Future upgrade for DDL service completed

Hello, Guys
We have been working hard last two weeks to make everything running again as normal.
Today, we finished upgrading the DDL service, although it might not be that big but it is better than before.
So far, this will solve many problems regarding to the DDL service. Specially, about the speed and the overload of hard disks.
