> 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.
