> In LOLoad.getProjectionMap(), the private method determineSchema() is called
> which inturn calls LoadMetadata.getSchema() - the latter call could
> potentially be expensive if the input file is read to determine the schema or
> a metadata system is contacted to get the schema - determineSchema() can
> cache the schema it gets so that subsequent calls use the cached version.
