How does the number of object instances affect the architecture and efficiency of an application?

Answer from AI
The number of object instances directly affects the architecture and efficiency of an application for several reasons:
-
Memory: Each instance consumes memory. A large number of objects can lead to increased memory usage and, consequently, the need for optimization or the use of patterns such as object pools.
-
Performance: Creating and destroying a large number of objects can impact performance due to allocation and garbage collection costs.
-
Architecture: Architecture is often built considering the lifecycle of objects. For example, singletons or factories help control the number of instances.
-
Parallelism: In Go, where goroutines are actively used, the number of objects can influence synchronization and data safety.
Example: if you have a structure representing a database connection, creating a large number of such objects can lead to resource wastage. Instead, a connection pool is used, where the number of instances is limited and managed centrally.
