Steven Hawkins created TEIID-3157: ------------------------------------- Summary: Allow streaming without an intermediate copy Key: TEIID-3157 URL: https://issues.jboss.org/browse/TEIID-3157 Project: Teiid Issue Type: Enhancement Components: JDBC Driver Reporter: Haifen Bi Assignee: Steven Hawkins Fix For: 8.9 We have quite large size of data file (>10G) that needs to be sent back to server from client. Following is JDBC client code: void writeData(int id) { String sql = "UPDATE DataSet set data = ? WHERE id = ?"; try { InputStream is = new FileInputStream("c:\\temp\\data"); this.ps = connection.prepareStatement(sql); this.ps.setBlob(1, is); this.ps.setInt(2, id); ps.executeUpdate(); } catch (Exception e) { .. } } Teiid throws "lob too big" error when executing above code: 10:01:18,801 WARN [org.teiid.TRANSPORT] (New I/O worker #1) TEIID40113 Unhandled exception, aborting operation: java.io.StreamCorruptedException: lob too big: 429496456065534 (max: 4294967296) at org.teiid.transport.ObjectDecoder.decode(ObjectDecoder.java:142) [teiid-runtime-8.7.0.Final.jar:8.7.0.Final] at org.jboss.netty.handler.codec.frame.FrameDecoder.callDecode(FrameDecoder.java:425) [netty-3.6.2.Final.jar:] at org.jboss.netty.handler.codec.frame.FrameDecoder.messageReceived(FrameDecoder.java:310) [netty-3.6.2.Final.jar:] at org.jboss.netty.channel.Channels.fireMessageReceived(Channels.java:268) [netty-3.6.2.Final.jar:] at org.jboss.netty.channel.Channels.fireMessageReceived(Channels.java:255) [netty-3.6.2.Final.jar:] at org.jboss.netty.channel.socket.nio.NioWorker.read(NioWorker.java:88) [netty-3.6.2.Final.jar:] It seemed teiid has stream data size limit (4G?). With this limitation, it is not possible to send more than 4G of stream data in Teiid. -- This message was sent by Atlassian JIRA (v6.3.1#6329)
