Search Typeahead Q: How much data would we need to store?
Where does the 500 million come from?
"15 % of the search queries are new" - how did you arrive at the number 15 ?
@marc_adler , your point is correct. So lets say expiry time is two weeks, then how much will be data to be stored after considering expiry time. How to come up with calculation?
Should it be 150GB for storing new data per day?
4e10 * 0.15 * 25 letter * 1 byte/letter ~= 150 GB
