I imagine I may lack important details, so please don’t hesitate to ask for more info.
I have a database that is approximately 130 GB large. One of the tables is “c_feature”, see screenshot below.
I ran the following seemingly simple query, explain analyze select min(start_time) from c_feature where end_time is null and start_time < ‘2018-01-27 14:25:30’;
The results are below.
What does this suggest? Why does the query take 2 hours?
Any help will be greatly appreciated.
