Classification: CPC G | IPC G

Claim 5:
6. The system of claim 1, further comprising a transaction manager node that is configured to:
generate a root transaction start identifier of a root transaction, associated with the data of the dataset, under which the statement-level transaction having the statement-level identifier is nested;
wherein each of the plurality of compute nodes are configured to:
locally commit individual task-level modifications to the data, having associated task-level nested identifiers, made by ones of the portions of the at least one task that complete successfully thereat, said locally commit individual task-level modifications being performed independently of communications with the transaction manager node; and
wherein the distributed query processor is configured to:
locally commit each of the task-level modifications to the data, as associated with a corresponding vertex-level nested identifier of a vertex of the vertices under which the ones of the portions of the at least one task are performed based on successful completion thereof, said locally commit each of the task-level modifications being performed independently of communications with the transaction manager node, and
initiate distributed performance at the plurality of compute nodes of next portions of at least one next task in a next vertex of the vertices that depends from the vertex and that has another corresponding vertex-level nested identifier that is newer than the corresponding vertex-level nested identifier of the vertex.
