check_delay_period
Obsolete setting, does nothing.check_sample_column_is_correct
Enables the check at table creation, that the data type of a column for s ampling or sampling expression is correct. The data type must be one of unsigned integer types:UInt8, UInt16,
UInt32, UInt64.
Possible values:
true— The check is enabled.false— The check is disabled at table creation.
true.
By default, the ClickHouse server checks at table creation the data type of
a column for sampling or sampling expression. If you already have tables with
incorrect sampling expression and do not want the server to raise an exception
during startup, set check_sample_column_is_correct to false.
