What are the advantages of using ngx_ingress_module over ngx_http_lua_module?

[tangxiao]

I find Tengine implement a C module ngx_ingress_module to dynamic load domain and certificates, instead of ngx_http_lua_module. Is there some special considerations or advantages of using ngx_ingress_module rather than lua?

ngx_ingress_module 是云原生网关tengine-ingress配套tengine的C module，支持K8s Ingress标准规范，且所有域名，路由，证书均支持无损动态生效。在功能和性能方面都远超Lua脚本。

Thanks. Is there any router-searching benchmark between ngx_ingress_module and Lua？
