Functions

build_fields_name_type_from_schema

‘Struct’(clickhouse type name is nested) will be converted into some arrays by clickhouse. So we need to make some conversions

contains_decimal 🔒

parse_decimal_accuracy 🔒

Parse (precision, scale) out of a decimal type, or None if it is not a decimal. system.columns renders decimals canonically, so Decimal128(10) arrives as Decimal(38, 10).
