Semisynchronous replication falls between asynchronous and fully synchronous replication. The source waits until at least one replica has received and logged the events (the required number of replicas is configurable), and then commits the transaction.
The control plane operations (e.g., promotions, failover, and membership change) would be the responsibility of a set of Python daemons (henceforth called automation).
這個方法常遇到的問題是切換 primary server (以前叫做 master server) 時有可能會因為 binlog position 接不起來而失敗。
所以後來 MySQL 導入了 GTID，可以緩解這個問題，但還是有可能會發生不同的 secondary server (以前叫做 slave server) 會有不一樣的資料。
而在 Meta 改出來的架構裡面，把 replication data 直接寫到一個用 Raft 同步的系統，同步到其他的 secondary server 上面：
In MySQL Raft:
Primary writes to binlog via Raft, and Raft sends binlog to followers/replicas.
Replicas/followers receive in binlog and apply the transactions to the engine. An apply log is created during apply.
Binlog is the replicated log from the Raft point of view.

試著用 llama.cpp 跑，65B 的 model 在家裡桌機有 64GB RAM 的情況下是可以應硬扛的，跑降到 4bits 的 model 大約吃 41GB RAM 左右。
比較驚訝的是 efficient 這個部份，拿 CPU 跑 65B 版本是跑得動的。
隨便丟個「文字接龍」進去 LLaMA-65B 讓他接，可以看到接出來的東西還可以：
main: prompt: 'The main difference between javascript and java are '
main: number of tokens in prompt = 10

The main difference between javascript and java are 1)Java is a compiled language while JavaScript
is not. So that the performance of Javascript code can be lower than Java Code, but they run on different platforms: browser vs server or local machine;
2)'javac' to compile .java file to bytecode(for JVM), and 'jar'(to make executable jar files for client systems).
3)Java uses more memory (RAM) that javascript. So the Javascript code is generally small than Java
codes.(A web application written in JavaScript may run faster on a PC with 64 MB of RAM compared to one running using applets.) While an advantage offered by J
如果是 LLaMA-7B 的話會快很多，但回答就有點微妙了：
main: prompt: 'The main difference between javascript and java are '
main: number of tokens in prompt = 10
[...]
The main difference between javascript and java are 1) Javascript is interpreted, while Java compiles to native machine code. (Compiled languages have a performance advantage over Interpreted ones
.)
2) The language standardization process for JavaScript has not been completed at the time of this writing which leaves it open to being hacked or changed by those who care enough about your website to do so... In Java, everything is set in stone. (Or at least as much code that can be shipped on a CD-ROM disk)
Sorry if my response was not clear - but you're right! I think that "2" above should really have said: "(
At any given point on the y-axis, SVT-AV1 can maximize encoding speed compared with any other production encoder. For example, the M8 preset is about as efficient as libvp9 preset 0, but M8 is almost 10 times faster.
Two major open source software decoders are compatible with multiple platforms: dav1d was developed by VideoLAN and the open source community and can serve as an app-level decoder, while Google’s libgav1 is integrated into the Android SDK.
[W]e decided to integrate dav1d into the player for both iOS and Android platforms.
