UDT (User Defined Types) schema mismatch #128

Closed ahmedosama94 closed 6 years ago

ahmedosama94 commented 7 years ago

When using a user defined type, the first time the table is created, express-cassandra handles it smoothly, but when the table is already created there is always an apollo.model.tablecreation.schemamismatch error thrown, and then it attempts to drop and recreate the column.

Gives this message on each run (migration set to alter), if it is helpful: model schema for table "table" has new incompatible type for field "field"

@masumsoft I found the issue to be using FROZEN in uppercase in the set's typeDef, solved the issue by changing ({ type: "set", typeDef: "<FROZEN>" }) to ({ type: "set", typeDef: "<frozen>" }), so the problem turns out to be case insensitivity on schema load on and case sensitivity on schema matching. I hope this is useful.

@ahmedosama94 thanks for the update, though I didn't have much time to fix this issue yet, your findings would definitely help dig out the problem faster. Current version 2 milestone has a lot of new things in progress and I'm hopeful it would be resolved soon with the 2.0.0 release. For now use lowercased definitions.
