Many companies use both elasticsearch and cassandra, typically in the form of logs or time series, but managing many softwares at a large scale can be quite challenging. Elassandra tightly integrates elasticsearch within cassandra as a secondary index, allowing near-realtime search with all existing elasticsearch APIs, plugins and tools like Kibana. We will present the core concepts of elassandra and explain how it draws benefit from internal cassandra features to make elasticsearch masterless, scalable with automatic resharding, more reliable and more efficient than deploying both softwares. We will also explore the bidirectional mapping : the way elasticsearch automatically creates the corresponding cassandra schema and the way elasticsearch indexes an existing cassandra table. Furthermore, we will share some use cases and benchmark results demonstrating practical use of elassandra to scale-out, re-index with zero-downtime, search and visualize data with various tools.
