Rhombus

• https://github.com/Pardot/Rhombus

Information

• Rhombus is a library that uses Cassandra, no seperate running daemon
• Creates a Cassandra Keyspace at init()
• The cassandra layout must be given in a json file
  • Amount of TAGs is not dynamic!
• No AVG() or SUM() and therefore no granularity choosable

Implementation Notes

• 3 TAGs are supported by default (same as SQL)
• “ShardingStrategyNone” is used as strategy since it is not expected that tag wide rows overflow
• Nothing must be installed on the server besides Cassandra
• COUNT() instead of AVG()/SUM()
