Hi Upayavira, Thank you very much for pointing out the potential design issue
The queries will be determined through a configuration by business users. There will be limited number of queries every day, and will get executed by customers repeatedly. However, business users will change the configurations so that new queries will get generated and also will be limited. The change can be as frequent as daily or weekly. The project is to supporting daily promotional based on fresh index data. Cumulatively, there can be a lot of different queries. If I still want to take the advantage of the filterCache, can I limit the size of the three caches so that the RAM usage will be under control?
