The dbtransoform filter can be used to apply standard Java Regex expressions to rename databases and/or tables between source and target.

Up to 4 from/to regex patterns can be provided. By default the transofrmation will be applied to Database Schema names. To use the transofrm for Table Names, specify the transformTables=true option.

The filter will only transform database or tables, not a mix of the two. For more advanced transofrmation you may want to consider the rename filter instead

The filter only wors with ROW events. Statement based transofrmation are not supported with this filter.
