Jingsong Lee updated FLINK-28017:
---------------------------------
    Description: 
Specifies the table store distribution policy. Data is assigned to each bucket 
according to the hash value of bucket-key.
 * It is primary key when table has primary key. The user can specify a bucket 
key, it should be part of primary keys.
 * It is all fields when table has no primary key.

If there are filter conditions for specific fields, reasonable settings can 
give a big performance boost to the table, but care needs to be taken to avoid 
data skewing.
