What is a common drawback of implementing summary replication?

Implementing summary replication often leads to redundant data storage as it requires duplicating summary data from the primary server to one or more secondary servers. This duplication is necessary to ensure that the summary data is available for reporting and analytics without affecting the performance of the primary system. While having multiple copies of summary data can improve accessibility and redundancy, it also means that storage resources are being utilized inefficiently, which can increase overall costs and complexity in managing the data.

In environments where multiple systems are being replicated, managing these redundant copies can add to operational overhead and complicate data management strategies. The need for strategies to handle and maintain this redundant storage can further lead to potential challenges in ensuring data integrity and consistency across systems, making it a notable drawback of summary replication.
