Thank you very much for the tips. I'll move to a service. I made a mistake in the calculus. The update is about 30 rows per second, in average. The max update will be 300 per second, but rarely occurs. The idea for the index is great. Every row is an object. Em 14/02/2014 02:05, "Sander Elias" <[email protected]> escreveu:
