Data synchronization method and device, computer equipment and storage medium

The invention relates to a data synchronization method and device, computer equipment and a storage medium, and relates to the technical field of internet information. The method comprises the steps of obtaining a data table type of at least one target data table; the target data table is a data table to be synchronized from the source database to the target database; in response to the fact that the data table type indicates that at least one target data table contains an LOB data table, obtaining a data mode of an LOB field value in the LOB data table; the data mode is used for indicating the memory capacity occupied by the LOB field value in the LOB data table; and performing a synchronization operation on the LOB data table based on the data mode of the LOB field value. According to the method, the synchronization of the LOB data tables between the heterogeneous databases is realized, and the problem that the LOB type data cannot be synchronized between the heterogeneous databases is solved, so that the d
