For those interested, you can build a system like this that tracks sub-second GPS information, and easily scale to 100M+ writes for $10/day with 1KB payload (compare to the 62bytes in the article). Here is a demo we threw together of it working in real life: https://youtu.be/7ALHtbC9aOM https://youtu.be/7ALHtbC9aOM Here is a prototype of saving 100M+ writes for $10/day: https://www.youtube.com/watch?v=x_WqBuEA7s8 https://www.youtube.com/watch?v=x_WqBuEA7s8 Our sync system: https://github.com/amark/gun https://github.com/amark/gun And since we are on the topic, I highly recommend this engineering blog post by Discord on how they scaled up append-only writes in a way similar to how our system does: https://blog.discordapp.com/how-discord-stores-billions-of-messages-7fa6ec7ee4c7?gi=de801bddfd20#.dzqq7q4o7 https://blog.discordapp.com/how-discord-stores-billions-of-m... .
