[ANNOUNCE] Apache Lens 2.7.1 released

[Raju Bairishetti]

Hi All,

The Apache Lens team is proud to announce the release of Apache Lens
2.7.1.

This release includes features like cube segmentation, unioning data across
facts, retry on transient errors, support for source data completion
checking and many more bug fixes and improvements.

Apache Lens provides a Unified Analytics interface. Lens aims to cut the
Data Analytics silos by providing a single view of data across multiple
tiered data stores and optimal execution environment for the analytical
query. It seamlessly integrates Hadoop with traditional data warehouses to
appear like one.


More details on Apache Lens can be found at
http://lens.apache.org/

Getting started available at
http://lens.apache.org/lenshome/quick-start.html

For quick ramp-up, you can watch a video at
http://cwiki.apache.org/confluence/display/LENS/2015/07/13/20+Minute+video+demo+of+Apache+Lens+through+examples

How to for Contributors available at
http://lens.apache.org/developer/contribute.html

The release artifacts are downloadable from
http://lens.apache.org/releases/download.html

Maven jar artifacts have also been made available on
https://repository.apache.org/content/repositories/releases/org/apache/lens

Release notes available at
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315923=12336851

We would like to thank all the contributors who made this release possible.


Thanks,

> Current algorithm: 
> * Create bitmap (equivalent to powerset)
> * from the powerset, add sets which can complete all time ranges as candidates
> * Prune sets which are contained in other sets
> Proposed change:
> The following recursion implemented iteratively: 
> {code}
> (ignoring cubeql for clarity)
> getCombinations(candidates) = getCombinationsRecursive(emptyList(), 
> candidates)
> getCombinationsRecursive(incompleteCombinations: List, 
> candidates: List) =
> head, tail = head and tail of linked List candidates
> add head to all elements of incompleteCombinations.
> add {{ [head] }} as one incompleteCombination.
> complete = remove now complete combinations from incompleteCombinations
> return {{complete ++ 
> getCombinationsTailRecursive(incompleteCombinations+[head], tail)}}
> {code}
> The improvement is, that redundant union candidates like {a,b,c} won't be 
> generated if {a,b} is already covering time ranges. This will only generate 
> minimal sets that cover time ranges. So the memory footprint isn't O( 2^n ) 
> anymore.
