software.amazon.awssdk.services.firehose.model.OpenXJsonSerDe

All Implemented Interfaces:

Serializable, SdkPojo, ToCopyableBuilder<OpenXJsonSerDe.Builder,OpenXJsonSerDe>

@Generated(value="software.amazon.awssdk:codegen")
public final class OpenXJsonSerDe
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<OpenXJsonSerDe.Builder,OpenXJsonSerDe>

The OpenX SerDe. Used by Kinesis Data Firehose for deserializing data, which means converting it from the JSON format in preparation for serializing it to the Parquet or ORC format. This is one of two deserializers you can choose, depending on which one offers the functionality you need. The other option is the native Hive / HCatalog JsonSerDe.

Method Detail

convertDotsInJsonKeysToUnderscores

public final Boolean convertDotsInJsonKeysToUnderscores()

When set to true, specifies that the names of the keys include dots and that you want Kinesis Data Firehose to replace them with underscores. This is useful because Apache Hive does not allow dots in column names. For example, if the JSON contains a key whose name is "a.b", you can define the column name to be "a_b" when using this option.

The default is false.

Returns:

When set to true, specifies that the names of the keys include dots and that you want Kinesis Data Firehose to replace them with underscores. This is useful because Apache Hive does not allow dots in column names. For example, if the JSON contains a key whose name is "a.b", you can define the column name to be "a_b" when using this option.

The default is false.

caseInsensitive

public final Boolean caseInsensitive()

When set to true, which is the default, Kinesis Data Firehose converts JSON keys to lowercase before deserializing them.

Returns:

When set to true, which is the default, Kinesis Data Firehose converts JSON keys to lowercase before deserializing them.

hasColumnToJsonKeyMappings

public final boolean hasColumnToJsonKeyMappings()

For responses, this returns true if the service returned a value for the ColumnToJsonKeyMappings property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

columnToJsonKeyMappings

public final Map<String,String> columnToJsonKeyMappings()

Maps column names to JSON keys that aren't identical to the column names. This is useful when the JSON contains keys that are Hive keywords. For example, timestamp is a Hive keyword. If you have a JSON key named timestamp, set this parameter to {"ts": "timestamp"} to map this key to a column named ts.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasColumnToJsonKeyMappings() method.

Returns:

Maps column names to JSON keys that aren't identical to the column names. This is useful when the JSON contains keys that are Hive keywords. For example, timestamp is a Hive keyword. If you have a JSON key named timestamp, set this parameter to {"ts": "timestamp"} to map this key to a column named ts.
