storages::clickhouse::io::columns::MismatchedEndiannessUuidColumn Class Referencefinal

#include <userver/storages/clickhouse/io/columns/uuid_column.hpp>

Detailed Description

Legacy broken ClickHouse UUID column representation.

Warning
This implementation is broken in a way that uuids endianness is mismatched: uuid "30eec7b3-0b5c-451e-8976-98f62b4c4448" will be stored as uuid "1e455c0b-b3c7-ee30-4844-4c2bf6987689" in ClickHouse (notice that each of 8 hex bytes group is bytewise reversed).

Requires both writes and reads to be performed via userver to work.
