Bucketized uniqueness score levels. A higher uniqueness score
is a strong signal that the column may contain a unique
identifier like user id. A low value indicates that the column
contains few unique values like booleans or other classifiers.
Values:
UNIQUENESS_SCORE_LEVEL_UNSPECIFIED (0):
Some columns do not have estimated
uniqueness. Possible reasons include having too
few values.
UNIQUENESS_SCORE_LOW (1):
Low uniqueness, possibly a boolean, enum or
similiarly typed column.
UNIQUENESS_SCORE_MEDIUM (2):
Medium uniqueness.
UNIQUENESS_SCORE_HIGH (3):
High uniqueness, possibly a column of free
text or unique identifiers.
