elasticdump: Import and export tools for elasticsearch

Usage: elasticdump --input SOURCE --output DESTINATION [OPTIONS]

--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.

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"}}}'
