导出es数据方法例子:

# elasticdump --input=http://192.168.0.1:9200/test --output=/data/elas_backup/test.json --type=data

Tue, 28 Aug 2018 09:15:54 GMT | starting dump

Tue, 28 Aug 2018 09:15:55 GMT | got 100 objects from source elasticsearch (offset: 0)

Tue, 28 Aug 2018 09:15:55 GMT | sent 100 objects to destination file, wrote 100

Tue, 28 Aug 2018 09:15:55 GMT | got 100 objects from source elasticsearch (offset: 100)

Tue, 28 Aug 2018 09:15:55 GMT | sent 100 objects to destination file, wrote 100

Tue, 28 Aug 2018 09:15:55 GMT | got 100 objects from source elasticsearch (offset: 200)

导入es数据方法例子:

# elasticdump --input=/data/elas_backup/test.json --output=http://192.168.0.1:9200 --type=data

Tue, 28 Aug 2018 09:15:54 GMT | starting dump

Tue, 28 Aug 2018 09:15:55 GMT | got 100 objects from source elasticsearch (offset: 0)

Tue, 28 Aug 2018 09:15:55 GMT | sent 100 objects to destination file, wrote 100

从一个索引的数据迁移到另外一个索引的数据:

# elasticdump --ignore-errors=true --scrollTime=120m --bulk=true --input=http://192.168.0.1:9200/test --output=http://192.168.0.1:9200/chenfeng --type=data

备注:

--ignore-errors=true --scrollTime=120m --bulk=true 是批量导入参数

导出表结构mapping:

# elasticdump --input=http://192.168.0.1:9200/test --output=test-mapping.json --type=mapping

Wed, 29 Aug 2018 09:01:41 GMT | starting dump

Wed, 29 Aug 2018 09:01:42 GMT | got 1 objects from source elasticsearch (offset: 0)

Wed, 29 Aug 2018 09:01:42 GMT | sent 1 objects to destination file, wrote 1

Wed, 29 Aug 2018 09:01:42 GMT | got 0 objects from source elasticsearch (offset: 1)

Wed, 29 Aug 2018 09:01:42 GMT | Total Writes: 1
