Hi guys, Initially I have the sync mode as

Full refresh | Overwrite

and I changed it to

Incremental | Append

in the UI (I did not choose to reset all streams as I need to keep historical data). However, the connector still get full data other than run an incremental model. Is this a bug?

Can you explain why don't you choose Incremental + Append from the beginning? The first sync will do a full refresh and have complete data. (trying to understand your use case). What version of Airbyte platform are you using and what connectors?
