java - GAE/Datastore: How to model my data for frequently updated statistics? -


Say I have a unit that has been called user and I want to store statistics about the user, for example how many pages they saw. My dilemma is that I should store a property called "Page-Overview" or a new user called "UserStatistics", which will store all the statistics and store the data in the user unit as it will be linked to a single user.

Because I will need to use many transactions to get the information that related to the institutions that will be otherwise very small, only to read, and needs related, because I think It was probably better to make a new unit for this data to reach (memory) a lot ... if I store these data in the original unit, will it create multiple overhead, or is it B Electricity is no more? If I do a lot of transactions on one unit, will it slow down reading from it?

"itemprop =" text ">

You should store updated data often in a separate unit. Every time you update an entity, you spend writing costs on each indexed property even if these properties do not change.
