=head1 NAME

Bio::EnsEMBL::Compara::RunnableDB::CopyDataWithJoin

=head1 DESCRIPTION

Simple wrapper around Utils::CopyData::copy_data that can copy large
chunks of data much faster than eHive's dataflow-into-a-table mechanism.

=over

=item inputquery

A SQL query to feed the transfer. It is executed in eHive's "data" source,
which is set by the parameter "db_conn", and otherwise defaults to the
current database.

=item table

The name of the table to store the data in. The Runnable assumes that the
input query fills all the columns.
