Boaz Leskes created LUCENE-5145:
-----------------------------------
Summary: Added AppendingPackedLongBuffer & extended
AbstractAppendingLongBuffer family (customizable compression ratio + bulk
retrieval)
Key: LUCENE-5145
URL: https://issues.apache.org/jira/browse/LUCENE-5145
Project: Lucene - Core
Issue Type: Improvement
Reporter: Boaz Leskes
Made acceptableOverheadRatio configurable
Added bulk get to AbstractAppendingLongBuffer classes, for faster retrieval.
Introduced a new variant, AppendingPackedLongBuffer which solely relies on
PackedInts as a back-end. This new class is useful where people have
non-negative numbers with a fairly uniform distribution over a fixed (limited)
range. Ex. facets ordinals.
To distinguish it from AppendingPackedLongBuffer, delta based
AppendingLongBuffer was renamed to AppendingDeltaPackedLongBuffer
Fixed an Issue with NullReader where it didn't respect it's valueCount in bulk
gets.
