Steve Lawrence updated DAFFODIL-1735:
-------------------------------------
Fix Version/s: 2.5.0
> BLOB/CLOB - large object handles
> --------------------------------
>
> Key: DAFFODIL-1735
> URL: https://issues.apache.org/jira/browse/DAFFODIL-1735
> Project: Daffodil
> Issue Type: New Feature
> Components: API, Back End, DFDL Language, Front End
> Reporter: Michael Beckerle
> Assignee: Steve Lawrence
> Priority: Major
> Fix For: 2.5.0
>
>
> Binary large object, and character large object (aka BLOB/CLOB) support is
> needed.
> Rather than transforming a large binary object into hexBinary or string,
> instead one annotates the DFDL schema to specify that a BLOB/CLOB handle is
> preferred. The Infoset then contains not the data, but a token/object that
> can be fed to an "open" API to access a stream of the data. The token/object
> is a small sized thing. This allows data formats like JPEG 2000 where
> payloads are often gigabytes.
> Note: implementing this requires revising our ByteBufferDataInputStream layer
> into one that does not require the input data to fit in memory.
> See article on Wiki about large objects:
