I use apisix to encapsulate the openstack’s API to achieve high availability and rate limiting. ### Problem description My apisix configuration file (config.yaml) shows below (only shows the problem related part):  I use the stream_proxy (tcp proxy) to listen ``vip`` (provided by keepalived) and 11211, 3306 ports (related to memcached and mysql services), and then I will create ``upstream`` and ``route`` related to memcached and mysql services to achive High Availability (shown below). Notice: I observed that, for msyql and memcache services, stream_proxy (tcp proxy) must be used, otherwise (if still use the http proxy), mysql and memcache services wouldn’t work out (commands below couldn’t connect correctly). `telnet <vip> 11211` `mysql -ukeystone -pKeyStone_pwd -h<vip>` For simplicity, related upstreams has only one node: Mysql’s upstream shows blow:  Memcached’s upstream shows below:  Mysql’s stream_route (experiment shows that it’s also valid for ordinary route, but will have the same problem) shows below (matched by 3306 port and forward the service to specific node):  Memcache’s stream_route :  Then we test the mysql and memcache services, execute the command below (it shows correctly): `telnet <vip> 11211` `mysql -ukeystone -pKeyStone_pwd -h<vip>`   ### 1) Problems caused by nova-api (memcached related) Configuration related to memcached in nova.conf (if use the ``vip``, there are some problems in nova-api.log, if use specific ip, no ERROR will occur):    ### 2) Problems caused by masakari (mysql related) I alse use the ``vip`` to connect mysql in masakari configuration file (if use real ip, no ERROR will occur):   ### Summary Because I only set one node in upstream, and evidence shows that apisix is functioning correctly, but it still cause some minor problem, which seems related to stream_proxy (tcp proxy), and belows are my question about the apisix’s stream_proxy: 1.Does the stream_proxy (tcp proxy) is a short connection? And if so, it will interrupt in the client side, which will cause the server’s side to trigger some error log (refer to: https://www.jb51.net/article/57602.htm). 2.Is there any alternative solution to connect mysql and memcached with apisix? If I use the haproxy to achieve High Availability, problems above will not occur (but haproxy doesn’t have rate limiting functionality). -- This is an automated message from the Apache Git Service.
