HN discussionFine, with enough replicas, you can sleep well at night. But how about the 3 years uptime without reboot? Can you really enjoy your morning coffee without thinking about it? :) Netflix went full ephemeral storage for their Cassandra clusters since the beginning, at the time when they were just spinning disks. Years later, they still insist on doing this, and had to come up with creative solution to fix the uptime is…

HN discussion(I work at Netflix on these Datastores) EVCache definitely has some sharp edges and can be hard to use, which is one of the reasons we are putting it behind these gRPC abstractions like this Counter one or e.g. KeyValue [1] which offer CompletableFuture APIs with clean async and blocking modalities. We are also starting to add proper async APIs to EVCache itself e.g. getAsync [2] which the abstractions are using und…

HN discussionWhy bring up assumptions/suppositions about Netflix's encoding process? Their tech blog and tech presentations discuss many of the requirements and steps involved for encoding source media to stream to all the devices that Netflix supports. The Netflix tech blog: https://netflixtechblog.com/ or https://netflixtechblog.medium.com/ Netflix seems to use AWS CPU+GPU for encoding, whereas YouTube has gone to the expense…
