Summary0000004: Stream LOB (large object), BLOB, and CLOB columns
DescriptionBoth CLOBs and BLOBs are read into memory and sent to the database using parametrized statements. This places limits on the size of the LOBs. For example, MySQL will only allow around 32K to be sent as a parameter using this method. Other databases will have similar limits, and reading the data into memory puts a limit on the application memory. We should use InputStream/OutputStream with proper LOB support through JDBC (java.sql.Blob) or Spring (LobHandler).
