13 The "cat" API in Elasticsearch provides information about your cluster
14 and indices in a simple, easy to read text format, intended for human
15 consumption.
16 These APIs have a number of parameters in common:
18 • "help"
20 Returns help about the API, eg:
22 say $e->cat->allocation(help => 1);
24 • "v"
26 Includes the column headers in the output:
28 say $e->cat->allocation(v => 1);
30 • "h"
32 Accepts a list of column names to be output, eg:
34 say $e->cat->indices(h => ['health','index']);
36 • "bytes"
38 Formats byte-based values as bytes ("b"), kilobytes ("k"),
40 megabytes ("m") or gigabytes ("g")
41 It does Search::Elasticsearch::Role::Client::Direct.
