Which Tool to use for generating a Schema Diff?

Are there any tools recommended to produce a good schema diff between two MemSQL schemas? For example, I have an older version of a memsql schema and a newer version of a memsql schema, and I’d like to have the diff generate DDL which will ‘upgrade’ the schema on old to match the schema on new with the necessary adds/drops/alters/etc.

Several comments have been deleted. All were relevant. Why the deletions?

your good information and interesting question but i am not idea.

Do you recall which comments you saw were deleted? Were those comments yours? I want to look into this to see what I can find.
