Andrey Gura commented on IGNITE-5203:
-------------------------------------
Vladimir,
in current design BLOB is just a wrapper for byte array that can be stored as
field of some object. Only simplest operations are supported. It is mostly
designed for reading data from byte arrays. {{ResultSet.getBlob()}} method just
delegates call to {{ResultSet.getBytes()}} method. {{ResultSet.updateBlob()}}
and {{PreparedStatement.setBlob()}} methods are not supported yet.
> JDBC driver should support BLOB fields
