| Re: [eclipselink-users] LOB streaming |
Please log an enhancement request for this. You might be able to map the blob using a Converter in EclipseLink, and convert the JDBC Blob to a Reader of some sort. You will also need to ensure you use exclusive connections on your EclipseLink session to hold the JDBC connection for the duration of the EntityManager. But, given the size of the blobs, processing them directly in JDBC may be the best way to go. stefan.reinhold wrote: > > > Hi there, > > I've got large BLOBs (around 100 MB) that I don't want to hold in memory > completely.
