Integrate support for streaming data types as extension to byte[] buffers into
Cayenne
--------------------------------------------------------------------------------------
Key: CAY-1664
URL: https://issues.apache.org/jira/browse/CAY-1664
Project: Cayenne
Issue Type: Improvement
Components: Database integration
Affects Versions: Short term future
Reporter: Daniel Scheibe
Priority: Minor
Fix For: Undefined future
Whenever BLOB data is accessed it has to happen through byte[] buffers at the
moment. It would be great to gain the advantage of using streams to store BLOB
data to the underlying database. The JDBC API supports streaming data types and
certain JDBC Drivers implement it in a proper way already. Another benefit
would be to handle binary and object data together inside a real transaction.
Comments:
- MYSQL doesn't support this right know (see max_packet_size limit and the JDBC
Driver simply reads the whole stream data into a ByteBufferStream before
transfer so theres no advantage)
- Microsoft SQL Server 2080 offers a FileStream data type which allows to
handle large binary data via the Database Server so this would be a great
benefit)
