Hi,
I am trying MVStore for storing & managing a large number of Java
serializable objects.
I develop a simple Java program. It uses a HashMap<String, UserData> to
keep a number of
UserData Java objects.
mvs = MVStore.open(".\\test.h2mvs");
mvs.setAutoCommitDelay(10);
data_store = mvs.openMap(test_hint);
user_accounts = new HashMap<String, UserData>();
for (int i=0; i<10; i++) {
String id = "cust_" + (i+1);
user_accounts.put(id, new UserData(id));
}
data_store.put("user_accounts", user_accounts);
...
mvs.close();
I found that all of the UserData objects contained in the user_accounts
HashMap are
serialized to the file if the following code
data_store.put("user_accounts", user_accounts);
is executed. I have two questions (needs):
1) How to trigger the serialization to happen when one of serveral UserData
objects
in the user_accounts HashMap are modified?
2) How to serialize only those UserData objects in the user_accounts
HashMap modified?
Any help will be highly appreciated!
