有一个问题:mysql cluster的数据会放到内存里面,大数据量需要分库分表的话那得多大的内存?
有意思,那看看这个:
So how will MySQL Cluster work on a
Niagara-II with 256 GB memory?
Unpublished results from 2002
* Benchmark load:
* Simple read, read 100 bytes of data through primary key
* Simple update, update 8 bytes of data through primary key
* Both are transactional
* HW: 72-CPU SunFire 15k, 256 GB memory
* CPU’s: Ultra Sparc-III@900MHz
* 32-node NDB Cluster, 1 data node locked to 1 CPU
* Results (Database size = 88 Gbyte, ~900 million records):
* Simple Read: 1.5 million reads per second
* Simple update: 340.000 updates per second |
