commit c6cee9207349a12e499cbc81fe0e5d4d5bfa015c Author: Brian Haley <[email protected]> Date: Tue Apr 7 15:54:57 2020 -0400 Spawn long-running processes in the driver agent The OVN Octavia provider driver in the OvnProviderHelper class caches these attributes: ovn_nbdb_api_for_events ovn_nb_idl_for_events ovn_nbdb_api to not re-create things each time OVN IDL that is used for handling events is called. We should be using the Octavia Driver Provider Agent framework instead to not have those long-running IDLs in the API process. This change: - Creates driver provider agent and registers its entry point - While setting up the driver agent instance, start IDL that will handle events - Stop caching ovn_nbdb_api, ovn_nb_idl_for_events and ovn_nbdb_api_for_events in the OvnProviderHelper class Change-Id: I0034a48997bd6b95e1b51bfcbd56e8372b35e62f Closes-bug: #1871355 ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo!

Now we are able to use Octavia Driver Agent [2] instead to not have those long-living IDLs in API process.
