Nesta página, descrevemos como gerenciar o número de tabelas temporárias. Esse recommender é chamado de Reconfigurar configurações da tabela temporária.
Todos os dias, esse recomendador analisa o número de tabelas temporárias
criadas no disco em comparação com o número total de tabelas temporárias. Se o
número de tabelas temporárias criadas no disco for superior a 20% do número
total de tabelas, este recomendador aconselha você a seguir um destes procedimentos:
Aumente o valor da flag tmp_table_size, max_heap_table_size ou de ambas.
Se os valores de max_heap_tmp_table_size e tmp_table_size não forem iguais,
aumente o valor menor para corresponder ao maior.
Se os valores de max_heap_tmp_table_size e tmp_table_size forem iguais,
aumente ambos para um valor maior.
Para mais informações sobre como aumentar o valor de tmp_table_size, consulte
tmp_table_size.
