0.0.3 Release

FEATURES

• Configuration file format changed to YAML due to use of Spring Configuration and Spring Boot
• Removed Double Lexicoder in Accumulo Value, requires removal of old data
• Added support for put operations in binary form using Google FlatBuffers
• Updated docker image
• Ageoff (in days) for individual metrics now possible, default value supported. Ageoff iterators are removed and re-applied during startup.
• Timely works with Accumulo 1.7 and 1.8
• Added support for PUT in text and binary form over UDP

PERFORMANCE

• Modified code to use one ageoff iterator instead of a stack of them
• Removed interpolation code and code that handles counters in a special manner. This should be done in the client.
• Moved rate calculation to the tablet server by using an iterator that groups time series together and then applies a filter

NOTES

1. This list of jars that are needed on the tablet server has increased and now includes:
   • commons-lang3
   • commons-collections4
   • guava
   • timely-client
   • timely-server

Additionally, the Accumulo classloader has to be configured for post-delegation given that the version of Guava that we depend on is
newer than what Accumulo and Hadoop uses.

1. The counter checkbox in the Grafana U/I does nothing. We are looking to fix this up in the next release.
