Beneficios¶

Descentralizado - Todos los nodos del clúster tiene el mismo papel. No hay ningún punto único de fallo. Los datos se distribuyen a través del clúster (de modo que cada nodo contiene datos diferentes), pero no hay maestro como cada nodo puede dar servicio a cualquier petición.
Compatible con la replicación y la replicación de datos multi centro - estrategias de replicación son configurables. Cassandra está diseñado como una distribuida sistema, para el despliegue de un gran número de nodos a través de múltiples centros de datos. Las principales características de la arquitectura distribuida de Cassandra son adaptada específicamente para el despliegue de centroizquierda de datos múltiples, para la redundancia, la conmutación por error y recuperación de desastres.
Escalabilidad - Leer y escribir el rendimiento tanto de aumento lineal a medida que se añaden nuevas máquinas, sin tiempo de inactividad o interrupción de las aplicaciones.
Tolerante a errores - Los datos se replican automáticamente a múltiples nodos para la tolerancia a fallos. La replicación a través de múltiples centros de datos es apoyado. Nodos fallidos pueden ser reemplazados sin tiempo de inactividad.
Consistencia Tunable - Escribe y lee ofrecer un nivel ajustable de la coherencia, todo el camino de “escribe nunca fallan” a “bloque para todas las réplicas sea legible”, con el nivel de quórum en el medio.
