Adrien Grand updated LUCENE-7521:
---------------------------------
Attachment: LUCENE-7521.patch
Here is a patch. It removes the Direct* and Packed*ThreeBlocks impls which were
just specializations of Packed64 for given numbers of bits per value. It also
makes sure that PackedInts.fastestFormatAndBits doesn't use the
PACKED_SINGLE_BLOCK format anymore so that we can remove it in Lucene 8.

> We have a lot of specialization in PackedInts about how to keep packed arrays
> of longs in memory. However, most use-cases have slowly moved to DirectWriter
> and DirectMonotonicWriter and most specializations we have are barely used
> for performance-sensitive operations, so I'd like to clean this up a bit.
