Description

Scrapy pipeline which allows you to store scrapy items in Elastic Search.

Install

pip install ScrapyElasticSearch

If you need support for ntlm:
pip install "ScrapyElasticSearch[extras]"

Usage (Configure settings.py:)

ITEM_PIPELINES = {
    'scrapyelasticsearch.scrapyelasticsearch.ElasticSearchPipeline': 500
}

ELASTICSEARCH_SERVERS = ['localhost']
ELASTICSEARCH_INDEX = 'scrapy'
ELASTICSEARCH_INDEX_DATE_FORMAT = '%Y-%m'
ELASTICSEARCH_TYPE = 'items'
ELASTICSEARCH_UNIQ_KEY = 'url'  # Custom unique key

# can also accept a list of fields if need a composite key
ELASTICSEARCH_UNIQ_KEY = ['url', 'id']

ELASTICSEARCH_SERVERS - list of hosts or string (single host). Host format: protocol://username:password@host:port.

Examples:

Available parameters (in settings.py)

 ELASTICSEARCH_INDEX - elastic search index
 ELASTICSEARCH_INDEX_DATE_FORMAT - the format for date suffix for the index, see python datetime.strftime for format. Default is no date suffix.
 ELASTICSEARCH_TYPE - elastic search type
 ELASTICSEARCH_UNIQ_KEY - optional field, unique key in string (must be a field or a list declared in model, see items.py)
 ELASTICSEARCH_BUFFER_LENGTH - optional field, number of items to be processed during each bulk insertion to Elasticsearch. Default size is 500.
 ELASTICSEARCH_AUTH  - optional field, set to 'NTLM' to use NTLM authentification
 ELASTICSEARCH_USERNAME - optional field, set to 'DOMAIN\username', only used with NLTM authentification
 ELASTICSEARCH_PASSWORD - optional field, set to your 'password', only used with NLTM authentification

 ELASTICSEARCH_CA - optional settings to if es servers require custom CA files.
 Example:
 ELASTICSEARCH_CA = {
      'CA_CERT': '/path/to/cacert.pem',
      'CLIENT_CERT': '/path/to/client_cert.pem',
      'CLIENT_KEY': '/path/to/client_key.pem'
