Yandex with Elasticsearch can be used in a few different ways.
-
Yandex Cloud can be used for hosting Elasticsearch clusters. This allows users to store and manage data, while also providing access to the Elasticsearch API.
-
Yandex Machine Learning can be used to build machine learning models using the data stored in an Elasticsearch cluster. This can be used for applications such as natural language processing, anomaly detection, and more.
-
Yandex Search can be used to search through data stored in an Elasticsearch cluster. This can be used to quickly find relevant information within a large dataset.
Example code
# connect to Yandex Cloud
from yandex.cloud import Client
client = Client.from_service_account_file('/path/to/service_account.json')
# connect to Elasticsearch cluster
from elasticsearch import Elasticsearch
es = Elasticsearch(hosts=['host1', 'host2'], port=9200)
# search for data
res = es.search(index="myindex", body={"query": {"match_all": {}}})
print(res)
Output example
{'took': 2, 'timed_out': False, '_shards': {'total': 5, 'successful': 5, 'skipped': 0, 'failed': 0}, 'hits': {'total': {'value': 10, 'relation': 'eq'}, 'max_score': 1.0, 'hits': [{'_index': 'myindex', '_type': '_doc', '_id': '1', '_score': 1.0, '_source': {'field1': 'value1', 'field2': 'value2'}}, {'_index': 'myindex', '_type': '_doc', '_id': '2', '_score': 1.0, '_source': {'field1': 'value3', 'field2': 'value4'}}]}}
