System and method for processing a request to perform an activity associated with a precompiled query

A method for processing a query request, comprising:

• receiving, at a first slave node and a second slave node, a request communicated over a communication channel by at least one master node,
• each of the first and second slave nodes being coupled to the at least one master node,
• the request comprising a request to perform an activity associated with a precompiled query;
• communicating, from the first slave node, a first notification over the communication channel indicating that the first slave node is processing the request;
• receiving, at the second slave node, the first notification;
• communicating by the second slave node, a second notification over the communication channel indicating that the second slave node is handling the request;
• receiving, at the first slave node, the second notification;
• and
• initiating, at the first or second slave node, an arbitration to determine whether the first or second slave node is entitled to process the request,
• wherein a winner of the arbitration between the first and second slave nodes continues processing the request and a loser of the arbitration between the first and second slave nodes ceases processing the request.

A computer-readable medium storing program instructions for processing a query request according to a method, the method comprising:

• receiving, at a first slave node and a second slave node, a request communicated over a communication channel by at least one master node,
• each of the first and second slave nodes being coupled to the at least one master node,
• the request comprising a request to perform an activity associated with a precompiled query;
• communicating, from the first slave node, a first notification over the communication channel indicating that the first slave node is handling the request;
• receiving, at the second slave node, the first notification;
• communicating, by the second slave node, a second notification over the communication channel indicating that the second slave node is handling the request;
• receiving, at the first slave node, the second notification;
• and
• initiating, at the first or second slave node, an arbitration to determine whether the first or second slave node is entitled to process the request,
• wherein a winner of the arbitration between the first and second slave nodes continues processing the request and a loser of the arbitration between the first and second slave nodes ceases processing the request.
