Subject [jira] Created: (DERBY-3907) Save useful length information for Clobs in store

Save useful length information for Clobs in store
-------------------------------------------------

                 Key: DERBY-3907
                 URL: https://issues.apache.org/jira/browse/DERBY-3907
             Project: Derby
          Issue Type: Improvement
          Components: JDBC, Store
    Affects Versions: 10.5.0.0
            Reporter: Kristian Waagan
            Assignee: Kristian Waagan


The store should save useful length information for Clobs. This allows the length to be found
without decoding the whole data stream.
The following thread raised the issue on what information to store, and also contains some
background information: http://www.nabble.com/Storing-length-information-for-CLOB-on-disk-tp19197535p19197535.html

The information to store, and the exact format of it, is still to be discussed/determined.
Currently two bytes are set aside for length information, which is inadequate.
