elasticsearch - 如何使用 'best_compression' elasticsearch 数据进行压缩

Question

如何使用“best_compression”选项压缩所有 elasticsearch 数据(现有数据和新数据)？

我知道从 5.00 版本开始，我不能在 elasticsearch.yml 文件中放入“index.codec: best_compression”。我已经阅读了日志，它表明它已被删除，我应该使用

curl -XPUT 'http://localhost:9200/_all/_settings?preserve_existing=true' -d '{"index.codec" : "best_compression"}'

但是在使用时出现以下错误:

{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Can't update non dynamic settings [[index.codec]] for open indices [[logstash-dns-2018.07.30/xHq6UfgsSD2M1dBZhV3cOg], [logstash-2018.07.27/7U7uUsEORFqXtJtrk4KvDw], [logstash-dns-2018.07.27/Xbx15QXOQ5KJAK7iop_54Q], [logstash-http-2018.07.27/q0Rs65a3TjW4NJfcljUHEw], [logstash-flow-2018.07.30/0Erbh2TcRgmFJLMLr8Ka8w], [logstash-2018.07.30/boOd8BdrQV2QoziKaZ_2lw], [logstash-alert-2018.07.27/o5yqwdNqR5yAcbJ-HCNVHw], [logstash-alert-2018.07.30/pp6ZWKLISECVzUiCDDeydQ], [logstash-tls-2018.07.30/rZi6KfC7RtqOVjUt7CCqDQ], [logstash-ssh-2018.07.27/wKi-p6slSqO0-vbwRqS1ZA], [.kibana/XaFQRcEXTW6jLUCmBijzKQ], [logstash-tls-2018.07.27/hbiXYCzjRumh3ND6up9vNw], [logstash-flow-2018.07.27/XfspJr1TS4y6MnCgAmRq1g], [logstash-fileinfo-2018.07.27/9VWyBHsqRmO4QsnN-gdt_w], [logstash-http-2018.07.30/U9JO9Cp-QQO7gvRNoHt7FQ], [logstash-fileinfo-2018.07.30/nlwHeDOsQ3ii8CLxcgE3Ag]]"}],"type":"illegal_argument_exception","reason":"Can't update non dynamic settings [[index.codec]] for open indices [[logstash-dns-2018.07.30/xHq6UfgsSD2M1dBZhV3cOg], [logstash-2018.07.27/7U7uUsEORFqXtJtrk4KvDw], [logstash-dns-2018.07.27/Xbx15QXOQ5KJAK7iop_54Q], [logstash-http-2018.07.27/q0Rs65a3TjW4NJfcljUHEw], [logstash-flow-2018.07.30/0Erbh2TcRgmFJLMLr8Ka8w], [logstash-2018.07.30/boOd8BdrQV2QoziKaZ_2lw], [logstash-alert-2018.07.27/o5yqwdNqR5yAcbJ-HCNVHw], [logstash-alert-2018.07.30/pp6ZWKLISECVzUiCDDeydQ], [logstash-tls-2018.07.30/rZi6KfC7RtqOVjUt7CCqDQ], [logstash-ssh-2018.07.27/wKi-p6slSqO0-vbwRqS1ZA], [.kibana/XaFQRcEXTW6jLUCmBijzKQ], [logstash-tls-2018.07.27/hbiXYCzjRumh3ND6up9vNw], [logstash-flow-2018.07.27/XfspJr1TS4y6MnCgAmRq1g], [logstash-fileinfo-2018.07.27/9VWyBHsqRmO4QsnN-gdt_w], [logstash-http-2018.07.30/U9JO9Cp-QQO7gvRNoHt7FQ], [logstash-fileinfo-2018.07.30/nlwHeDOsQ3ii8CLxcgE3Ag]]"},"status":400}

解决了:

关闭所有索引:

http://localhost:9200/_all/_close '

将 best_compression 应用于所有

curl -XPUT ' http://localhost:9200/_all/_settings ' -d '{"index.codec": "best_compression"}'

打开所有索引:

curl -XPOST ' http://localhost:9200/_all/_open '
