What type of memory overhead does each tenant database incur initially?

The correct answer indicates that each tenant database incurs an initial memory overhead of approximately 100MB. This figure is significant as it reflects the resources needed to establish a new tenant database within Trend Micro Deep Security's multi-tenant architecture. This overhead is necessary to allocate space for the database system itself, including metadata, system tables, and initial configuration settings that are fundamental to ensuring the database functions correctly and efficiently from the onset.

It's important to recognize that the specified memory footprint is crucial for effective database operations and performance. Initiating with an adequate amount of resources prevents performance bottlenecks and ensures that multiple tenant databases can operate concurrently without issues related to memory shortage.

Memory overhead considerations are particularly relevant in environments where multiple tenant databases are deployed, as each database needs to maintain its separate resources while allowing administrators to manage them collectively. This initial overhead supports stability and responsiveness for users accessing various tenant environments.

Understanding the specific memory requirements aids organizations in planning their infrastructure and resource allocation effectively, ensuring they have the necessary capacity to support their operations as they scale.
