Insight makes it easy to ask questions of ALL of your clinical and operational data and visualize answers via interactive reports and dashboards. The idea is simple, but the results are powerful: ask your questions, choose your visualizations, then return often for updated, interactive results that link you to all of the underlying data.

Downloading Rules and large Dataset- Technical advice


Today I tried to download all my rules (680 rules) in xml, and I had a "504 Gateway Timeout error".
Are you aware of this error ? I'm using nginx as a reverse proxy on OC 3.12.
I googled this error and I finally changed my parameters in my nginx.conf file and increased my timeout from 120 to 180 for proxy_connect_timeout and proxy_read_timeout.
It seems to work now but I'm not sure if it is the appropriate solution and the right thing to do.
Could you please tell me what you think ?

My main concern is about dataset extraction. My study is very large (many subjects, follow-up, tables...) and a job runs every night to perform the extraction. For the moment it runs fine but it begins to take a large amount of time to perform the extration.
The extraction will get bigger and bigger and with time I'm afraid that it won't work anymore and I can't afford to be stuck.
Do you know which parameters I should change to optimize the extraction or to be sure that even if it takes a long time (during the night so it's ok), it is always a success ?

Thank you !
