   > Generally this has to do with how discrete the requests are on your API 
service, which is related to multiple metrics such as route_id, resp_code, or 
even consumer_id, etc. 
(https://apisix.apache.org/docs/apisix/next/plugins/prometheus/#labels) 
Multiply them together and that's the number of record entries you'll get, 
which in the prometheus or observability is called a high cardinality. If 
they're really large, you'll need to increase the metrics size.
   
   Will it be okay if we increase the lua_shared_dict - prometheus-metrics 
parameter value to 512m or 1024m?
