Hi, I was wondering if/when a subset of cols is specified then does that mean it will be possible for the table to be replicated to a *smaller* table at the subscriber side?
e.g Can a table with 7 cols replicated to a table with 2 cols?
I thought maybe that should be possible, but the expected behaviour for that scenario was not very clear to me from the thread/patch comments. And the new TAP test uses the tab1 table created exactly the same for pub/sub, so I couldn't tell from the test code either.
Currently, this capability is not included in the patch. If the table on the subscriber
server has lesser attributes than that on the publisher server, it throws an error at the
time of CREATE SUBSCRIPTION.
About having such a functionality, I don't immediately see any issue with it as long
as we make sure replica identity columns are always present on both instances.
However, need to carefully consider situations in which a server subscribes to multiple
publications, each publishing a different subset of columns of a table.
