Question regarding preferred Storage Backend(s) for large k/v store (up to 50 million secrets)

Hi Becca,
thanks a lot for your reply.

I had a quick look at consul while researching the different storage backends and found a paragraph in the KV description that made me cautious:

Consul KV allows users to store indexed objects, though its main uses are storing configuration parameters and metadata. Please note that it is a simple KV store and is not intended to be a full featured datastore (such as DynamoDB) but has some similarities to one.

I have never worked at this scale (in terms of number of secrets) with neither vault nor consul. Do you think, that consul (with a moderate number of servers/nodes) can handle this amount of secrets?

Many thanks in advance
Cheers - Julian
