[Resource Configuration] Can OpenResty achieve load balancing?
[Attachment: Screenshot / Log / Monitoring]
You can use LB components like haproxy, or you can use the official LB TiProxy. Of course, using openresty for reverse proxy is also okay.
For software, use HAProxy; for hardware, use F5 and other load balancers.
Our approach is to add a layer of Haproxy reverse proxy in front of TIDB Serve. The application just needs to connect to Haproxy. You can refer to this.
Not yet, but TiDB Cloud is available as a feature for external services.
I am also looking into this load balancing. I am not sure if the tidb-loadbalance client load balancing can be used in a production environment.
TiDB itself currently does not have a general tidb-server load balancing component. The official recommendation is to use third-party components for load balancing. Options include nginx or haproxy+keepalived or other LB tools, as long as they can distribute client traffic evenly to different tidb server nodes.
You can consider implementing it in hardware or software. The front-end application manually configures different nodes.
