Latest commit af93a8d Jan 19, 2017 @leventov leventov committed with fjy Sequences refactorings and removed unused code (part of #3798) (#3693)
* Removing unused code from io.druid.java.util.common.guava package; fix #3563 (more consistent and paranoiac resource handing in Sequences subsystem); Add Sequences.wrap() for DRY in MetricsEmittingQueryRunner, CPUTimeMetricQueryRunner and SpecificSegmentQueryRunner; Catch MissingSegmentsException in SpecificSegmentQueryRunner's yielder.next() method (follow up on #3617)

* Make Sequences.withEffect() execute the effect if the wrapped sequence throws exception from close()

* Fix strange code in MetricsEmittingQueryRunner

* Add comment on why YieldingSequenceBase is used in Sequences.withEffect()

* Use Closer in OrderedMergeSequence and MergeSequence to close multiple yielders

Druid

Druid is a distributed, column-oriented, real-time analytics data store that is commonly used to power exploratory dashboards in multi-tenant environments.

Druid excels as a data warehousing solution for fast aggregate queries on petabyte sized data sets. Druid supports a variety of flexible filters, exact calculations, approximate algorithms, and other useful calculations.

Druid can load both streaming and batch data and integrates with Samza, Kafka, Storm, Spark, and Hadoop.
