## NAME
    [Data::Stream::Bulk::Chunked](https://www.chedong.com/phpMan.php/perldoc/Data%3A%3AStream%3A%3ABulk%3A%3AChunked/markdown) - combine streams into larger chunks

## VERSION
    version 0.11

## SYNOPSIS
      use [Data::Stream::Bulk::Chunked](https://www.chedong.com/phpMan.php/perldoc/Data%3A%3AStream%3A%3ABulk%3A%3AChunked/markdown);

      [Data::Stream::Bulk::Chunked](https://www.chedong.com/phpMan.php/perldoc/Data%3A%3AStream%3A%3ABulk%3A%3AChunked/markdown)->new(
          stream     => $s,
          chunk_size => 10000,
      );

## 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.

## ATTRIBUTES
    stream
        The stream to chunk. Required.

    chunk_size
        The minimum number of items to return in a block. Defaults to 1 (which does nothing).

## METHODS
    get_more
        See [Data::Stream::Bulk::DoneFlag](https://www.chedong.com/phpMan.php/perldoc/Data%3A%3AStream%3A%3ABulk%3A%3ADoneFlag/markdown).

        Returns at least "chunk_size" items. Note that this isn't guaranteed to return exactly
        "chunk_size" items - it just returns multiple full blocks from the backend. Also, the final
        block returned may have less than "chunk_size" items.
