If question only about this, then my opinion that it must be fine-grained at a column level. But there should be a possibility to set an implementation for context wide. It will cover the case where you use mixed scheme: all tables have one generator, except several that have per table generators. You specify context-wide implementation per database generator, and in ModelBuilder you specify generators for these exceptional tables.

Re: [Firebird-net-provider] Migrations
Hi all Jiri asked me to kick in because we have two products. One with one generator per column, one with one generator per database. Pro's of generator per table are You have the feeling of a sequence. There shouldn't be a gap, you can do "math" on it.This is how other db's have it since DBase. Pro's of one generator per database... I have an orm that more or less only works fine if you assign the PK on creation of the object. Per instance I can now do a single trip to the db and do gen_id(pk, 1000) and create myself a nice pool of unique ids that I can design without additional roundtrips to the db. It really removes all sense from PK's and that is how I think it should be. There are huge gaps and that is perfectly explainable. All records inside the db have a unique key. If you ever need to synchronize two db's... you can start the one on 1.000.000.000, second on 2.000.000.000, ... whatever You don't need to manage 5 billion generators. Imho opinion I would never go back to generator per table. I discover every month new goodies that make my choice for 1 generator awesome. But I do think... for the common sense and feeling... one table, one generator makes most sense... even when it sucks. Hopes this solves your debate.

Re: [Firebird-net-provider] Migrations
Ok. For now we had such issues: 1. Long names of tables causes foreign key script creation fail with error Name exceeded implementation limitation. This caused by 31 characters limitation to almost anything not only FK. We crutched this with hashing names with base64 convert. Ugly but works. 2. Second it is drop from support databases with pages less than 16384 because of another impl. limitation for max string field length. This breaks creating MigrationHistory table. We didn't fixed this, because started using separate database. But in near future our previous database would also need to have migrations. I think this can be crutched to use blob field only for Model field of this table. 3. Issue with sequence generators. Maybe you remember discussion about this on github. Looks like I've found good place to configurate particular field. It is in OnModelCreating Properties().Configure(x=x.AddAnotation()) for property.

1. I've used hashes from names to avoid dictionaries for mapping name-guid. 2. I think it was about Model field. More precise error I'll tell tomorrow when PC will be available. I don't want to constraint page size, because changing page size for existing databases is done only via backup-restore AFAIK. In case of several GB dbs it's not an option. 3. Yes. Default behavior maybe several pre defined and possibility to provide custom. 4. One more issue I remembered. Dbs created with Initial migration and via CreateDatabaseIfNotExists have different underlying scheme in part of names.
