Pelias Elasticsearch database client

This module provides a Node.js stream for bulk-inserting documents into Elasticsearch.


Install Dependencies

``bash
$ npm install
`

Usage


`javascript
'use strict';

// some_importer.js

const streamify = require('stream-array');
const through = require('through2');
const Document = require('pelias-model').Document;
const dbMapper = require('pelias-model').createDocumentMapperStream;
const dbclient = require('pelias-dbclient');

const elasticsearch = require('elasticsearch');
const config = require('pelias-config').generate();
const elasticDeleteQuery = require('elastic-deletebyquery');

const timestamp = Date.now();

const stream = streamify([1, 2, 3])
.pipe(through.obj((item, enc, next) => {
const uniqueId = [ 'docType', item ].join(':'); // documents with the same id will be updated
const doc = new Document( 'sourceType', 'venue', uniqueId );
doc.timestamp = timestamp;
next(null, doc);
}))
.pipe(dbMapper())
.pipe(dbclient()); // put documents into elasticsearch

stream.on('finish', () => {
const client = new elasticsearch.Client(config.esclient);
elasticDeleteQuery(client);

const options = {
index: config.schema.indexName,
body: {
query: {
"bool": {
"must": [
{"term": { "source": "sourceType" }}
],
"must_not": [
{"term": { "timestamp": timestamp }}
]
}
}
}
};

client.deleteByQuery(options, (err, response) => {
console.log('The elements deleted are: %s', response.elements);
});
});
