Subject [jira] Commented: (UIMA-1196) Add support for binary serialization and deserialization in Uima AS
Date Wed, 08 Oct 2008 17:11:44 GMT

    [ https://issues.apache.org/jira/browse/UIMA-1196?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12637988#action_12637988

Jerry Cwiklik commented on UIMA-1196:

While addressing binary serialization I need to determine the default serialization strategy
for CASes destined for remote delegate. Binary serialization, although much faster than XMI
has one serious problem. It requires that all uima AS services use a common type system. Also
merge is not yet supported for binary serialization as well as delta CAS. It seems that XMI,
albeit slower, is a better choice as a default serialization strategy.  Comments?

> Uima AS needs faster serialization and deserialization logic for CASes destined for remote
delegates. XMI serialization introduces a significant overhead. Modify Uima AS Serializer
to use existing binary Serializer and Deserializer from Uima Core. Modify code that creates
outbound jms messages to carry binary cargo instead of a String. Modify inbound code to recognize
binary cargo and deserialize CAS using binary serialization.
