Atualização 1:
Após adicionar o índice de várias colunas na tabela tms_door_record_raw (KEY card_no_record_time( card_no, record_time)) A execução do sql caiu de 11 minutos para 3,2 segundos
Execute o sql de explicação novamente. A chave da tabela de junção para drmudou de (card_no) para (card_no, record_time) também na coluna extra que está sendo exibidaUsing where; Using index

Remova o GROUP BY.
Se você tiver duplicatas (lógicamente válidas), remova-as no estágio inicial.

tms_door_record_rawtabela ter vários registros com o cartão único no. Por exemplo, o cartão 0001 possui poucos registros de entrada / saída em um dia; portanto, ele mostrará vários registros onde eu só preciso se o cartão tiver um registro nesse dia.
