Right, I'm not sure the slowdown on an in-memory buffer is too significant (cc @pitrou for opinions too), though it seems we should find some way for the cache to avoid madvise/WillNeed in this case (since it's purely wasted work right?) But it seems reading all columns would be a common operation and it would be nice to avoid the slowdown there. -- This is an automated message from the Apache Git Service.
