KairosDB
KairosDB is a fast time-series database on top of Apache Cassandra. In the previous chapter, we learned about OpenTSDB, which is based on HBase and has recently introduced support for Apache Cassandra. KairosDB, similarly, has a very active and smart community and a very flexible API to build plugins. The APIs of KairosDB are very similar to OpenTSDB, so we can replace this implementation with OpenTSDB with minimum effort.
To make KairosDB ready to ingest data from Apache Kafka, we need to perform the following steps:
- Install Apache Cassandra (one node is enough for our exercise)
- Install KairosDB
- Develop and deploy the KairosDB plugin to consume data from Apache Kafka
