Replace #32001. To prevent the context cache from being misused for long-term work (which would result in using invalid cache without awareness), the context cache is designed to exist for a maximum of 10 seconds. This leads to many false reports, especially in the case of slow SQL. This PR increases it to 5 minutes to reduce false reports. 5 minutes is not a very safe value, as a lot of changes may have occurred within that time frame. However, as far as I know, there has not been a case of misuse of context cache discovered so far, so I think 5 minutes should be OK. Please note that after this PR, if warning logs are found again, it should get attention, at that time it can be almost 100% certain that it is a misuse.
