Currently I have running 3 (three) desktop applications which consult 1 (one) time per minute a database to know if there are new features in it. The database is hosted in a website hosting (I have the DB of the website itself and another DB for this purpose)
The database engine is MySQL
My question is, will I be saturating the DB with 3 queries per minute? (It's just a SELECT). What other alternative do I have to polling to know if there are new features in the database?
