Efficient and scalable transaction processing using a consensus-based transaction model

A computing device, comprising:

• a memory;
• and
• a processor device coupled to the memory to:
• receive a transaction comprising a plurality of update subtransactions to be performed against a corresponding plurality of resources;
• determine a transaction identifier (ID) that corresponds to the transaction;
• for each resource of the plurality of resources:
• send the transaction ID to a resource manager associated with the resource to determine a status of the corresponding subtransaction as one of 1) a not seen status, 2) a prepared status, or 3) a committed status;
• and
• based on the status of the corresponding update subtransaction, perform any action against the resource via the resource manager that is necessary to bring the status of the corresponding update subtransaction to the committed status;
• and mark the transaction as being completed.

A computer program product stored on a non-transitory computer-readable storage medium and including instructions configured to cause a processor device to:

• receive a transaction comprising a plurality of update subtransactions to be performed against a corresponding plurality of resources;
• determine a transaction identifier (ID) that corresponds to the transaction;
• for each resource of the plurality of resources:
• send the transaction ID to a resource manager associated with the resource to determine a status of the corresponding update subtransaction as one of 1) a not seen status, 2) a prepared status, or 3) a committed status;
• and
• based on the status of the corresponding update subtransaction, perform any action against the resource via the resource manager that is necessary to bring the status of the corresponding update subtransaction to the committed status;
• and
• mark the transaction as being completed.
