Transaction data import method and device and server

The invention provides a transaction data importing method and device and a server, and is applied to the technical field of big data. Based on the method, during specific implementation, after a transaction system server obtains a transaction log file of a current time period of a day, transaction data contained in the transaction log file of the current time period of the day can be split into a plurality of import files according to a user identifier of a user object; wherein each import file at least comprises one piece of transaction data; each import file corresponds to one user group; according to a preset table insertion processing rule, the transaction data contained in the multiple import files are imported into corresponding database tables of the day in the distributed database through a database table record table of the distributed database; and updating a database table record table of the distributed database. Therefore, the transaction data can be efficiently, accurately and automatically imp
