Issue Tracker

This project is maintained in the spare time of contributors and so time able to be dedicated to it is extremely limited.

Please file issues only for reproducable problems. Given our limited time, we are not able to provide any help using the river and issues that simply say "things aren't working" will be closed. However, if you're able to diagnose an issue yourself we may be able to help with a fix and we are happy to review pull requests.

To debug issues, try changing the log level to trace as described in the wiki. You may wish to build a custom version of the river with extra logging.

MongoDB River Plugin for ElasticSearch

This plugin uses MongoDB or the TokuMX fork of MongoDB as datasource to store data in ElasticSearch. Filtering and transformation are also possible. See the wiki for more details.

In order to install the plugin, simply run: bin/plugin --install com.github.richardwilly98.elasticsearch/elasticsearch-river-mongodb/2.0.7

Note that you must be using MongoDB replica sets since this river tails the oplog.

Build Status

Initial implementation by aparo.

Modified to get the same structure as the other Elasticsearch rivers (like CouchDB)

The latest version monitors the oplog capped collection and supports attachment (GridFS).

Configure the river using the definition described in the wiki:

  curl -XPUT 'http://localhost:9200/_river/mongodb/_meta' -d '{
    "type": "mongodb", 
    "mongodb": { 
      "db": "DATABASE_NAME", 
      "collection": "COLLECTION", 
      "gridfs": true
    }, 
    "index": { 
      "name": "ES_INDEX_NAME", 
      "type": "ES_TYPE_NAME" 
    }
  }'

Example:

  curl -XPUT 'http://localhost:9200/_river/mongodb/_meta' -d '{ 
    "type": "mongodb", 
    "mongodb": { 
      "db": "testmongo", 
      "collection": "person"
    }, 
    "index": {
      "name": "mongoindex", 
      "type": "person" 
    }
  }'

Import data from mongo console:

  use testmongo
  var p = {firstName: "John", lastName: "Doe"}
  db.person.save(p)

Query index:

  curl -XGET 'http://localhost:9200/mongoindex/_search?q=firstName:John'
  curl -XPUT 'http://localhost:9200/_river/mongodb/_meta' -d '{ 
    "type": "mongodb", 
    "mongodb": { 
      "db": "testmongo", 
      "collection": "fs", 
      "gridfs": true 
    }, 
    "index": {
      "name": "mongoindex", 
      "type": "files" 
    }
  }'

Import binary content in mongo:

  %MONGO_HOME%\bin>mongofiles.exe --host localhost:27017 --db testmongo --collection fs put test-document-2.pdf
  connected to: localhost:27017
  added file: { _id: ObjectId('4f230588a7da6e94984d88a1'), filename: "test-document-2.pdf", chunkSize: 262144, uploadDate: new Date(1327695240206), md5: "c2f251205576566826f86cd969158f24", length: 173293 }
  done!

Query index:

  curl -XGET 'http://localhost:9200/files/4f230588a7da6e94984d88a1?pretty=true'
