EclipseLink JPA With PostgreSQL
There is quite alot of functionality that can be overridden through subclassing our various database platforms. What I need is large files not fit in RAM to be part of a transaction when writing data. When it comes to handelign LOBs I need something like this: I am still looking in to the best way to get around that issue.
I chose to have one database and multiples schemas instead of having multiples databases and one schema per database.
There are a couple of parts that are a little hacky, so we still should add an enhancement request to make this work more smoothly. I want to access schema 00 or 01 in testdb database. Some key points about the postbresql I probably could change schema via native SQL directly but is there a way to bind schema to persistence unit?
This same question was asked and answered here: In reply to this post by Andreas Joseph Krogh. I ran into something similar with HSQL. Are there any examples around using PG with Blobs, using streams not byte? Sign up or log in Sign up using Google.

JPA – EclipseLink – How to change default schema You can override the schema for the entire persistence unit using an orm. Do you keep the stream open for a long period of time?
For my model I went with a byte property since Blob is an interface. I need be able to call myBinaryProperty.
It subclasses BigInteger to get around some of the restrictions we have about what can be mapped as a Basic. On Jun 24,at 4: You can override the schema for the entire persistence unit using an orm. Sign up using Email and Password.
Post as a guest Name. Currently, by default, when reading EclipseLink will read all the data in the BLOB by default – the reason is because after we are done with the connection, we will not have that option anymore. Search everywhere only in this topic. Which in HSQL’s case has pretty big implications.
