If your data is 200 000 characters or larger per item, then you should use CLOB. There is also a database option to translate LONGVARCHAR to CLOB, but it's easier to specify clob directly. For example: CREATE TABLE T (ID INT PRIMARY KEY, DATA CLOB(16M) The above means a clob up to 16 MB can be stored. It allocates space only according to the size of the actual data. For example if a data item is 128 000 characters, it assigns 256 KB. You could use LONGVARCHAR for your data and it also allocates space as needed , but it will slow down your app. The latest snapshot jars for version 2.3.0 also support clob compression for storage. The final version will be released next month.
