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