补上作业,MariaDB10和MySQL5.6社区版压力测试,见下图: sysbench(10.8.8.43) MySQL5.6和MariaDB10.0.11(10.8.8.100) 压力测试参数: sysbench--test=oltp--mysql-table-engine=innodb--oltp-table-size=10000000--max-requests=0--max-time=900--num-t
补上作业,MariaDB10和MySQL5.6社区版压力测试,见下图:
sysbench(10.8.8.43)
MySQL5.6和MariaDB10.0.11(10.8.8.100)
压力测试参数:
sysbench --test=oltp --mysql-table-engine=innodb --oltp-table-size=10000000 --max-requests=0 --max-time=900 --num-threads=512 --mysql-host=10.8.8.100 --mysql-port=3308 --mysql-user=admin --mysql-password=123456 --mysql-db=test run
1千万记录,不限制请求,压测15分钟,并发连接数512个。
my.cnf参数:
sync_binlog = 0 innodb_flush_log_at_trx_commit = 0 innodb_flush_method = O_DIRECT innodb_flush_neighbors = 1 innodb_buffer_pool_size = 20G innodb_io_capacity = 500 innodb_log_file_size = 512M innodb_log_files_in_group = 3 innodb_log_buffer_size = 16M tx_isolation = READ-COMMITTED thread_handling = pool-of-threads(MariaDB的线程池)
机器配置:
比较差,DELL R610,2颗4核CPU,RAID1(WriteBack策略)7200转SAS硬盘。
读写测试
可以明显的看到,在高并发的时候,MySQL5.6.19的性能减少了50%。
下面是top和压力测试截图:
MySQL5.6.19
load average达到195,已经超负荷。
TPS为每秒1002.42个。
MariaDB10.0.11
load average为11.59
TPS为每秒2044.80个。
补充:现在把并发连接数调成了900个,再压一次,看看TPS:
MySQL5.6.19
MariaDB10.0.11
可以看到,随着并发连接数的增加,MySQL5.6性能持续下降,而MariaDB10,性能保持平稳。
结论:
大体和官方的测试差不多,因手里没有MySQL5.6的企业版,所以不能说MariaDB10就一定强,但在高并发环境,MySQL5.6.19社区版不建议使用在生产环境上。

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
