Uses of JoinStrategy in org.apache.crunch.lib.join

Classes in org.apache.crunch.lib.join that implement JoinStrategy
 class BloomFilterJoinStrategy<K,U,V>
          Join strategy that uses a Bloom filter that is trained on the keys of the left-side table to filter the key/value pairs of the right-side table before sending through the shuffle and reduce phase.
 class DefaultJoinStrategy<K,U,V>
          Default join strategy that simply sends all data through the map, shuffle, and reduce phase.
 class MapsideJoinStrategy<K,U,V>
          Utility for doing map side joins on a common key between two PTables.
 class ShardedJoinStrategy<K,U,V>
          JoinStrategy that splits the key space up into shards.

Constructors in org.apache.crunch.lib.join with parameters of type JoinStrategy
BloomFilterJoinStrategy(int numElements, float falsePositiveRate, JoinStrategy<K,U,V> delegateJoinStrategy)
          Instantiate with the expected number of unique keys in the left table, and the acceptable false positive rate for the Bloom filter, and an underlying join strategy to delegate to.
