Using a dedicated on-disk file format, that is, a custom index has much advantages, optimizations opportunities. I thought using an existing OKVS would be an advantage from a time to market perspective, but it is not the case :)

I think most off-the-shelf stuff is a dead end. You see fairly frequent attempts using both KVS:es and like elasticsearch or similar. Like you can get it to work, but it just doesn't scale.
