grade software), including the key-value nodes of the data. That Raspberry Pi also ran Octo, and on a laptop we demonstrated a real-time Excel graph of the data, which it accessed using ODBC.
October 30 – November 2, 2022
YottaDB at 40th VistA Community Meeting
The 40th VistA Community Meeting was the third all-virtual VistA Community meeting, and also Bhaskar’s 40th VistA Community Meeting. He gave a YottaDB update. Sam Habiel presented Octo, VistA Docker Images, the YottaDB Web Server, and the YottaDB Management GUI under development.

YottaDB at 39th VistA Community Meeting
The 39th VistA Community Meeting was the second all-virtual VistA Community meeting, and also Bhaskar’s 39th VistA Community Meeting. He gave a YottaDB update and a presentation on AIM. Sam Habiel presented Octo and the YottaDB Management GUI under development.
October 22-24, 2021
YottaDB at 38th VistA Community Meeting
The 38th VistA Community Meeting was the first all-virtual VistA Community Meeting, and also also K.S. Bhaskar’s 38th VistA Community Meeting! He gave a YottaDB update, a presentation on Octo, and also made a proposal for moving VistA forward using Go.
August 28-30, 2020
YottaDB at FOSDEM 2020
K.S. Bhaskar & Stefano Lalli
YottaDB was at FOSDEM 2020 in Brussels. We would like to thank Stefano Lalli, developer of YottaDB Studio and a member of the YottaDB user community for helping out. FOSDEM was so intense that without him, it would have been impossible for K.S. Bhaskar to manage the YottaDB table!
K.S. Bhaskar gave a talk on Dragons of CGO .
A Way for VistA to Go Forward
At the 2019 OSEHRA Open Source Summit, K.S. Bhaskar talked about the YottaDB approach to VistA, the language agnostic database and the YottaDB Go Wrapper.
