Learn how to leverage external persistent volumes to enhance recovery times and achieve high availability for distributed applications on DC/OS. Explore the benefits of using dcos-commons frameworks for Cassandra, Elasticsearch, HDFS, Kafka, and Spark in conjunction with external persistent storage solutions. Discover techniques to reduce data recovery time after node failures, maintain application performance during bootstrapping, and improve overall system resilience. Gain insights into block-level replication, dynamic volume resizing, and the advantages of using Portworx for distributed storage. Watch a demonstration of Portworx deployment and its integration with Cassandra on DC/OS, and understand how to effectively handle node failures and maintain data integrity in distributed environments.
