-------------------------------------
Summary: Policy settings in vhostUserGroupSettings could be cached
in C code
Key: DISPATCH-1298
URL: https://issues.apache.org/jira/browse/DISPATCH-1298
Project: Qpid Dispatch
Issue Type: Improvement
Components: Policy Engine
Affects Versions: 1.5.0
Reporter: Chuck Rolke
Assignee: Chuck Rolke
As of release 0.5 when policy checking is in effect every incoming connection
performs a policy lookup and then a policy settings fetch. The settings could
be brought into C code space once to be cached and reused for the lifetime of
the associated vhost policy object.
The result would be a savings in time and space as the settings fetch is a
relatively expensive call through python, and the fetched settings are
immutable and could be shared by all connections that use them.
The down side would be managing the cached settings to be sure they are updated
and cleaned up when the associated vhost object is replaced through management
access.
