Hi Monks, I have a csv file which has about 100mb 60k rows and has 10 columns.The first 2 colmns are the key. I need to load it into memory and based on keys passed in externally find the matched row and extract some data to do some calculations. The external input will come in with about 5k keys. I'm curious what is the most efficient method for getting this done? Thanks in advance
