Abstract

The invention relates to a data lake schema classification method and device, equipment, a medium and a product, and the method comprises the steps: creating a queue, and initializing the queue; obtaining all fields in the at least two tables schema, and storing the fields in a queue; field types and field names of fields in the partition schema and at least two tables schema in the queue are judged in sequence; carrying out distance calculation on the fields in the partition schema and the same fields of the at least two tables schema in the queue in sequence; and determining a table schema in the corresponding queue when the distance is minimum, and merging the partitions schema into the table schema. The problem that it is difficult to determine which table schema is classified when there are at least two compatible table schema is solved. The method and the device have the effect of quickly merging the partition schema into the table schema.

Description

technical field [0001] The present application relates to the technical field of data classification, in particular to data lake schema classification methods, devices, equipment, media and products. Background technique [0002] In the unmanned driving system, it includes the original collected sensor data, labeled data, log data, etc. These different data constitute a data lake. Because each kind of data is generated every day, for the convenience of management, it is usually stored in different partitions according to date, vehicle and other information. Generally, the table structure description information corresponding to the data lake can be called a table schema, and the table structure description information corresponding to different partitions in the data lake can be called a partition schema. As time goes by, the data is constantly evolving, and there are different partition schemas in different partitions. [0003] For ease of use, compatible partition schema...
