Description Terry Wilson 2024-05-10 20:21:41 UTC 
Description of problem:

Octavia spawns a new "driver" with every API request. The driver code starts a new OVSDB connection, which in turn transfers the database contents across the network and stores them locally in memory, only to be thrown away at the end of the request.

This makes these API requests *incredibly* expensive and can lead to timeouts on large installs.

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


How reproducible:
100%

Steps to Reproduce:
1. Make an API request with a large OVSDB DB
2. Note that it takes a long time and ovsdb-server gets pretty busy

Actual results:
The API requests time scales with the database size (example, 50MB ovsdb, minimum API request time was 12 seconds)

Expected results:
The API request time is significantly less, monitoring OVSDB traffic after the initial request should not show a new DB dump
