-----------------------------------
Summary: [C#] Array builders to use bit-packed buffer builder
rather than boolean array builder for validity map
Key: ARROW-8788
URL: https://issues.apache.org/jira/browse/ARROW-8788
Project: Apache Arrow
Issue Type: Improvement
Components: C#
Affects Versions: 0.17.0
Reporter: Adam Szmigin
The C# array builders were recently enhanced to have support for adding
nullable values easily, under [PR
#7032|https://github.com/apache/arrow/pull/7032].
However, the builders internally referenced {{BooleanArray.Builder}}, which
itself then had logic "baked-in" for efficient bit-packing of boolean values
into a byte buffer.
It would be cleaner for there to be a general-purpose bit-packed buffer
builder, and for all array builders to use that for their validity map. The
boolean array builder would use it twice: once for values, once for validity.
