Tools for moving and saving indices.
- Version
1.0.0of Elasticdump changes the format of the files created by the dump. Files created with version0.x.xof this tool are likely not to work with versions going forward. To learn more about the breaking changes, vist the release notes for version1.0.0. If you recive an "out of memory" error, this is probably or most likely the cause. - Version
2.0.0of Elasticdump removes thebulkoptions. These options were buggy, and differ between versions of Elasticsearch. If you need to export multiple indexes, look for themultielasticdumpsection of the tool. - Version
2.1.0of Elasticdump moves from usingscan/scroll(ES 1.x) to justscan(ES 2.x). This is a backwards-compatible change within Elasticsearch, but performance may suffer on Elasticsearch versions prior to 2.x. - Version
3.0.0of Elasticdump has the default queries updated to only work for ElasticSearch version 5+. The tool may be compatible with earlier versions of Elasticsearch, but our version detection method may not work for all ES cluster topologies - Version
5.0.0of Elasticdump contains a breaking change for the s3 transport. s3Bucket and s3RecordKey params are no longer supported please use s3urls instead - Version
6.1.0and higher of Elasticdump contains a change to the upload/dump process. This change allows for overlapping promise processing. The benefit of which is improved performance due increased parallel processing, but a side-effect exists where-by records (data-set) aren't processed in a sequential order (the ordering is no longer guaranteed) - Version
6.67.0and higher of Elasticdump will quit if the node version does not match the minimum requirement needed (v10.0.0)

npm install elasticdump
./bin/elasticdump(global)
npm install elasticdump -g
elasticdumpElasticdump works by sending an input to an output. Both can be either an elasticsearch URL or a File.
Elasticsearch:
- format:
{protocol}://{host}:{port}/{index} - example:
http://127.0.0.1:9200/my_index
File:
- format:
{FilePath} - example:
/Users/evantahler/Desktop/dump.json
Stdio:
- format: stdin / stdout
- format:
$
You can then do things like:

Elasticsearch:
- format:
{protocol}://{host}:{port}/{sub}/{directory...} - example:
http://127.0.0.1:9200/api/search
# Copy a single index from a elasticsearch:

If you prefer using docker to use elasticdump, you can download this project from docker hub:
docker pull elasticdump/elasticsearch-dumpThen you can use it just by :
- using
docker run --rm -ti elasticdump/elasticsearch-dump - you'll need to mount your file storage dir
-v <your dumps dir>:<your mount point>to your docker container
Example:
# Copy an index from production to staging with mappings:
docker run --rm -ti elasticdump/elasticsearch-dump \
--input=http://production.es.com:9200/my_index \
--output=http://staging.es.com:9200/my_index \
--type=mapping
docker run --rm -ti elasticdump/elasticsearch-dump \
--input=http://production.es.com:9200/my_index \
--output=http://staging.es.com:9200/my_index \
--type=data
# Backup index data to a file:
docker run --rm -ti -v /data:/tmp elasticdump/elasticsearch-dump \
--input=http://production.es.com:9200/my_index \
--output=/tmp/my_index_mapping.json \
--type=dataIf you need to run using localhost as your ES host:
docker run --net=host --rm -ti elasticdump/elasticsearch-dump \
--input=http://staging.es.com:9200/my_index \
--output=http://localhost:9200/my_index \
--type=dataThe file format generated by this tool is line-delimited JSON files. The dump file itself is not valid JSON, but each line is. We do this so that dumpfiles can be streamed and appended without worrying about whole-file parser integrety.
For example, if you wanted to parse every line, you could do:
while read LINE; do jsonlint-py "${LINE}" ; done < dump.data.json
elasticdump: Import and export tools for elasticsearch
version: %%version%%

(default: 5)
--carryoverConcurrencyCount
If true, any incomplete requests from a <concurrencyInterval> will be carried over to
the next interval, effectively reducing the number of new requests that can be created
in that next interval. If false, up to <intervalCap> requests can be created in the
next interval regardless of the number of incomplete requests from the previous interval.
(default: true)
--throttleInterval
Delay in milliseconds between getting data from an inputTransport and sending it to an
outputTransport.

