Is there a way to create a caching table, some sort of a materialized view, such that upon selecting from that table, its data is validated/invalidated?
But to elaborate the point: say I have some table data_table. Can I rewrite all my queries which access data_table to read from some autocache_data_table, but have nothing changed in the query itself? No caveats, no additional WHEREs, and still have that autocache_data_table provide with the correct data, dynamically updated by some rule of our choice?
And: no crontab, no event scheduler, and no funny triggers on data_table? In such way that invalidation/revalidation occurs upon SELECT?
