anchor.diff:  === Block size
   
   The compressed blocks are created with a 27 bit header (unlike in the original paper, which uses a 14 bit delta header). This allows to
  -use up to one day block using millisecond precision. However, as noted in the paper, the compression ratio does not usually improve with blocks larger than 2 hours.
  +use up to one day block size using millisecond precision.

positive.code: == Introduction
  
  This is Java based implementation of the compression methods described in the paper link:http://www.vldb.org/pvldb/vol8/p1816-teller.pdf["Gorilla: A Fast, Scalable, In-Memory Time Series Database"]. For explanation on how the compression methods work, read the excellent paper.
