> Improvement on org.apache.derby.impl.jdbc.EmbedBlob#length()
> ------------------------------------------------------------
>
> Key: DERBY-782
> URL: http://issues.apache.org/jira/browse/DERBY-782
> Project: Derby
> Type: Bug
> Components: JDBC
> Reporter: Tomohito Nakayama
> Attachments: testLob4.java
>
> Now, org.apache.derby.impl.jdbc.EmbedBlob#length() method read out whole
> BinaryToRawStream to know exact length.
> On the other hand, BinaryToRawStream have some commented-out inplementation
> of having information for length.
> I think the information of lengh in BinaryToRawStream should be restored to
> be used in .org.apache.derby.impl.jdbc.EmbedBlob#length(), because read out
> whole stream can be expensive processing when streamed information was large.
> There exists a subject that reliability of lengh information in
> BinaryToRawStream is unknown.
