I see. I am actually exploring the possibility to use MVStore to store
networked data (data graphs). Thanks for your input. I will think about
using multiple MVMap's together to store the data. I think I need to at
least have a MVMap to keep all of the data objects which need to be
ta objects will be serialized
again although there is only one object is modified. Can anyone advise the
right way to trigger serialization for only those modified?

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 to
keep a number of
UserData Java objects.
mvs = MVStore.open(".\\test.h2mvs");
mvs.setAutoCommitDelay(10);
data_store =
at org.h2.jdbc.JdbcConnection.(JdbcConnection.java:100)
at org.h2.Driver.connect(Driver.java:69)
at java.sql.DriverManager.getConnection(Unknown Source)
Before the exception occurs, the statement works as expected several
thousand times. Any idea about the cause of the problem?
Any help will
of useing
OffHeapStore over the default storage?
I am confused. Can anyone help?
Thanks in advance!
Michael Wu

Hi,
I didn't notice that MVMap implements ConcurrentMap. Now, I feel confident
to use it. Actually, I think the MVStore library is useful in many use
cases.
Appreciate your help!

Hi,
I am learning to use the MVMap class. I read the source code and found
that the following methods are all synchronized except the get(...) method:
public synchronized V put(K key, V value)
public synchronized void clear()
public synchronized V putIfAbsent(K key, V value)
public synchronized
