Description Yadnesh Kulkarni 2023-07-04 11:52:16 UTC

Description of problem:
In osp18 we no longer expose memcached to compute nodes. In 16/17 compute nodes can connect to memcached in controller nodes but it's not recommend. It can cause too many connections in case compute nodes are scaled out, and it can also cause undesired latency in DCN.

Objective is to cache project and user names in oslo's dictionary backend.

Version-Release number of selected component (if applicable):
17.1

# DEPRECATED: Password for connection to XenServer/Xen Cloud Platform. (string
# value)
# This option is deprecated for removal.
# Its value may be silently ignored in the future.
# Reason: Support for XenServer/Xen Cloud Platform has been deprecated
#connection_password = <None>
