Hi there,

[primary key handling]

Thanks for that information.

I see in the demo code that you use make_table_stateful on the tables,
which adds a column
'state' to what I understand to be the main table (not the revision table).

What is this doing? Presumably it can't lead to the situation where I
have two records with the
same id but in a different state. Is this in practice only used to
track the deleted state?

Regards,

Martijn
