Tags

- Made changes and tested with Grafana 4.4.3 (alerting not supported yet)
- Updated provided dashboards

- Build modified to *not* build collectd modules by default, use the `collectd` maven profile at build time

FEATURES

    Added a Timely client library that contains Java code for interacting with the Timely API. Not all operations are finished.
    Added an analytics module for writing Apache Flink jobs
    Exposed Subscription Scanner configuration settings in the Timely configuration

PERFORMANCE

    AgeOff performance is greatly improved with a new iterator
    Added netty-transport-native-epoll as an optional runtime dependency

NOTES

    Timely has not been tested with Grafana 4.x
    The aggregation function (not the downsample aggregration function) in Grafana did not work prior to this release, it now works.

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.
