FB 将 Memcached 服务器分割成独立的池。 • wildcard pool:默认 pool 用来存储大部分数据 • small pool:存储访问频率高但 cache miss 的成本不高的数据 • large pool:存储访问频率低但 cache miss 的成本高的数据 可以看出,更新频率高的占了大部分,所

Target pool is the legacy configuration and can be used with forwarding rules for TCP and UDP traffic only. This setup creates a group of instances that need to be in the same region. You can have only one health check for each pool, and each project can have a maximum of 50 tar...

Optimizing the application code is something we have been working on actively for the past two years, but it's not a final solution. Even if you improve performance, when traffic also increases you may still need to apply the other two techniques. For the sake of this article we'll skip...

When we first increased from 16 to 256 partitions, we considered making the jump immediately to 4096. However, all of the partitions were living on a single server at the time and there were some concerns about file system performance with so many files in a single directory. On modern file...

6.5.1 Query Compilation In the last decade, various compilation approaches that satisfy different require- ments regarding compilation latency, performance, and portability emerged. Some database systems compile SQL queries by translating them to C or C++ programs that are then compiled with GCC or ...
