I am planning to use the transit secret engine for encryption/decryption. Also it allows the user to create key using API on demand (but this is not very often).
1:) Is it possible that I build a cluster with all the nodes as active nodes (not 1 active and others standby)? I am thinking since transit engine is kind of stateless mostly, any suggestions (such as doc about this setup)?
2:) If that is not possible, can I build two clusters which share the same backend storage?
3:) Or I see the vault enterprise supports multi-server HA mode which allows all HA nodes to service read-only requests. In my situation, for transit engine traffic of encryption/decryption, is it considered as read-only request?
Thanks a lot for your replies!
