But, it does so by reusing the > {{MaterializedField}} from the original vector. Though the original authors > of {{MaterializedField}} apparently meant it to be immutable, later changes > for maps and unions ended up changing it to add members. > When cloning a map, we get the original map materialized field, then start > doctoring it up as we add the cloned map members. This screws up the original > map vector's metadata. > The solution is to clone an empty version of the materialized field when > creating a new vector. > But, since much code creates vectors by giving a perfectly valid, unique > materialized field, we want to add a new method for use by the ill-behaved > uses, such as PartitionSender, that ask to create a new vector without > cloning the materialized field. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
