Class PartitionSpec
- All Implemented Interfaces:
Serializable,SdkPojo,ToCopyableBuilder<PartitionSpec.Builder,PartitionSpec>
Represents how to produce partition data for a table. Partition data is produced by transforming columns in a table.
Each column transform is represented by a named PartitionField.
Here is an example of the schema in JSON.
"partitionSpec": { "identity": [ {"sourceName": "column1"}, {"sourceName": "column2"}, {"sourceName": "column3"} ] }

Method Details
-
hasIdentity
public final boolean hasIdentity()For responses, this returns true if the service returned a value for the Identity property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()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. -
identity
List of identity transforms that performs an identity transformation. The transform takes the source value, and does not modify it. Result type is the source type.
Amazon Data Firehose is in preview release and is subject to change.
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
hasIdentity()method.- Returns:
- List of identity transforms that
performs an identity transformation. The transform takes the source value, and does not modify it. Result
type is the source type.

equalsBySdkFields
Description copied from interface:SdkPojoIndicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in anSdkPojoclass, and is generated based on a service model.If an
SdkPojoclass does not have any inherited fields,equalsBySdkFieldsandequalsare essentially the same.- Specified by:

obj- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
