When doing memory analysis in Java, TreeMap is found inside the object -


I'm new to memory analysis in Java.

I have performance report message , which is the cost of 25k memory to me:

Enter image details here

When I look at the object in memory analysis in Eclipse, then I think inside a TreeMap The structure, which eats the most size of the whole object.

This is my question:

  1. Where does the treemark come from? I do not have the TreeMap structure in the class definition.

  2. I would like to reduce the size of the object as much as possible. Any possible way to do this?

    1) It looks like this quickfix.fix42. ExecutionReport is inside the object .. ??

    Update: This is actually inside quickfix.fix42.ExecutionReport , by which the succession increases the quickfix.FieldMap class, in which two TreeMaps

    2) Remove the performance report from your exception and archive the field you need it.

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...
