Why companies prefer IN MEMORY DATA GRID compared to IN MEMORY DATABASES data structure? In memory database provides fast performance as it involves RAM, which operates at nanosecond. However, here, you need to bring the data from the database tier in to the application tier; again, the data transfer depends on the speed of the network, which definitely dos not match the speed of the RAM. You can speed up the whole process by adding more hardware; however, that adds to the existing cost. Alternatively, you can write Database Stored Procedures, which gets executed exceedingly fast. Nevertheless, if you do this way, it finally ends with a complex code, which we can’t manage.
IN MEMORY DATA GRID operates in a different way. As per this strategy, both the data and the application lie in the application tier. As a result, there is no need for the movement of the data and the execution happens speedily.
