Spider Storage EnginePerformance Test

Performance degraded as the number of records increased

• purpose of confirmation• MySQL database sharding via Spider• Confirm that performance issues caused by increasing data are resolved

• structure• sp2_r2

– 2 MySQL servers with Spider, 128(total 256) parallel execution,2 MySQL servers for real data(innodb)

• sp4_r4– 4 MySQL servers with Spider, 128(total 512) parallel execution,

4 MySQL servers for real data(innodb)• r1

– 1 MySQL server for real data(innodb), 128 parallel execution

• columns in the table• a:primary key• b:key• c:key• d:no key
