QUESTION
- I tried to update remote table(dblink) from local database through trigger. I costs around 24990. Table data count nearly 3032965.

The purpose of this test, I am working on a Windows domain, with a development (local) server and a live (remote) server.
The local server has FEDERATED
engine enabled
and the remote server, which stores the actual data but FEDERATED
engine is disabled
.
Both tables (live and federated) have the same definition/schema, and the federated table on the local server has been defined:
...ANSWER
Answered 2017-Feb-22 at 12:49FEDERATED
engine option is not required to be enabled on both servers, in this case, only the local server where the federated table is stored, requires to be enabled.

user requires the PASSWORD
option.
