=head1 NAME
Data::Stream::Bulk::Chunked - combine streams into larger chunks
=head1 VERSION
version 0.11
=head1 SYNOPSIS
use Data::Stream::Bulk::Chunked;
Data::Stream::Bulk::Chunked->new(
stream => $s,
chunk_size => 10000,
);
=head1 DESCRIPTION
This is a stream which wraps an existing stream to give more items in a single
block. This can simplify application code which does its own processing one
block at a time, and where processing larger blocks is more efficient.
=head1 ATTRIBUTES
=over 4
=item stream
The stream to chunk. Required.
=item chunk_size
The minimum number of items to return in a block. Defaults to 1 (which does
nothing).
=back
=head1 METHODS
=over 4
=item get_more
See L<Data::Stream::Bulk::DoneFlag>.
Returns at least C<chunk_size> items. Note that this isn't guaranteed to return
exactly C<chunk_size> items - it just returns multiple full blocks from the
backend. Also, the final block returned may have less than C<chunk_size> items.
