> Support getColumnSize method for Schema class
> ---------------------------------------------
>
> Key: SQOOP-1969
> URL: https://issues.apache.org/jira/browse/SQOOP-1969
> Project: Sqoop
> Issue Type: Improvement
> Components: connectors/generic
> Affects Versions: 2.0.0
> Reporter: Jerry Chen
> Assignee: Qian Xu
>
> Currently, Schema class don't have getColumnSize method. There are a lot of
> places in Matcher implementations getMatchingData calling
> getColumnsArray().length to purely get the column size. While getColumnsArray
> a method not efficient as it looks like:
> {quote}
> public Column[] getColumnsArray()
> return columns.toArray(new Column[columns.size()]);
> {quote}
> It is suggested to add getColumnSize method in schema and the caller can use
> this method to return the column length.
> This problem gets serious because getMatchingData is called repeatedly with
> each record in Mapper.
