La colonne
Tester les performances de mysql5.7 et mysql8.0 dans différentes conditions de concurrence en lecture-écriture, en lecture seule et modes en écriture seule. (tps, qps)

Sous différentes stratégies de persistance (binlog, persistance du journal redo) mysql5.7 et mysql8.0 lisent et écrivent Performances en mode, mode lecture seule, mode écriture seule (oltp_read_write, oltp_read_only, oltp_write_only)
le temps de test sysbench est de 60 s et le nombre de tables testées est de 20
Les tests ont été réalisés en mode double 1 (sécurité) et en mode 0 2 (haute performance)

mysql5.7和mysql8.0 在只写模式下的表现
sysbench 需要设置--db-ps-mode=disable 禁用预编译语句,不然并发测试线程多时会报下面的错误
FATAL: mysql_stmt_prepare() failed FATAL: MySQL error: 1461 "Can't create more than max_prepared_stmt_count statements (current value: 16382)" FATAL: mysql_stmt_prepare() failed FATAL: MySQL error: 1461 "Can't create more than max_prepared_stmt_count statements (current value: 16382)" FATAL: thread_init' function failed: /usr/local/share/sysbench/oltp_common.lua:288: SQL API error FATAL: mysql_stmt_prepare() failed FATAL: MySQL error: 1461 "Can't create more than max_prepared_stmt_count statements (current value: 16382)" FATAL:thread_init' function failed: /usr/local/share/sysbench/oltp_common.lua:288: SQL API error FATAL: mysql_stmt_prepare() failed复制代码
