Consider the following rules and guidelines when you create mapping and mapping tasks:
•If the input value to the Couchbase string contains more than 255 characters, the task fails.
•If you specify the host name, port number, user name, and password of the Couchbase server in the Additional Connection Properties, the values specified in the Additional Connection Properties takes precedence.
•When you read data from or write data to a Couchbase virtual table, you must not specify 1 as the value of the QueryMode parameter in the additional connection properties.
