In the "Configure XDCR filtering" section, there is the following statement:
"The filtering expression becomes a part of the key for replication. Therefore, administrators can create multiple replications to the same destination cluster and bucket as long as the filtering expression is different."
This statement came from the original PRD. The requirement and design was changed later, though. In the actual xdcr implementation, the filtering expression is not a part of the key for replication, and multiple replications to the same destination cluster and bucket are not allowed, even if they have different filtering expressions.
The rationale for changing the design is that if there is a need to replicate to the same destination cluster and bucket with different filtering expressions, it can be achieved by creating a single replication with the filter expression being multiple expressions "or"ed together, e.g., filterExpression0|filterExpression1.
The following sample expression would match both "unitedairline" and "marriothotel":
- remove this statement from the doc.
- provide suggestions like the above.
