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
Ideally master node should receive ANY TYPE of query and stand by nodes just SELECTS. But in case i have 2 nodes cluster then such solution won’t load balance anything because: if i choose alias MASTER i will be redirected to MASTER node only if i choose alias SLAVE...

在一个region内部会让storage cluster负责cache数据失效的功能,在每个MySQL数据库中部署一个Mcsqueal(守护进程)用于负责cache数据失效,通过从commit log提取sql删除语句,批量广播到前端集群,Mcsqueal并不是直接把删除操作广播到所有的Memcache server中,而是通过先转发某些特定机器的Mcrouter中,由Mcrouter根据key转发到相应的...
This proxy object in turn determines what host a query is sent to based on the methods called, removing the need for parsing SQL queries. Sticky connections Sticky connections are supported by storing a pointer to the current PostgreSQL WAL position the moment a write is performed. This pointer...
A subset of the databases is put into an elastic pool. An Elastic Database job runs T-SQL scripts against all databases. The split-merge tool is used to move data from one shard to another. The Elastic Database query allows you to write a query that spans all databases in the shard ...
insql_class.h. The THD is a large data structure which is used to keep track of various aspects of execution state. Memory rooted in the THD will grow significantly during query execution, but exactly how much it grows will depend upon the query. For memory planning purposes we recommend ...
So, we have SQL and LINQ. We also have bulk and as I said, you can do Indexing. Runtime Data Sharing I am just going to very quickly… there's key based events, there's cache level events, there's pub sub events, there's a continuous query. ...
