Antoine Pitrou resolved ARROW-5354. ----------------------------------- Resolution: Won't Fix As discussed in the linked PR, this isn't currently desirable. > [C++] allow Array to have null buffers when all elements are null > ----------------------------------------------------------------- > > Key: ARROW-5354 > URL: https://issues.apache.org/jira/browse/ARROW-5354 > Project: Apache Arrow > Issue Type: New Feature > Components: C++ > Reporter: Benjamin Kietzman > Assignee: Benjamin Kietzman > Priority: Minor > Labels: pull-request-available > Time Spent: 1h 40m > Remaining Estimate: 0h > > In the case of all elements of an array being null, no buffers whatsoever > *need* to be allocated (similar to NullArray). This is a more extreme case of > the optimization which allows the null bitmap buffer to be null if all > elements are valid. Currently {{arrow::Array}} requires at least a null > bitmap buffer to be allocated (and all bits set to 0). -- This message was sent by Atlassian Jira (v8.3.4#803005)
