[jira] [Created] (ARROW-5983) [C++] Provide bulk method on TypedBufferBuilder for appending a bitmap

Wes McKinney created ARROW-5983:
-----------------------------------

             Summary: [C++] Provide bulk method on TypedBufferBuilder<bool> for appending a bitmap
                 Key: ARROW-5983
                 URL: https://issues.apache.org/jira/browse/ARROW-5983
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wes McKinney


We have {{TypedBufferBuilder<bool>::UnsafeAppend}} for an array of bytes (where non-zero becomes 1), but it would be useful to have also {{UnsafeAppendBits}} so that bitmaps coming from {{arrow::Array}} can also be appended
