Keliru dengan mysql clustering

Recommended Posts

Mungkin dalam ni ada yang pernah deploy atau testing mysql cluster.

Setting sekarang yang tengah simulate macam ni;

[root@db1 mysql-cluster]# ndb_mgm -e show
Connected to Management Server at: localhost:1186
Cluster Configuration
[ndbd(NDB)]     2 node(s)
id=2    @  (mysql-8.0.21 ndb-8.0.21, Nodegroup: 0, *)
id=3    @  (mysql-8.0.21 ndb-8.0.21, Nodegroup: 0)

[ndb_mgmd(MGM)] 1 node(s)
id=1    @  (mysql-8.0.21 ndb-8.0.21)

[mysqld(API)]   2 node(s)
id=4    @  (mysql-8.0.21 ndb-8.0.21)
id=5    @  (mysql-8.0.21 ndb-8.0.21)



1. Kalau nak add cluster bagi high performance macam load balancing server mana perlu add, data node[ndbd(NDB)] atau mysql node[mysqld(API)]

2. Antara cluster dengan master/slave replication yg mana lebih baik untuk handle load balancing.
