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.

getQueryBinding

public String getQueryBinding(ColumnDescriptor column,
 org.apache.kafka.connect.data.Schema schema)

Description copied from interface: Type

Return the SQL string to be used in DML statements for binding this type to SQL.

Specified by:

getQueryBinding in interface Type

Overrides:

getQueryBinding in class AbstractType

Parameters:

column - column descriptor in the table relational model, never null

schema - field schema, never null

Returns:

query parameter argument binding SQL fragment

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

getTypeName

public String getTypeName(DatabaseDialect dialect,
 org.apache.kafka.connect.data.Schema schema,
 boolean key)

Description copied from interface: Type

Return the SQL type name for this type.

Parameters:

dialect - dialect instance, never null

schema - field schema, never null

key - whether the type resolution is for a key field

Returns:

the resolved type to be used in DDL statements
