Information

• Uses Cassandra
• Does not support TAGs (source)
• Does not support SUM (source)
  • Using MIN instead of SUM in YCSB-TS
• Elastic Search (ES) is optional for searching metrics (not needed for YCSB-TS, only using one known metric)
• Unclear how to combine multiple instances of blueflood
  • Zookeeper can be used to coordinate Rollups and shard locking (Source1, Source2)
  • Unclear if and how load can be distributed
  • Multiple cassandra nodes can be used for one shard. If one node fails, a non-failing one takes over.
• Only support for the following granularities: 5, 60, 240, 1440
• Due to the size of the .jar file (72 MB) and a long buildprocess, the jar file is downloaded in TSDBBench instead of built everytime

How to install/build:

• sudo apt-get install maven openjdk-7-jdk
• git clone https://github.com/rackerlabs/blueflood.git
• cd blueflood
• mvn test integration-test
• mvn package -P all-modules
• The result (if the build process was successful) is in blueflood-all/target/blueflood-all-2.0.0-SNAPSHOT-jar-with-dependencies.jar
