I find that in the plugin.lua。there is
` -- some plugins need to be initialized in init* phases
if is_http and core.table.array_find(http_plugin_names, "prometheus")
then
local prometheus_enabled_in_stream =
core.table.array_find(stream_plugin_names, "prometheus")
require("apisix.plugins.prometheus.exporter").http_init(prometheus_enabled_in_stream)
elseif not is_http and core.table.array_find(stream_plugin_names,
"prometheus") then
require("apisix.plugins.prometheus.exporter").stream_init()
end` in line 671. so , if we do not use the plugin prometheus, whether
the method "http_init" will be executed?
