[jira] Created: (DERBY-872) Fix how to measure performance of lob streaming

Fix how to measure performance of lob streaming
-----------------------------------------------

         Key: DERBY-872
         URL: http://issues.apache.org/jira/browse/DERBY-872
     Project: Derby
        Type: Sub-task
  Components: Performance, Test  
    Reporter: Tomohito Nakayama
 Assigned to: Tomohito Nakayama 


I think the measurement should be done in next 3 points of view at least.

1: Stability of performance.
See the influence of long run.

2: Performance for volume.
See the influence of size of  binary to be streamed.

3: Difference in type of LOB
See the influence of type of LOB, BLOB or CLOB.

Kristian Waagan closed DERBY-872.
---------------------------------

    Resolution: Won't Fix

I'm closing this as won't fix.

The code in question has undergone changes since this issue was logged, and I suggest we create a new issue if we want to investigate the matter further.
Note also that some code for testing this exist in [BC]lobAccessTest.

[jira] Updated: (DERBY-872) Fix how to measure performance of lob streaming

Posted by "Tomohito Nakayama (JIRA)" <de...@db.apache.org>.
     [ http://issues.apache.org/jira/browse/DERBY-872?page=all ]

Tomohito Nakayama updated DERBY-872:
------------------------------------

    Attachment: TestDriver.java
                run.ksh
                file_500k.txt

I revised ClobTest program contributed by Sunitha so that we can test blob not only clob , which was tested originally.
