------------------------------
Summary: Sqoop2: Avoid massive in-memory copy of schema column
Key: SQOOP-1976
URL: https://issues.apache.org/jira/browse/SQOOP-1976
Project: Sqoop
Issue Type: Improvement
Reporter: Qian Xu
Assignee: Qian Xu
SQOOP-1836 introduced a new method {{getColumnsArray}}. As the class {{Schema}}
is used very often, the idea is to provide a constant (better) lookup time for
particular column. But I think the implementation will create array from a list
for every call, it will be slower than accessing {{getColumnsList}}. SQOOP-1969
has already changed the columns from {{LinkedList}} to {{ArrayList}}, there is
not necessary to have a {{getColumnsArray}} anymore.
