Is it safe to cache Gmail API message results?

Question

I am iterating over a Gmail account with many thousands of messages. To save resources I am caching the results of users.messages.get. Is it safe to cache this data indefinitely? Will the data it returns ever change? I assume that it will not but so far I am unable to find anything definitive in the docs or otherwise to confirm this.

Answer 1

It can change - though it might not necessarily change in a way that you care about.

The API itself lets you change the labels on a Message and delete messages.
