We are using maps extensively in our architecture to map host headers to
backends. The maps are seeded dynamically with a lua handler to an external
service as requests arrive, there are no pre-seeded values in the map, the
physical map file is empty

On haproxy reload at peak traffic, the maps are emptied and I guess that is
expected. But this causes a stampede to the external service which causes
some failures.

Is there a way to prevent emptying of the map when we do an haproxy reload?
