All Implemented Interfaces:

public abstract class AbstractConnectMapType
extends AbstractConnectSchemaType

An implementation of Type for MAP schema types. This is created an abstract implementation as its expected that each dialect will create its own implementation as the logic to handle map-based schema types differs by dialect.

Method Details

getRegistrationKeys

public String[] getRegistrationKeys()

Description copied from interface: Type

Returns the names that this type will be mapped as.

For example, when creating a custom mapping for io.debezium.data.Bits, a type could be registered using the LOGICAL_NAME of the schema if the type is to be used when a schema name is identified; otherwise it could be registered as the raw column type when column type propagation is enabled.

getDefaultValueBinding

public String getDefaultValueBinding(DatabaseDialect dialect,
 org.apache.kafka.connect.data.Schema schema,
 Object value)

Description copied from interface: Type

Resolve the default value clause value.

Specified by:

getDefaultValueBinding in interface Type

Overrides:

getDefaultValueBinding in class AbstractType

Parameters:

dialect - dialect instance, never null

schema - field schema, never null

value - the default value, should not be null

Returns:

the formatted default value for the SQL statement as a string

mapToJsonString

protected String mapToJsonString(Object value)
