Examples of PartitionKey

com.bazaarvoice.ostrich.partition.PartitionKey

A key for retrieving partitions from a {@link Dataset}.

A {@code PartitionKey} is a ordered sequence of values corresponding to the{@link FieldPartitioner}s in a {@link PartitionStrategy}. A {@link PartitionKey} may be obtained using{@link PartitionStrategy#partitionKey(Object)} or{@link PartitionStrategy#partitionKeyForEntity(Object)}.

Implementations of {@link PartitionKey} are typically not thread-safe; that is,the behavior when accessing a single instance from multiple threads is undefined.

This interface represents a partition key. A partition key consists of a table and values that make up the partition key. An instance of this interface can be used to specify the partition key used when starting a transaction.
org.kitesdk.data.spi.PartitionKey

A key for retrieving partitions from a {@link org.kitesdk.data.Dataset}.

A {@code PartitionKey} is an ordered sequence of values corresponding to the{@link org.kitesdk.data.spi.FieldPartitioner}s in a {@link org.kitesdk.data.PartitionStrategy}. You can obtain a {@link PartitionKey} using{@link PartitionKey#partitionKeyForEntity(org.kitesdk.data.PartitionStrategy,Object,EntityAccessor,PartitionKey)}.

Implementations of {@link PartitionKey} are typically not thread-safe; that is, the behavior when accessing a single instance from multiple threads is undefined.
