Why Traditional (on disk) DB when we have InMemory DB?
Hi,
When In-memory DB does have lot of advantages in it as there wont be any file I/O or Disk I/O and reduces the CPU cycles as well as memory consumption and more importantly stores terabytes of data. Its durability is also really good in crashes we can log all the details in a transactional logging to be retrieved later.
In such case why we need to go for a On disk or traditional DB systems? As there are so many advantages with In memory DB? Please clarify.
Thanks.
