=== Boolean types
Oracle does not natively have support for a `BOOLEAN` data type; however,
it is common practice to use other data types with certain semantics to simulate the concept of a logical `BOOLEAN` data type.
The operator can configure the out-of-the-box `NumberOneToBooleanConverter` custom converter that would either map all `NUMBER(1)` columns to a `BOOLEAN` or if the `selector` parameter is set,
then a subset of columns could be enumerated using a comma-separated list of regular expressions.
Following is an example configuration:

converters=boolean
boolean.type=io.debezium.connector.oracle.converters.NumberOneToBooleanConverter
boolean.selector=.*MYTABLE.FLAG,.*.IS_ARCHIVED

The setting of the Oracle connector configuration property, `decimal.handling.mode` determines how the connector maps decimal types. The setting of the Oracle connector configuration property, `decimal.handling.mode` determines how the connector maps decimal types.
