Abstract

The embodiment of the invention belongs to the field of big data, and relates to a data dependency judgment method which comprises the following steps: acquiring batch processing jobs transmitted among data tables in a database and a dependency relationship of the batch processing jobs, and grouping the batch processing jobs according to the dependency relationship; constructing a connected graph of the batch processing jobs according to the groups; and determining whether a strongly connected component exists in the connected graph or not, and when it is determined that the strongly connected component exists in the connected graph, determining that a data dependent loop exists in the database. The invention further provides a data dependency judgment device, computer equipment and a storage medium. In addition, the invention also relates to a block chain technology, and the connected graph can be stored in a block chain. According to the invention, the data dependency judgment efficiency and accuracy are improved.

Description

technical field [0001] The present application relates to the technical field of big data, and in particular to a data dependency judgment method, device, computer equipment and storage medium. Background technique [0002] Databases often contain a large number of batch job tasks, which have various start mechanisms. And table calls between batch job tasks are unavoidable. For example, if the batch task P1 generates a data table T1, if the batch job task P2 wants to use the data in the data table T1, it must wait for the end of P1 to start P2. Otherwise, the data base T1 for P2 calculation is incomplete, and P2 calculation results may be wrong. [0003] In an actual scenario, there may be N1 result tables of P1, and N2 basic tables of P2. At this point in the entire database, the dependencies of all batch jobs become a complex network graph. At this time, a deadlock situation may occur: P1 needs the result table T2 of P2 as the calculation basis, and P2 needs the result...
