![]() However, for drops the namespace is the database name and the string $cmd joined by a dot. Like the other types of changes this event has a field ns representing the namespace. When a database or collection is dropped in MongoDB an event is appended to the oplog. In addition to inserts, updates, and deletes monstache also supports database and collection drops. curl -H "Content-Type:application/json" localhost:9200/users.fs.files/_search?pretty -d ') the namespace for the event in the oplog would be test.foo. mongofiles -d users put resume.docxĪfter a short time you should be able to query the contents of resume.docx in the users index in Elasticsearch curl -XGET " If you would like to see the text extracted by Apache Tika you can project the appropriate sub-fieldįor Elasticsearch versions prior to version 5. Continuing the example above one could issue the following command to put aįile named resume.docx into GridFS and after a short time this file should be searchable in Elasticsearch in the index users.fs.files. To test this feature of monstache you can simply use the mongofilesĬommand to quickly add a file to MongoDB via GridFS. The Elasticsearch plugin will then extract text content from the raw content usingĪpache Tika, tokenize the text content, and allow you to query on the content of the file. ![]() When a file is inserted into MongoDB via GridFS, monstache will detect the new file, use the MongoDB api to retrieve the rawĬontent, and index a document into Elasticsearch with the raw content stored in a file field as a base64Įncoded string. "description" : "Extract file information", POST /users.fs.filesįor Elasticsearch version 5 and above. When you configure monstache this way it will perform an additional operation at startup to ensure the destination indexes inĮlasticsearch have a field named file with a type mapping of attachment.įor the example TOML configuration above, monstache would initialize 2 indices in preparation for indexing intoĮlasticsearch by issuing the following REST commands:įor Elasticsearch versions prior to version 5. However, if you have customized the bucket name, then your file collection would be something like mybucket.filesĪnd the entire namespace would be. By default, MongoDB uses a bucket named fs, so if you just use the defaults your collection name willīe fs.files. The above configuration tells monstache that you wish to index the raw content of GridFS files in the users and posts For example in your TOML config file, index-files = trueĭirect-read-namespaces = įile-namespaces = Namespace of all collections which will hold GridFS files. You will want to enable the index-files option and also tell monstache the ![]() Once you have installed the appropriate plugin for Elasticsearch, getting file content from GridFS into Elasticsearch isĪs simple as configuring monstache. This feature requires that you install an Elasticsearch plugin which enables the field type attachment.įor versions of Elasticsearch prior to version 5 you should install theįor version 5 or later of Elasticsearch you should instead install the Monstache supports indexing the raw content of files stored in GridFS into Elasticsearch for full Sometimes there are reasons to stay at a lower feature compatibility This sometimes happens when MongoDB is upgraded in place or MongoDB is started with a dataĭirectory of a previous installation. Your feature compatibility version from the MongoDB console to ensure that MongoDB is not operating in a lesserĬapability mode. Your MongoDB binary version does not always mean that the
