=head1 NAME

Paws::RDS::DownloadDBLogFilePortion - Arguments for method DownloadDBLogFilePortion on L<Paws::RDS>

=head1 DESCRIPTION

This class represents the parameters used for calling the method DownloadDBLogFilePortion on the
L<Amazon Relational Database Service|Paws::RDS> service. Use the attributes of this class
as arguments to method DownloadDBLogFilePortion.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to DownloadDBLogFilePortion.

=head1 SYNOPSIS

    my $rds = Paws->service('RDS');
# To list information about DB log files
# This example lists information for the specified log file for the specified DB
# instance.
    my $DownloadDBLogFilePortionDetails = $rds->DownloadDBLogFilePortion(
      'DBInstanceIdentifier' => 'mymysqlinstance',
      'LogFileName'          => 'mysqlUpgrade'
    );


Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object.
For the AWS API documentation, see L<https://docs.aws.amazon.com/goto/WebAPI/rds/DownloadDBLogFilePortion>

=head1 ATTRIBUTES


=head2 B<REQUIRED> DBInstanceIdentifier => Str

The customer-assigned name of the DB instance that contains the log
files you want to list.

Constraints:

=over

=item *

Must match the identifier of an existing DBInstance.

=back


=head2 B<REQUIRED> LogFileName => Str

The name of the log file to be downloaded.


=head2 Marker => Str

The pagination token provided in the previous request or "0". If the
Marker parameter is specified the response includes only records beyond
the marker until the end of the file or up to NumberOfLines.


=head2 NumberOfLines => Int

The number of lines to download. If the number of lines specified
results in a file over 1 MB in size, the file is truncated at 1 MB in
size.

If the NumberOfLines parameter is specified, then the block of lines
returned can be from the beginning or the end of the log file,
depending on the value of the Marker parameter.

=over

=item *

If neither Marker or NumberOfLines are specified, the entire log file
is returned up to a maximum of 10000 lines, starting with the most
recent log entries first.

=item *

If NumberOfLines is specified and Marker isn't specified, then the most
recent lines from the end of the log file are returned.

=item *

If Marker is specified as "0", then the specified number of lines from
the beginning of the log file are returned.

=item *

You can download the log file in blocks of lines by specifying the size
of the block using the NumberOfLines parameter, and by specifying a
value of "0" for the Marker parameter in your first request. Include
the Marker value returned in the response as the Marker value for the
next request, continuing until the AdditionalDataPending response
element returns false.
