The cache is a smaller, faster memory which stores copies of data from the most frequently used main memory locations and helps to reduce the average time to access memory.

JDO Caching provides the following advantages in Adeptia Suite:

  • Improves the performance of the application by serving user with cached output.
  • Decreases server round trips for fetching data from database by persisting data in the memory.
  • Reduces overhead from server resources.
