[jboss-jira] [JBoss JIRA] Commented: (JGRP-653) Streaming API for large messages

[ http://jira.jboss.com/jira/browse/JGRP-653?page=comments#action_12419585 ] Manik Surtani commented on JGRP-653: ------------------------------------ That makes sense in the case of a DVD which is treated as a byte array. In the case of streaming a large Object (for example, a large XML DOM tree, but any arbitrary Object applies), it is a bit different: Without using streams, this is what would happen, for example in the JGroups Marshaller: Sender: 1. Write entire Object to byte array using an ObjectOutputStream and a ByteArrayOutputStream 2. Return byte array for transmission // already we are consuming twice the memory space of the Object! Receiver: 1. Retrieve entire byte array 2. Deserialize object from byte array using an ObjectInputStream and a ByteArrayInputStream // again, consuming twice as much memory Using a JGroups streaming API, we could potentially do something like: Sender: 1. Write Object using an ObjectOutputStream to wrap a JGroupsOutputStream. Receiver: 1. Deserialize Object using an ObjectInputStream to wrap a JGroupsInputStream The JGroupsInput/OutputStreams could have a small internal byte buffer (perhaps based on message payload size) so as soon as enough bytes have been read the message can be transmitted, received and deserialized. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
