What would be an appropriate / suitable database sans Oracle that would be suitable for the following conditions?
data mining includes but does not limit to the following: a. clicking on links b. capture geolocation data, platform details c. user behaviours
there will be a foreseen exponential surge of data being captured as more apps / sites being deployed
for now, there are on average 60,000 ~ 80,000 data being captured every 15 minutes for 2 main sites / apps
In the near future, we are also planning to release all these data to the various parties involved where they can use it for their own apps / sites.
As of now, we are using mySQL but we found that it becomes very costly as we started to scale up. As such, any advice would be good as a starting point.
