=head1 NAME

Search::Elasticsearch::Client::8_0::Direct::Cat - A client for running cat debugging requests

=head1 VERSION

version 8.12

=head1 DESCRIPTION

The C<cat> API in Elasticsearch provides information about your
cluster and indices in a simple, easy to read text format, intended
for human consumption.

These APIs have a number of parameters in common:

=over

=item * C<help>

Returns help about the API, eg:

    say $e->cat->allocation(help => 1);

=item * C<v>

Includes the column headers in the output:

    say $e->cat->allocation(v => 1);

=item * C<h>

Accepts a list of column names to be output, eg:

    say $e->cat->indices(h => ['health','index']);

=item * C<bytes>

Formats byte-based values as bytes (C<b>), kilobytes (C<k>), megabytes
(C<m>) or gigabytes (C<g>)

=back

It does L<Search::Elasticsearch::Role::Client::Direct>.
