Hi experts
I have a requirement to cache the result of webservice call for a finite duration, I want to know which data structure should I use to cache the result. I need to store 4 columns (strings).
This requirement is similar to implementing hashmap for 2 columns of data. But in my case, the number of columns are 4. Also 1 of the column would be the timestamp.
This data structure should be sortable and I should be able to find the elements in the data structure by providing the key (column1).
