This is a video that was created for SingleStore to teach about sharding and shard keys in SingleStore DB. It includes a slide deck that I created in PowerPoint with animations that visibly demonstrate the concepts. I also did the voice over.
This is a video that demonstrates the creation of shard keys in SingleStore and shows the results of creating various shard keys. It is a recording of my screen with voiceovers that I also did. It also includes visual effects done in Adobe Premier.
This is the powerpoint presentation that is included in the Conceptual video above. There is no audio, the video simply goes through all of the slides and animations in a faster manner than they normally would.
You can also download the PowerPoint presentation. Be sure to view it in presentation mode so you can see the animations.
