US 11,442,961 B2 · Active transaction list synchronization method and apparatus

Abstract

An active transaction list synchronization method and apparatus comprising a first node that records, in a transaction list incremental log buffer, a transaction list incremental log that is obtained after last active transaction list synchronization, where the transaction list incremental log indicates a change of a transaction recorded in an active transaction list of the first node and includes an added-transaction log and a committed-transaction log, wherein the added-transaction log indicates a transaction is added to the active transaction list, wherein the committed-transaction log indicates a transaction is deleted from the active transaction list. When performing group commit on transactions recorded in the committed-transaction log, the first node sends the transaction list incremental log to at least one second node.

Dependent claims

An active transaction list synchronization method implemented by a first node, comprising:

obtaining a transaction list incremental log after a last active transaction list synchronization;
recording, in a transaction list incremental log buffer, the transaction list incremental log responsive to obtaining the transaction list incremental log, wherein the transaction list incremental log comprises a log that indicates a change of a transaction recorded in an active transaction list of the first node, and wherein the transaction list incremental log comprises:
an added-transaction log that indicates the transaction is added to the active transaction list;
and
a committed-transaction log that indicates the transaction is deleted from the active transaction list, wherein the active transaction list of the first node records a not-yet-committed transaction;
and
sending the transaction list incremental log to a second node when performing group commit on at least one transaction recorded in the committed-transaction log.

4 more elements

An active transaction list synchronization apparatus, comprising:

a processor;
and
a memory coupled to the processor and storing one or more programs that, when executed by the processor, cause the active transaction list synchronization apparatus to be configured to:
obtain a transaction list incremental log after a last active transaction list synchronization;
record, in a transaction list incremental log buffer, the transaction list incremental log, wherein the transaction list incremental log comprises a log indicating a change of a transaction recorded in an active transaction list of the apparatus, and wherein the transaction list incremental log comprises:
an added-transaction log that indicates the transaction is added to the active transaction list;
and
a committed-transaction log that indicates the transaction is deleted from the active transaction list, wherein the active transaction list of the first node records a not-yet-committed transaction;
and
send the log to a second node when group commit is performed on transactions recorded in the committed-transaction log.

7 more elements

An active transaction list synchronization apparatus, comprising:

a memory storing instructions;
a processor coupled to the memory and configured to execute the instructions, wherein the instructions cause the processor to:
receive a transaction list incremental log from a first node, wherein the transaction list incremental log is received after a last active transaction list synchronization, wherein the transaction list incremental log comprises a log indicating a change of the transaction recorded in the active transaction list of the first node, and wherein the transaction list incremental log comprises:
an added-transaction log that indicates the transaction is added to the active transaction list;
and
a committed-transaction log that indicates the transaction is deleted from the active transaction list, wherein the active transaction list of the first node records a not-yet-committed transaction;
and
update a local active transaction list according to the transaction list incremental log.
