Description

HBase 1.3.1 with head of Phoenix 4.x with/without PHOENIX-3827 v2 patch applied. This is with immutable non-covered local/global index on a single column with varying batch size when writing data to base table plus index.

Batch Size	Local Index with PHOENIX-3827_v2 patch (sec)	Local Index without PHOENIX-3827_v2.patch (sec)	Global (sec)
100	0.02	0.03	0.013
1000	0.3	0.3	0.13
10000	4.3	2.6	1.3
12500	8.1	3	1.6
15000	13.3	3.1	1.9
