[Refactor] discussion of applying spring In-memory Cache to improve ordering engine

[platypus3036]

Is your feature request related to a problem? Please describe.

• In the process of mixing two types of engines, we thought spring in-memory cache could improve our engine performance.

Describe the solution you'd like

last version
KIS API Data <-> Ordering condition <-> Compare orderingQueue
=> have no reason for using Cache. only improving reading behavior couldn't be reason of using cache.
Ordering data changes almost 10 times per seconds. reading data throught cache could improve  reading speed, but another action (checking cache, searching cache, write data into the cache) could interrupt another spring process. 

Describe alternatives you've considered
Changing Data Queue type or optimizing synchronizing method could be better solution of improving engine.

Additional context
We must consider the reason why we use that skill.
