Read and writing data temporarily

Hello, is there a way to write/read data temporarily? I would like to test a flow and get average values over time but I do not need to store or keep the data. Would it be possible to use sqlite node and set the database name to memory?
Note : Setting the database name to :memory: will create a non-persistant in memory database.
Thank you for any suggestions!
