Database replication method and apparatus for distributed system

A database replication method for a distributed system, the method comprising:

• sending, by a first partition, to a coordination server, a timestamp of a multi-partition transaction newly added to the first partition;
• receiving, by a first partition, a target timestamp from the coordination server, wherein the target timestamp is used to indicate information about a multi-partition transaction executable by the first partition, and wherein the target timestamp is based on a received timestamp of the newly added multi-partition transaction and a stored multi-partition transaction timestamp of each partition of a secondary cluster;
• and
• executing, by the first partition, a replication log in the first partition based on the target timestamp for the first partition.

A coordination server, comprising:

• a memory and a processor, wherein the memory has a plurality of computer-executable instructions stored thereon that, when executed by the processor, cause the coordination server to:
• receive a timestamp of a multi-partition transaction newly added to a first partition of a secondary cluster, wherein the newly added multi-partition transaction is a multi-partition transaction among transactions recorded in a replication log that is sent by a corresponding partition of a primary cluster and received by the first partition since the first partition last sends a multi-partition transaction timestamp;
• determine a target timestamp for the first partition based on the received timestamp of the newly added multi-partition transaction and a stored multi-partition transaction timestamp of each partition of the secondary cluster, wherein the target timestamp indicates information about a multi-partition transaction executable by the first partition;
• and
• send the target timestamp to the first partition.
