Hi, All As octavia resources increase, I found that running the "openstack loadbalancer list" command takes longer and longer. Sometimes a 504 error is reported.
By reading the code, I found that octavia will performs complex left outer join queries when acquiring resources such as loadbalancer, listener, pool, etc. in order to only make one trip to the database. Reference code: http://paste.openstack.org/show/730022 Line 133 Generated SQL statements: http://paste.openstack.org/show/730021 So, I suggest that adjust the query strategy to provide different join queries for different resources. https://storyboard.openstack.org/#!/story/2003751
