Memory estimates: Calculation -

The calculation in documentation is based on how many users read in 24 hours. Shouldn't it be based on how many users actually create the new URL's instead. Do I have some different understanding?
Instead of -
20K * 3600 seconds * 24 hours = ~1.7 billion
0.2 * 1.7 billion * 500 bytes = ~170GB
should it be -
~200 * 3600 seconds * 24 hours = 17.28 Million
0.2 * 17.28 * 500bytes = Approx 1.7 GB.
Ultimately - we have only 17.28 new URL created in 24 hours.

Hi @Sachin Puranik, I have the same thought too. It seems to me that memory calculation should be "write request (QPS)" times "Cache-Expiration-Time (TTL)" since the cached data are from written/created data. Let's say the cached data can stay in cache 10 days only, the...