(default: data, options: [settings, analyzer, data, mapping, policy, alias, template, component_template, index_template])
--filterSystemTemplates
Whether to remove metrics-*-* and logs-*-* system templates
(default: true])
--templateRegex
Regex used to filter templates before passing to the output transport
(default: ((metrics|logs|\\..+)(-.+)?)
--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 values are
if ES > 5
`'{"query": { "match_all": {} }, "stored_fields": ["*"], "_source": true }'`
else
`'{"query": { "match_all": {} }, "fields": ["*"], "_source": true }'`
[As of 6.68.0] If the searchBody is preceded by a @ symbol, elasticdump will perform a file lookup
in the location specified. NB: File must contain valid JSON
--searchWithTemplate
Enable to use Search Template when using --searchBody
If using Search Template then searchBody has to consist of "id" field and "params" objects
If "size" field is defined within Search Template, it will be overridden by --size parameter
See https://www.elastic.co/guide/en/elasticsearch/reference/current/search-template.html for
further information
(default: false)
--headers
Add custom headers to Elastisearch requests (helpful when
your Elasticsearch instance sits behind a proxy)
(default: '{"User-Agent": "elasticdump"}')
Type/direction based headers are supported .i.e. input-headers/output-headers
(these will only be added based on the current flow type input/output)
--params
Add custom parameters to Elastisearch requests uri. Helpful when you for example
want to use elasticsearch preference
--input-params is a specific params extension that can be used when fetching data with the scroll api
--output-params is a specific params extension that can be used when indexing data with the bulk index api
NB : These were added to avoid param pollution problems which occur when an input param is used in an output source
(default: null)

Normal: {"_index":"","_type":"","_id":"", "_source":{SOURCE}}
sourceOnly: {SOURCE}
(default: false)
--ignore-errors

This will allow dumps to be resumed used the last scroll Id &
`scrollTime` has not expired.
--scrollTime
Time the nodes will hold the requested search in order.
(default: 10m)
--scroll-with-post
Use a HTTP POST method to perform scrolling instead of the default GET
(default: false)
--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.
(default: 0)
--noRefresh
Disable input index refresh.
Positive:
1. Much increase index speed
2. Much less hardware requirements
Negative:
1. Recently added data may not be indexed
Recommended to use with big data indexing,
where speed and system health in a higher priority
than recently added data.
--inputTransport
Provide a custom js file to use as the input transport
--outputTransport
Provide a custom js file to use as the output transport
--toLog
When using a custom outputTransport, should log lines
be appended to the output stream?
(default: true, except for `$`)
--transform
A method/function which can be called to modify documents
before writing to a destination. A global variable 'doc'
is available.
Example script for computing a new field 'f2' as doubled
value of field 'f1':
doc._source["f2"] = doc._source.f1 * 2;
May be used multiple times.
Additionally, transform may be performed by a module. See [Module Transform](#module-transform) below.
--awsChain

