----------------------------------
Summary: [C++] Reintroduce DictionaryBuilder
Key: ARROW-1882
URL: https://issues.apache.org/jira/browse/ARROW-1882
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Uwe L. Korn
Priority: Critical
Fix For: 0.8.0
We need the {{DictionaryBuilder}} to incrementally build Arrow Arrays of
{{DictionaryType}}. The kernels only support en-bloc conversions of Arrays
which yields a higher memory usage.
