elasticdump: Import and export tools for elasticsearch

version: 2.2.0

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

--input

Source location (required)

--input-index

Source index and type

(default: all, example: index/type)

--output

Destination location (required)

--output-index

Destination index and type

(default: all, example: index/type)

--limit

How many objects to move in batch per operation

limit is approximate for file streams

(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": {} } }'))

--sourceOnly

Output only the json contained within the document _source

Normal: {"_index":"","_type":"","_id":"", "_source":{SOURCE}}

sourceOnly: {SOURCE}

(default: false)

--all

Load/store documents from ALL indexes

(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] )

--timeout

Integer containing the number of milliseconds to wait for

a request to respond before aborting the request. Passed

directly to the request library. Mostly used when you don't

care too much if you lose some data when importing

but rather have speed.

--offset

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,

similar 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

--toLog

When using a custom outputTransport, should log lines

be appended to the output stream?

(default: true, except for `$`)
