This will use more memory, but now you should achieve almost 100 % cpu
utilization even with a map based data structure storing the data.

Right now it seems if a lock is done before setting a value in a map
then it seems the entire map is locked preventing write to some other keys
as well.
[...]Is it possible to do a lock only at the key level(using any sync
mechanism or using some additional data-structure for keys) in any look-up
data structure so that writing to some other keys other than the one in
which lock is held can proceed without getting blocked?
