English to French Art/Literary General / Conversation / Greetings / Letters article sur l'informatique (la consistance éventuelle)

The article appears on a computing blog. The author refers to several variations of the eventual consistency model (causal, read-your-writes, session, monotonic read and montonic write consistency). He continues:
A number of these properties can be combined. For example, one can get monotonic reads combined with session-level consistency. From a practical point of view these two properties (monotonic reads and read-your-writes) are **most desirable** in an eventual consistency system, but not always required. These two properties make it simpler for developers to build applications, while allowing the storage system to relax consistency and provide high availability.

I’m unsure as to whether he means:

ces deux propriétés (lectures monotoniques et « lecture de vos écritures ») sont très souhaitables dans un système de consistance éventuelle, mais pas toujours exigées.

OR

…sont les plus souhaitables dans un système de consistance éventuelle…
