Jaeger Persistent Storage with Elasticsearch, Cassandra and Kafka

Running systems in production involve requirements for high availability, resilience and recovery from failure. When running cloud-native applications this becomes even more critical, as the base assumption in such environments is that compute nodes will suffer outages, Kubernetes nodes will go down and microservices instances are likely to fail, yet the service is expected to remain up and running.

What is NoSQL and How is it Utilized?

NoSQL databases use a variety of data models for accessing and managing data. These types of databases are optimized specifically for applications that require large data volume, low latency, and flexible data models, which are achieved by relaxing some of the data consistency restrictions of other databases.

How To Start with Apache Spark and Apache Cassandra

Apache Cassandra is a specific database that scales linearly. This has its price: specific table modelling, configurable consistency and limited analytics. Apple performs millions of operations per second on over 160,000 Cassandra instances while collecting over 100 PBs of data. You can bypass these limited analytics with the Apache Spark and the DataStax connector, and that’s what the story is about.
