Quantization: The Important Bits

Hey everyone, in this episode I speak to Ben Trent, one of Elastics Sr Principal engineers, about Quantization. We recorded this episode a while ago and since then, launched our latest quantization feature, BBQ. So this will be a good primer in prep for leveraging that feature which we touch on briefly at the end. I plan to record another episode covering BBQ specifically so hopefully you stay curious!