This page
Elasticsearch provides a scroll API to fetch all documents of an index starting from (and keeping) a consistent snapshot in time, which we use under the hood. This method is safe to use for large exports since it will maintain the result set in cache for the given period of time.
NOTE: only works for --output
Set the environment NODE_TLS_REJECT_UNAUTHORIZED=0 before running elasticdump
# An alternative method of passing environment variables before execution
# NB : This only works with linux shells
NODE_TLS_REJECT_UNAUTHORIZED=0 elasticdump --input="https://localhost:9200" --output myfileThis package also ships with a second binary, multielasticdump. This is a wrapper for the normal elasticdump binary, which provides a limited option set, but will run elasticdump in parallel across many indexes at once. It runs a process which forks into n (default your running host's # of CPUs) subprocesses running elasticdump.
The limited option set includes:
parallel:os.cpus(),match:'^.*$',order:'asc',input:null,output:null,scrollTime:'10m',timeout:null,limit:100,offset:0,size:-1,direction:dump,ignoreType: ``includeType: ``prefix:'''suffix:''interval:1000searchbody:nulltransform:nullsupport-big-int:falsebig-int-fields: ``ignoreChildError:false
If the --direction is dump, which is the default, --input MUST be a URL for the base location of an ElasticSearch server (i.e. http://localhost:9200) and --output MUST be a directory. Each index that does match will have a data, mapping, and analyzer file created.
For loading files that you have dumped from multi-elasticsearch, --direction should be set to load, --input MUST be a directory of a multielasticsearch dump and --output MUST be a Elasticsearch server URL.
--parallel is how many forks should be run simultaneously and --match is used to filter which indexes should be dumped/loaded (regex).
--ignoreType allows a type to be ignored from the dump/load. Six options are supported. data,mapping,analyzer,alias,settings,template. Multi-type support is available, when used each type must be comma(,)-separated
and interval allows control over the interval for spawning a dump/load for a new index. For small indices this can be set to 0 to reduce delays and optimize performance
i.e analyzer,alias types are ignored by default
--includeType allows a type to be included in the dump/load. Six options are supported - data,mapping,analyzer,alias,settings,template.
ignoreChildError allows multi-elasticdump to continue if a child throws an error.
New options, --suffix allows you to add a suffix to the index name being created e.g. es6-${index} and
--prefix allows you to add a prefix to the index name e.g. ${index}-backup-2018-03-13.
--order accepts asc or desc and allows the indexes/aliases to be sorted before processing is performed
# backup ES indices & all their type to the es_backup folder
multielasticdump \
--direction=dump \
--match='^.*$' \
--input=http://production.es.com:9200 \
--output=/tmp/es_backup
# Only backup ES indices ending with a prefix of `-index` (match regex).
# Only the indices data will be backed up. All other types are ignored.
# NB: analyzer & alias types are ignored by default
multielasticdump \
--direction=dump \
--match='^.*-index$'\
--input=http://production.es.com:9200 \
--ignoreType='mapping,settings,template' \
--output=/tmp/es_backupWhen specifying the transform option, prefix the value with @ (a curl convention) to load the top-level function which is called with the document and the parsed arguments to the module.
Uses a pseudo-URL format to specify arguments to the module as follows. Given:
elasticdump --transform='@./transforms/my-transform?param1=value¶m2=another-value'
with a module at ./transforms/my-transform.js with the following:
module.exports = function (doc, options) {
// do something to doc
};
will load module ./transforms/my-transform.js', and execute the function with docandoptions={"param1": "value", "param2": "another-value"}`.
An example transform for anonymizing data on-the-fly can be found in the transforms folder.
Elasticdump is capable of reading/writing nested data, but in a _opinionated way. This is to reduce complexity while parsing/saving CSVs The format flattens all nesting to a single level (an example of this is shown below)
{
"elasticdump": {
"version": "6.51.0",
"formats": ["json", "csv"]
},
"contributors": [{
"name": "ferron",
"id": 3
}],
"year": 112
}Output format
{
"elasticdump": "{\"version\":\"6.51.0\",\"formats\":[\"json\",\"csv\"]}",
"contributors": "{\"contributors\":[{\"name\":\"ferron\",\"id\":3}]}",
"year": 2020
}Notice that the data is flattened to 1 level. Object keys are used for headers and values as row data.
This might not work with existing nested data formats, but that's the format that was chosen for elasticdump
because of its simplicity. This detection is disabled by default, to enable use the --csvHandleNestedData flag
- This tool is likely to require Elasticsearch version 1.0.0 or higher
- Elasticdump (and Elasticsearch in general) will create indices if they don't exist upon import
- When exporting from elasticsearch, you can export an entire index (
--input="http://localhost:9200/index") or a type of object from that index (--input="http://localhost:9200/index/type"). This requires ElasticSearch 1.2.0 or higher - If the path to our elasticsearch installation is in a sub-directory, the index and type must be provided with a separate argument (
--input="http://localhost:9200/sub/directory --input-index=index/type").Using--input-index=/will include all indices and types. - We can use the
putmethod to write objects. This means new objects will be created and old objects with the same ID be updated - The
filetransport will not overwrite any existing files by default, it will throw an exception if the file already exists. You can make use of--overwriteinstead. - If you need basic http auth, you can use it like this:
--input=http://name:password@production.es.com:9200/my_index - If you choose a stdio output (
--output=$), you can also request a more human-readable output with--format=human - If you choose a stdio output (
--output=$), all logging output will be suppressed - If you are using Elasticsearch version 6.0.0 or higher the
offsetparameter is no longer allowed in the scrollContext - ES 6.x.x & higher no longer support the
templateproperty for_template. All templates prior to ES 6.0 has to be upgraded to useindex_patterns - ES 7.x.x & higher no longer supports
typeproperty. All templates prior to ES 6.0 has to be upgraded to remove the type property - ES 5.x.x ignores offset (from) parameter in the search body. All records will be returned
