invenio-indexer

Indexer for Invenio.

Invenio-Indexer is responsible for sending records for indexing in Elasticsearch so that the records can be searched. Invenio-Indexer can either send the records in bulk or individually. Bulk indexing is far superior in performance if multiple records needs to be indexed at the price of delay. Bulk indexing works by queuing records in a message queue, which is then consumed and sent to Elasticsearch.
