To add > full support, we need an interface that supports either single batches or > hyper batches. Accessing vectors in hyper batches differs depending on > whether the vector is at the top level or is nested. SeeĀ [this > post|https://github.com/paul-rogers/drill/wiki/BH-Column-Readers] for > details. Also includes a simpler reader template: replaces the original three > classes with one, in parallel with the writers. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
