We have added a probe in Bug 1941935 to measure purge rate of cache data.
To get sufficient data, we need to let this probe data from 1 release for our base measurement.
Hence, we can increase the metadata size limit to 1 MB for our nightly users and increase it in the next cycle for our release users.
