monetdb: Online Schema Alters

Question

Does MonetDB support online schema changes? For example adding/changing a column on the fly while the tables are loaded in memory. Many in-memory databases have to restarted to get the schema changes reflected. So, I was wondering if MonetDB took care of this issue.

Answer 1

Yes. MonetDB supports SQL-99 which includes DDL statements (that are immediately reflected in the schema).
