摘要
Methods, systems, and computer program products are provided for processing correlated queries in a collaborative, role-based, peer-to-peer (P2P) execution system. A correlated query is configured in accordance to a collaborative correlated query process (CQP) template. The collaborative CQP template defines roles and steps, each step being executable by one of the roles. A role is assigned to each peer node of the P2P system. A peer node having a designated role executes a step that is executable by the designated role. A message is communicated to other P2P nodes to indicate completion of the step. Another peer node having a matching role to a next step in the correlated query executes the next step in response to the message.
