Package io.debezium.connector.mysql.converters

Class TinyIntOneToBooleanConverter

java.lang.Object

io.debezium.connector.mysql.converters.TinyIntOneToBooleanConverter

All Implemented Interfaces:

io.debezium.spi.converter.CustomConverter<org.apache.kafka.connect.data.SchemaBuilder,io.debezium.spi.converter.RelationalColumn>

public class TinyIntOneToBooleanConverter
extends Object
implements io.debezium.spi.converter.CustomConverter<org.apache.kafka.connect.data.SchemaBuilder,io.debezium.spi.converter.RelationalColumn>

MySQL reports BOOLEAN values as TINYINT(1) in snapshot phase even as a result of DESCRIBE CREATE TABLE. This custom converter allows user to handle all TINYINT(1) fields as BOOLEAN or provide a set of regexes to match only subset of tables/columns.
