In computing, memoization or memoisation
is an optimization technique used primarily
to speed up computer programs by storing
the results of expensive function calls and  
returning the cached result when the same
inputs occur again.

A handful of BigQuery SQL queries that you can use to analyze your own Google Analytics for Firebase data. To find out more about how they work, check out our presentation from Cloud Next 2018 (Video link to be added soon)

Please note that these scripts have been updated to make sure of the new Firebase schema, which was rolled out to Analytics products in July of 2018.

Note that none of these scripts will work out of the box -- you'll need to update the values in brackets with the names of your actual datasets, and you'll most likely also need to replace the names of events and event properties with ones that are appropriate for your app.
