Re: Need an Advice about Memo fields usage in MariaDB.

You can safely store large memos also in LONGTEXT fields. In case of binary data you can store in LONGBLOB fields.

Regarding the speed of retrieval, it is a good practice to exclude these fields in the SQL reading the data and access these fields only when needed.
