[discussion]should we improving algorithmic performance about LRU

[litao]

Hi
In carbondata LRU are used for cache,under CarbonLRUCache the  algorithmic
is LRU-1.
can we improve the algorithmic like LRU-2,Algorithm comparison
under https://blog.csdn.net/elricboa/article/details/78847305
If we improve
the LRU Algorithm,the performance of index hit will be improved.alse it
helps to Improving query efficiency.

Another question,if we can share the
cahe to all of the drivers,it is no need to build multiple for each driver.
it is another question we should discuss

hi sraghunandan,
thank you for your question.
you can see the difference between LRU-1 to LRU-2 under
https://blog.csdn.net/elricboa/article/details/78847305
it is in chinese.
