Dose galera cluster perform read load balancing?












0















Hi Now I'm doing benchmark test with several type mariadb replication with sysbench.



1 Master - 2 Slave MariaDB on kubernetes with ceph stroage.
3 Master with Galera Cluster on kubernetes with ceph storage.
sysbench attach directly each master without LB. I expect that Master-Slave and Galera Cluster's Read performance similarly. Because I know that galera dosen't perform read load balaning, only depending LB in front of Galera Cluster. But Galera-Cluster read performance is much better. below is command to run sysbench with 1 Thread.



-- 1 Master - 2 Slave --



# sysbench --db-driver=mysql --mysql-host=10.233.4.251 --mysql-user=root --mysql-password=root --mysql-db=bmt --range_size=10000 --table_size=100000 --tables=2 --threads=1 --events=0 --time=300 --rand-type=uniform /usr/share/sysbench/oltp_read_only.lua run
transactions: 4135 (13.78 per sec.)`


-- 3 Master Galera Cluster --



# sysbench --db-driver=mysql --mysql-host=10.233.25.60 --mysql-user=root --mysql-password=root --mysql-db=bmt --range_size=10000 --table_size=100000 --tables=2 --threads=1 --events=0 --time=300 --rand-type=uniform /usr/share/sysbench/oltp_read_only.lua run
transactions: 17548 (58.49 per sec.)


Maria Options such as innodb_autoinc_lock_mode, innodb_flush_log_at_trx_commit, innodb_buffer_pool_size is the same.



Could i get some advice or opinion?? Thanks.

    I'm lost -- Were you running 3 sysbenches in each test? Were any writes going on? Was there a load-balancer in use in either configuration? Were the times an average across the nodes?
