  - PIG_BLOOMJOIN_STRATEGY
```
public static final java.lang.String PIG_BLOOMJOIN_STRATEGY
```
    Bloom join has two different kind of implementations.
    - map
      In each map, bloom filters are computed on the join keys partitioned by the hashcode of the key with PIG_BLOOMJOIN_NUM_FILTERS number of partitions. Bloom filters from different maps are then combined in the reducer producing one bloom filter per partition. This is efficient and fast if there are smaller number of maps (<10) and the number of distinct keys are not too high. It can be faster with larger number of maps and even with bigger bloom vector sizes, but the amount of data shuffled to the reducer for aggregation becomes huge making it inefficient.
    - reduce
      Join keys are sent from the map to the reducer partitioned by hashcode of the key with PIG_BLOOMJOIN_NUM_FILTERS number of reducers. One bloom filter is then created per partition. This is efficient for larger datasets with lot of maps or very large PIG_BLOOMJOIN_VECTORSIZE_BYTES. In this case size of keys sent to the reducer is smaller than sending bloom filters to reducer for aggregation making it efficient.
    Default value is map.

```
public static final java.lang.String PIG_BLOOMJOIN_NUM_FILTERS
