I noticed at one point my cache was almost 10GB. I think I had been running the same OS install for over a year at that point so it was not "huge" for the time period or for the lifetime of OS images (usually no more than 3 years). So I am wondering now, is there anything built in and turned on by default to prevent the Tableau Desktop/Reader cache from becoming very large? e.g. might old or infrequently-used entries be purged when a size threshold is exceeded?
I see I can manually clear it from Clearing the Tableau Desktop Query Cache | Tableau Software and I think this is fine for developers (Tableau Desktop) but I am wondering if I will ever have to message to my users (Tableau Reader) they could need to do this occasionally. I see we can also disable the cache from Disabling External Caching in Tableau Desktop and Tableau Reader | Tableau Software but this is also not an out-of-the-box default.
My concerns stem around long-term eventual behavior when workbook consumers have opened lots of workbooks with different data connections and whether we need to recommend occasional cache clearing. I would much rather the Reader/Desktop software maintained the cache itself rather than making it our/our users' problem.
Probably if nothing is in place already (I can't seem to find it documented) I would submit a "community idea" to have a cache clear button in the menu or to simply limit it to 5GB or something.
Hey Jonathan,
You are correct in that you should submit an Idea as the only solutions I've seen has been to script the cleanup.
