Summary: [C++][Dataset] Concurrency race in Projector::Project Key: ARROW-7390 URL: https://issues.apache.org/jira/browse/ARROW-7390 Project: Apache Arrow Issue Type: Bug Reporter: Francois Saint-Jacques When a DataFragment is invoked by 2 scan tasks of the same DataFragment, there's a race to invoke SetInputSchema. Note that ResizeMissingColumns also suffers from this race. The ideal goal is to make Project a const method. -- This message was sent by Atlassian Jira (v8.3.4#803005)
