在ElasticSearch中重新索引索引以更改碎片数 [英] Re-indexing an index in ElasticSearch to change the number of shards

问题描述

我需要更改索引中的碎片数。该索引相当大，我可能必须在配置10-15次之前进行测试，以便我对结果感到满意。有没有一个工具提供开箱即用的这种功能？或者是最简单的方式来实现这一点？

I need to change the number of shards in my index. The index is quite big and i may have to change the configuration 10-15 times for testing purposes before i'm satisfied with the result. is there a tool offering out of the box this kind of functionality? or what's the easiest way of accomplishing this?

推荐答案

Perl 和 Ruby 客户端直接支持重新索引。

Both the Perl and Ruby clients directly support reindexing.

在Perl中，您可以：

In Perl, you'd do:

my $source = $es->scrolled_search(
    index       => 'old_index',
    search_type => 'scan',
    scroll      => '5m',
    version     => 1
);

$es->reindex(
    source      => $source,
    dest_index  => 'new_index'
);

在Ruby中，你'd do：

In Ruby, you'd do:

Tire.index('old').reindex 'new', settings: { number_of_shards: 3 }
