java - Out of Memory Exception while loading data into List -


I'm trying to generate a heatmap on a googlemap, about 2 million digits (latitude and longitude). My thoughts are to read the numbers from the table, and they have to give it to the Google API in the list. The problem is, loading the 2 million points in the list causes a memory error in EJB. The following is the line that gives me an error. 

  list & gt; Earthquake & gt; Earthquake risklist = em.createNativeQuery ("Select as geomette (geomia), in the form of risks, Earthcomcers E from Eidcom", Earthquarkarsk. Class). GetResultList ();   
 What options can be applied to read and load points in the map? I have glassfish 3.2.2, JDK 1.7, JSF 2.2, ezb.   
 
 
 You can see:  
 In addition, Have you thought about implementing your own? After this you can recover the required data on demand when the itater completes the next stage.  
 Another option would be to split your dataset - like you want to score on the page.

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
