支持多个版本间的数据迁移,使用scroll+bulk
1.版本支持1.x,2.x.5.0 (0.x未测试)
2.支持http basic auth 认证的es集群
3.支持导入覆盖索引名称(目前只支持单个索引导入的情况下可指定)
4.支持index setting和mapping的同步(相关es大版本,2.x和5.0之间不支持)
5.支持dump到本地文件
6.支持从dump文件加载导入到指定索引
欢迎测试!

执行命令如下:
./esm -sxxl:9200 -d xx:9200 -x bai -y bai -w=10 -b=10 -c 10000

一直卡在这个界面,目标集群也没有建立索引和同步数据!?请问这个是什么原因,
版本是2.3->2.3

你好,我的elasticsearch版本是6.1.4,数据使用了join类型,使用楼主工具迁移数据出现一个问题。总共有6条数据,日志显示6条都成功,但是es中只查到3条。(我的数据总共三层,如a<---b<---c),最终es只有最上层a的数据,请问工具对join的支持情况?
只能一个一个索引进行迁移嘛? 可以把所有的索引一次性全部迁移过来的嘛?

一次索引太多会造成 HTTP请求太长了 ,修改 es 的参数可以调整:
http.max_initial_line_length: "8k"
http.max_header_size: "16k"
http.max_initial_line_length: "8k"
http.max_header_size: "16k"
作者你好,请问一下migration能在采集器正常采集的情况下进行数据迁移么,会丢数据么
您好,medcl大神,打扰您,像您请请教个问题。昨天我使用您的esm v0.4.3版本,进行es数据复制。使用过程中,命令执行的服务器会突然卡死,无法连接,console也无法连接,监控数据不再更新,在能看到的最后监控也没有太多异常,会有cpu使正常占用和上下文切换较高,然后就突然夯住了。命令是 esm -s http://aaa -d http://bbb -x ccc -y bbb -w 5 --sluced_scroll_size=5 。我们有6个集群,基本容量一样,昨天执行备份多个索引,出现2个服务器hangs情况,不敢再执行了,请问您能指点一下可能的原因吗?

copy_mapping后面有s,你可以去掉这个参数,另外相同版本才建议直接copy mapping

请问如何后台运行,并能在后台日志中看到进度条呢
两种方法,第一种可以使用 screen 命令来切后台,第二种是使用 nohup 和&切换到后台,不过这种方法就不能显示进度条了。
支持aliases 导出吗?
但我使用v0.5.0版本的esm命令,执行esm -s elastic:changeme@xxx:9200 -d elastic:changeme@xxx:9200 -x other_v1 -w=5 -b=10 -c 10000 -a --all --copy_settings --copy_mappings --force --refresh ,
导入后查看GET _other_v1/_alias是少别名的,是使用的参数不对吗

参考 GitHub 里面的 readme,copy-mapping 不建议用了,建议手动提取创建好索引,确认没问题之后再使用 esm 导数据,主要是各种版本之间不兼容,比较难处理,如果等到倒完数据再检查 mapping 就比较麻烦,要重新倒。
如何自己编译安装新版的迁移工具,例如v0.6.0或v0.6.1
目前可以支持多个索引dump到本地,然后再导入集群吗?
