Design and implementation of distributed metadata system

Abstract： With the development of enterprise business and the continuous accumulation of business data, data types are uneven, and massive data is becoming more and more difficult to handle. The metadata system emerged as a platform to improve data quality and data analysis. Metadata is now at the heart of data warehouses and business intelligence, and vendors have come up with their own solutions for metadata systems. Existing solutions currently do not support the operation of updating business data. In view of the increase in business data faced by the current metadata system, the lack of rapid expansion support, the inability to process data in time, and the problem that metadata modification cannot be synchronized and updated to business data, resulting in metadata and business data being out of synchronization, this paper provides a distributed metadata solution that supports horizontal expansion of the system and supports reverse control of business data through metadata operations. Support business generation through metadata operations.
