En esta página, se describe cómo administrar la cantidad de tablas temporales. Este recommender se llama Reconfigura los parámetros de la tabla temporal.
Todos los días, este recomendador analiza la cantidad de tablas temporales que se crean en el disco en comparación con la cantidad total de tablas temporales. Si la cantidad de tablas temporales creadas en el disco es superior al 20% de la cantidad total de tablas, este recomendador te recomienda realizar una de las siguientes acciones:
Aumenta el valor de la marca tmp_table_size o la marca max_heap_table_size, o ambas.
Si los valores de max_heap_tmp_table_size y tmp_table_size no son iguales, aumenta el valor más pequeño para que coincida con el valor más grande.
Si los valores de max_heap_tmp_table_size y tmp_table_size son los mismos, aumenta ambos a un valor más alto.
Para obtener más información sobre cómo aumentar el valor de tmp_table_size, consulta tmp_table_size.

Aplica la recomendación
Para implementar esta recomendación, haz una de las siguientes acciones:
Si los valores de las marcas max_heap_tmp_table_size y tmp_table_size no son iguales, aumenta el valor más pequeño para que coincida con el valor más grande.
Si los valores para las marcas max_heap_tmp_table_size y tmp_table_size son los mismos, aumenta ambos a valores más grandes.
