SYNOPSIS
               use Data::Stream::Bulk::DBI;

               my $sth = $dbh->prepare("SELECT hate FROM sql"); # very big resultset

               return Data::Stream::Bulk::DBI->new(
                       sth => $sth,
                       max_rows => $n, # how many at a time
                       slice => [ ... ], # if you want to pass the first param to fetchall_arrayref
               );

DESCRIPTION
       This implementation of Data::Stream::Bulk api works with DBI statement handles, using
       "fetchall_arrayref" in DBI.

       It fetches "max_rows" at a time (defaults to 500).

ATTRIBUTES
       sth The statement handle to call "fetchall_arrayref" on.

       slice
           Passed verbatim as the first param to "fetchall_arrayref". Should usually be "undef",
           provided for completetness.

       max_rows
           The second param to "fetchall_arrayref". Controls the size of each buffer.

           Defaults to 500.

METHODS
       get_more
           See Data::Stream::Bulk::DoneFlag.

           Calls "fetchall_arrayref" to get the next chunk of rows.

       all Calls "fetchall_arrayref" to get the raminder of the data (without specifying
           "max_rows").
