This invention discloses a data synchronization method, system, electronic device, and medium for a distributed cluster. The data synchronization method includes: detecting whether all nodes have the same expected update time for the next incremental data update at the current moment; the expected update time is determined based on the moment when the data source performed an incremental data update in the previous moment; for nodes with an expected update time, using the expected update time as the determination time for the node to perform an incremental data update in the next moment; when the current moment reaches the determination time, controlling each node to obtain the latest incremental data from the data source to update the historical data of each node. This invention uses the update time of the data source's next incremental update as the determination time for each node's next data update, ensuring that the update time of each node remains consistent, guaranteeing consistent data updates across all nodes in the distributed cluster, and reducing latency between nodes and the data source.

Embodiments of the present disclosure provide a data pushing method and device, equipment and a storage medium. The method comprises: obtaining first target data from a data source based on a data subscription request of a business party; pushing the first target data into a message queue of the business party; obtaining second target data from the data source based on the data subscription request; correcting the first target data in the message queue based on the second target data, so that the business party reads the corrected first target data from the message queue. According to the embodiments of the present disclosure, the first target data in the message queue is corrected by the second target data, which can ensure that the data pushed to the business party is consistent with the data in the data source, and improve the accuracy of data pushing.
