System and method for sending and receiving remote procedure calls

1. A method, comprising:

receiving, by one or more computing devices elected to operate as a lease leader, a first Remote Procedure Call (RPC), the first RPC comprising a message and a leader lease duration;

creating, by the one or more computing devices, a second set of RPCs each including a respective portion of the message in the first RPC;

revising, by the one or more computing devices, the message in the first RPC to replace the message with a reference to each RPC of the second set of RPCs;

sending, by the one or more computing devices, the first RPC with the references;

sending, by the one or more computing devices, the second set of RPCs;

receiving, by the one or more computing devices, one or more acknowledgements indicating that one or more RPCs of the second set of RPCs were received; and

extending, by the one or more computing devices in response to receiving one or more acknowledgements within a predetermined period of time, the duration of the leader lease for the one or more computing devices.

2. The method of claim 1 , further comprising:

prior to sending the entire second set of RPCs, receiving, by the one or more computing devices, timing information indicating when one or more RPCs of the second set of RPCs were received; and

changing, by the one or more computing devices, a size of one or more remaining RPCs in the second set of RPCs based on the timing information.

3. The method of claim 1 , further comprising:

determining, by the one or more computing devices, a size of the message in the first RPC, wherein creating the second set of RPCs is based on the size of the message in the first RPC.

4. The method of claim 1 , wherein each second RPC of the second set of RPCs includes a respective identifier referencing the first RPC.

5. The method of claim 1 , wherein the second set of RPCs is created as an ordered sequence, and each of the second set of RPCs includes a number indicating a position in the ordered sequence.

6. The method of claim 1 , further comprising:

determining, by the one or more computing devices, whether any of the one or more acknowledgements is not received within a predetermined time period;

performing, by the one or more computing devices, an action based on determining that any of the one or more acknowledgements is not received within the predetermined time period.

7. The method of claim 6 , wherein the action comprises canceling the sending of the second set of RPCs.

8. The method of claim 6 , wherein the action comprises relinquishing responsibility for sending the second set of RPCs to one or more other computing devices.

9. The method of claim 6 , wherein the action comprises extending the duration of the leader lease.

10. The method of claim 1 , further comprising:

receiving one or more acknowledgements indicating that one or more RPCs of the second set of RPCs was received;

determining whether any of the one or more acknowledgements is not received within a predetermined time period; and

performing an action based on determining that any of the one or more acknowledgements is not received within the predetermined time period.

11. A system, comprising:

two or more computing devices, including a first computing device elected as a lease leader and one or more additional computing devices;

wherein the first computing device is configured to:

receive a first Remote Procedure Call (RPC), the first RPC comprising a message and a leader lease duration;

create a second set of RPCs each including a respective portion of the message in the first RPC;

revise the message in the first RPC to replace the message with a reference to each RPC of the second set of RPCs;

send the first RPC with the references;

send the second set of RPCs;

receive, from the one or more additional computing devices, one or more acknowledgments indicating that one or more RPCs of the second set of RPCs were received; and

extend, in response to receiving one or more acknowledgements within a predetermined period of time, the duration of the leader lease for the first computing device.

12. The system of claim 11 , wherein the first computing device is further configured to:

prior to sending the entire second set of RPCs, receive timing information indicating when one or more RPCs of the second set of RPCs were received; and

change a size of one or more remaining RPCs in the second set of RPCs based on the timing information.

13. The system of claim 11 , further comprising:

determining, by the one or more computing devices, a size of the message in the first RPC, wherein creating the second set of RPCs is based on the size of the message in the first RPC.

14. The system of claim 11 , wherein each second RPC of the second set of RPCs includes a respective identifier referencing the first RPC.

15. The system of claim 11 , wherein the second set of RPCs is created as an ordered sequence, and each of the second set of RPCs includes a number indicating a position in the ordered sequence.

16. The system of claim 11 , wherein the first computing device is further configured to:

determine whether any of the one or more acknowledgements is not received within a predetermined time period; and

perform an action based on determining that any of the one or more acknowledgements is not received within the predetermined time period.

17. The system of claim 16 , wherein the action comprises canceling the sending of the second set of RPCs.

18. The system of claim 16 , wherein the action comprises relinquishing responsibility for sending the second set of RPCs to one or more other computing devices.

19. The system of claim 16 , wherein the action comprises extending the duration of the leader lease.

20. The system of claim 11 , wherein the first computing device is further configured to:

Receive one or more acknowledgements indicating that one or more RPCs of the second set of RPCs was received;

determine whether any of the one or more acknowledgements is not received within a predetermined time period; and

perform an action based on determining that any of the one or more acknowledgements is not received within the predetermined time period.
