>
> Currently the stream-related APIs for CLOBs and BLOBs are not supported in
> JDBC drivers (both client and thin). Say the following ones:
> * Blob.setBinaryStream
> * PreparedStatement.setBlob(int parameterIndex, InputStream inputStream)
> It makes the creation of BLOBs and CLOBs inefficient (memory wise) for large
> data.
> The whole data should be preloaded to RAM before the LOB creation.
> After that several copies of the input memory blocks are created just to pass
> it to prepared statement etc. It should be optimized to reduce the heap
> memory requirements.
