One-phase commit for distributed transactions

A computer-implemented system, comprising:

• a plurality of nodes configured to participate in processing a distributed transaction, the plurality of nodes including
• a transaction coordinator (Tx), and
• a plurality of transaction participants (CcMap shards);
• and
• a global log (Txlog) configured to serve as a centralized authority for managing liveness of the plurality of nodes,
• wherein the transaction coordinator (Tx) is configured to:
• perform a single logging operation at the global log (Txlog);
• determine, based on the result of a single logging operation whether all of the plurality of nodes, participated in distributed transaction, are ready to proceed with a commit decision;
• and
• communicate:
• a final commit decision to the plurality of transaction participants when the global log(Txlog) confirms that all of the plurality of nodes are ready;
• or,
• an abort decision to the plurality of transaction participants when the global log (Txlog) indicates that any of the plurality of nodes is not ready;
• wherein the liveness of each of the plurality of nodes identifies an operational lifetime of the corresponding node within the computer-implemented system, and is characterized by a unique liveness number;
• wherein global in global log (Txlog) denotes the centralized nature of the TxLog logging service, which is accessible by all nodes in the transaction system and serves as the authoritative source for the each node liveness and transaction commit status, the global log maintains a unified system-wide view of transaction state across all nodes, to ensure commit or aborted atomically, even in the presence of node failures, and wherein the centralized logging service reduces the complexity and overhead associated with maintaining local logs at each individual node, thereby improving the system's resilience and availability.
