elasticdump: Import and export tools for elasticsearch

NAME

elasticdump - Import and export tools for elasticsearch

SYNOPSIS

elasticdump ,--input SOURCE --output DESTINATION /[,OPTIONS/]

DESCRIPTION

--input
Source location (required)
--output
Destination location (required)
--limit
How many objects to move in bulk per operation (default: 100)
--debug
Display the elasticsearch commands being used (default: false)
--type
What are we exporting? (default: data, options: [data, mapping])
--delete
Delete documents one-by-one from the input as they are moved. Will not delete the source index
(default: false)
--searchBody
Preform a partial extract based on search results (when ES is the input, default: '{"query": { "match_all": {} } }')
--all
Load/store documents from ALL indexes (default: false)
--bulk
Leverage elasticsearch Bulk API when writing documents (default: false)
--ignore-errors
Will continue the read/write loop on write error (default: false)
--scrollTime
Time the nodes will hold the requested search in order. (default: 10m)
--maxSockets
How many simultaneous HTTP requests can we process make? (default: 5 [node <= v0.10.x] / Infinity [node >= v0.11.x] )
--bulk-use-output-index-name
Force use of destination index name (the actual output URL) as destination while bulk writing to ES. Allows leveraging Bulk API copying data inside the same elasticsearch instance. (default: false)
--timeout
Integer containing the number of milliseconds to wait for a request to respond before aborting the request. Passed directly to the request library. If used in bulk writing, it will result in the entire batch not being written. Mostly used when you don't care too much if you lose some data when importing but rather have speed.
--skip
Integer containing the number of rows you wish to skip ahead from the input transport. When importing a large index, things can go wrong, be it connectivity, crashes, someone forgetting to `screen`, etc. This allows you to start the dump again from the last known line written (as logged by the `offset` in the output). Please be advised that since no sorting is specified when the dump is initially created, there's no real way to guarantee that the skipped rows have already been written/parsed. This is more of an option for when you want to get most data as possible in the index without concern for losing some rows in the process, gsimilar to the `timeout` option.
--inputTransport
Provide a custom js file to us as the input transport
--outputTransport
Provide a custom js file to us as the output transport

EXAMPLES

Copy an index from production to staging with mappings:

elasticdump \ --input=http://production.es.com:9200/my_index \ --output=http://staging.es.com:9200/my_index \ --type=mapping
elasticdump \
--input=http://production.es.com:9200/my_index \ --output=http://staging.es.com:9200/my_index \ --type=data
Backup index data to a file:
elasticdump \
--input=http://production.es.com:9200/my_index \ --output=/data/my_index_mapping.json \ --type=mapping
elasticdump \
--input=http://production.es.com:9200/my_index \ --output=/data/my_index.json \ --type=data
Backup and index to a gzip using stdout:
elasticdump \
--input=http://production.es.com:9200/my_index \ --output=$ \ | gzip > /data/my_index.json.gz
Backup ALL indices, then use Bulk API to populate another ES cluster:
elasticdump \
--all=true \ --input=http://production-a.es.com:9200/ \ --output=/data/production.json
elasticdump \
--bulk=true \ --input=/data/production.json \ --output=http://production-b.es.com:9200/
Backup the results of a query to a file:
elasticdump \
--input=http://production.es.com:9200/my_index \ --output=query.json \ --searchBody '{"query":{"term":{"username": "admin"}}}'
