You are looking for a detailed log of all of the schema changes that Fivetran makes in your destination.
Fivetran captures all the changes we make to your destination schemas and tables as events in the Fivetran Log Connector.
You can query the data to find the schema and table changes, and when the change occurred:
Make sure that the Fivetran Log Connector is running.
LOGtable for the following events:
create_schema: Schema created in destination
create_table: Table created in destination
drop_table: Table dropped from destination
alter_table: Table columns added to, modified in or dropped from destination table
(Optional) Create a view that tracks all of these events to identify schema changes.
