Filters

[Paulo_Sousa]

Hi everyone! I work with looker on daily basis in my job and I have a question regarding the dashboards filters and consequently the performance.
I want to know how looker work regarding this filters:

1. Looker load the results from the queries of each tile and then apply the dashboard filters, or;
2. Looker load the results from the queries of each tile applying the filters before return the values?

Thank you in advance!

Hi Paulo, 

In my opinion, filters are applied before returning the results:

After you make a new look with certain data sets and pre-set filters to generate specific charts/tables, more data will process if you try to run again with any additional filters.
