Hello learner always,
I'm not well versed into Cache and Server, however I'm sure how community could help you on that matter.
Does anyone knows why the why would total_net_output_bytes is reported as '0'?
Along the same lines i see the following parameter set to true, i.e. disabled, what does this parameter mean:
Another parameter that is confusing:
Whats the difference between external_abstract_query_cache_disable and external_native_query_cache_disable

Glad you're having fun with the YAML files! However, the settings which aren't documented....well, they aren't documented. You generally won't get much additional help with them here because we frankly don't want you messing with them and potentially breaking something
You should also keep in mind that some of the settings you see may not even apply to your "On-prem" Tableau Server - some of them are used for Tableau Online or Public.
SO, if you're really curious about these, my advice would be to change them (on a QA server) and see what happens! 60% of the time, you probably won't be able to detect a difference. 20% of the time ou'll break something, the other 20% might yield some interesting results.
FYI, the difference between the abstract and native cache is the TYPE of data they hold. The abstract cache is a more generalized cache that can often be re-used many times to answer slightly different questions. Entries in the Native cache are tried directly to a specific querystring & connect string combination.
Understood, do these settings impact "on-perm" tableau server or are they for online only.
Don't know - I'd never be interested in these settings because turning the cache off would be bad for all-around performance. I'm sure there's a reason why they're in there, but I don't know it
