Maximum data size limit for CLOB and BLOB data types supported by ML Engine is 10 MB. When a CLOB or BLOB column with more than 10 MB of data is transferred from Advanced SQL Engine to ML Engine, QueryGrid truncates the data to 10 MB. Likewise, when data generated by ML Engine exceeds 10 MB in a column, QueryGrid truncates it to 10 MB.
