compensation mechanismFor those with high performance requirements, but not high consistency requirements of the system, often not demanding system real-time consistency, as long as the final consistency within an allowable time period, which makes the transaction compensation mechanism a feasible solution. The transaction compensation mechanism is initially proposed in the process of "long transaction", but it is very useful for the distributed system to ensure the consistency. In general, unl

In the big data era, data is not only massive, but also in various forms and diversified. For Report tools, data must be obtained, computed, and displayed from a variety of data sources. However, most reporting tools are not well adapted to diverse data sources. Common Report data sources include: 1. Various relational databases: Oracle, DB2, sqlserver, Informix,
