Questions tagged [fiware-cygnus]

fiware-cygnus tag refers to the Cygnus connector implementation (FIWARE platform), allowing for Orion context data persistence in an historical way in several different storages such as HDFS, MySQL or CKAN

Cygnus is a data connector within FIWARE platform allowing for Orion context data persistence in an historical way in several different storages such as HDFS, MySQL or CKAN. Cygnus characteristics are:

  • It is based in Apache Flume, expanding the core elements with custom sinks, http handlers, channel selectors and interceptors among others.
  • Smart destination (HDFS file, MySQL table or CKAN resource) extraction based on data properties.
  • Automatic Hive tables creation when using HDFS sinks.
  • Support for multiple persistence models (json-row, json-column, ...)
