En este capítulo trataremos:
Cómo MongoDB garantiza la durabilidad a nivel de los miembros del conjunto de réplicas mediante el registro en diario
Cómo MongoDB garantiza la durabilidad a nivel de clúster utilizando la preocupación por la escritura
Cómo configurar tu aplicación y tu clúster MongoDB para que te proporcionen el nivel de durabilidad que necesitas
Cómo MongoDB garantiza la durabilidad a nivel de clúster utilizando la preocupación por la lectura
