default
Parameters
value
Defines the default collation specification of future tables created in the dataset. If a table is created in this dataset without table-level default collation, then the table inherits the dataset default collation, which is applied to the string fields that do not have explicit collation specified. A change to this field affects only tables created afterwards, and does not alter the existing tables. The following values are supported:
'und:ci': undetermined locale, case insensitive.
'': empty string. Default to case-sensitive behavior.
