When the Connect CDC Director maps a source table to a same-named target table, it also associates individual source table columns with same-named target table columns. You then select which of these column pairings you want to include in your data distribution, which additional column pairings you want to arrange, and what type of data transformation, if any, you want to assign to each column pairing.
Note: You can also define a rule for selecting which rows are sent to some receiving tables and not to others. This conditional row distribution is described in Conditionally distributing data .
