[jira] [Updated] (IGNITE-12543) When put List>,
the data was increased much larger.
[ https://issues.apache.org/jira/browse/IGNITE-12543?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
LEE PYUNG BEOM updated IGNITE-12543:
------------------------------------
Description:
When using Java Thin Client with Ignite 2.6,
When I put data in the form List<List<SomeObject>>,
the size of the original 200KB data was increased to 50MB when inquired by Ignite servers.
On the Heap Dump, the list element was repeatedly accumulated, increasing the data size.
When I checked main.java.org.apacheignite.internal.binary.BinaryWriterExImpl.java doWriteBinaryObject method,
{code:java}
// main.java.org.apacheignite.internal.binary.BinaryWriterExImpl.java
public void doWriteBinaryObject(@Nullable BinaryObjectImpl po) {
if (po == null)
out.writeByte(GridBinaryMarshaller.NULL);
else {
byte[] poArr = po.array();
out.unsafeEnsure(1 + 4 + poArr.length +4);
out.unsafeWriteByte(GridBinaryMarshaller.BINARY_OBJ);
out.unsafeWriteInt(poArr.length);
out.writeByteArray(poArr);
out.unsafeWriteInt(po.start());
}
}
{code}
The size of the inside list is increasing by repeating the number of inner lists, which can lead to memory errors depending on the capacity of the object and the number of lists.

On the Heap Dump, the list element was repeatedly accumulated, increasing the data size.
Under network monitoring, normal size was measured during transmission from the client to the server.
Do you have a history of reported issues?
