Summary
The article discusses the design considerations for a Telco Database Management System (DBMS) that must handle critical telecommunications operations like call setup, SMS, and mobile data. The author reflects on their experience designing NDB Cluster in the 1990s and how Telco requirements influenced recovery algorithms. The content covers the evolution of DBMS technologies including Google Spanner, Aurora, PolarDB, and MySQL NDB Cluster, with insights from discussions with colleague Zhao Song about the specific demands of telecommunications environments where database downtime means complete service disruption.

· 3 pulledA Telco DBMS is a DBMS that operates in a Telco environment, this DBMS is involved in each interaction with the Telco system through smartphones such as call setup, location updates, SMS, Mobile Data
If the DBMS is down it means no service
I had some interesting discussions with him on the topic and it makes sense to return to the 1990s when I designed NDB Cluster and the impact on the recovery algorithms from the requirements for a Telco DBMS
