Systems and methods for key-value transactions

A method for interleaving high priority key-value transactions together with lower priority transactions over a shared input-output medium, comprising:

• detecting, by a medium controller associated with a shared input-output medium, that a second packet associated with high priority key-value transactions is pending;
• stopping, as a result of said detection, by said medium controller, handling of a first packet associated with a lower priority transactions via said shared input-output medium;
• and
• commencing, by said medium controller, transmission of said second packet via said shared input-output medium,
• thereby preventing said lower priority transactions from delaying said high priority key-value transactions and thereby interleaving the high priority key-value transactions with the lower priority transactions.

A method for interleave high priority key-value transactions together with lower priority transactions over a shared input-output medium, comprising:

• detecting, in a medium controller associated with a shared input-output medium, that a second packet associated with high priority key-value transactions is pending;
• delaying, as a result of said detection, by said medium controller, handling of a first packet associated with a lower priority transactions via said shared input-output medium;
• and
• transmitting instead, by said medium controller, said second packet via said shared input-output medium,
• thereby preventing said lower priority transactions from delaying said high priority key-value transactions and thereby interleaving the high priority key-value transactions with the lower priority transactions.

A method for interleaving high priority key-value transactions together with lower priority transactions over a network-interface-card, comprising:

• receiving, in a first network-interface-card (NIC), from a first compute element, a new request to extract with high priority a first value associated with a first key, in which the new request is associated with a high priority key-value transaction;
• consequently
• delaying, in said first network-interface-card, a lower priority transaction or other network-related activity—that prevents said first network-interface-card from immediately communicating said first key to a destination server storing said first value and belonging to a key-value-store comprising a plurality of servers;
• and
• communicating the first key immediately, as a result of said delaying, from said first network-interface-card to said destination server, thereby allowing said destination server to start immediately processing of said first key as required for locating, within said destination server, said first value in conjunction with said new request and thereby interleaving the high priority key-value transaction with the lower priority transaction.
