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 Clinton Gormley的帖子。
在Ruby中,你'd do:
In Ruby, you'd do:
Tire.index('old').reindex 'new', settings: { number_of_shards: 3 }在相关轮胎提交。
