I'm going to comment for Elasticsearch as that is the tag used for this question.
You can:
<ul>
<li>Read from the database (<code>SELECT * from TABLE</code>)</li>
<li>Convert each record to a JSON Document</li>
<li>Send the json document to elasticsearch, preferably using the <code>_bulk</code> API.</li>
</ul>
Logstash can help for that. But I'd recommend modifying the application layer if possible and send data to elasticsearch in the same &quot;transaction&quot; as you are sending your data to the database.
I shared most of my thoughts there: <a href="http://david.pilato.fr/blog/2015/05/09/advanced-search-for-your-legacy-application/" rel="nofollow noreferrer">http://david.pilato.fr/blog/2015/05/09/advanced-search-for-your-legacy-application/</a>

Side note: If you want to run Elasticsearch, have look at <a href="https://www.elastic.co/cloud" rel="nofollow noreferrer">Cloud by Elastic</a>, also available if needed from <a href="https://aws.amazon.com/marketplace/pp/Elasticsearch-Inc-Elasticsearch-Service-on-Elastic/B01N6YCISK" rel="nofollow noreferrer">AWS Marketplace</a>, <a href="https://azuremarketplace.microsoft.com/en-us/marketplace/apps/elastic.ec-azure?tab=Overview" rel="nofollow noreferrer">Azure Marketplace</a> and <a href="https://console.cloud.google.com/marketplace/details/endpoints/elasticsearch-service.gcpmarketplace.elastic.co" rel="nofollow noreferrer">Google Cloud Marketplace</a>.
Cloud by elastic is one way to have access to all features, all managed by us. Think about what is there yet like Security, Monitoring, Reporting, SQL, Canvas, Maps UI, Alerting and built-in solutions named <a href="https://www.elastic.co/observability" rel="nofollow noreferrer">Observability</a>, <a href="https://www.elastic.co/security" rel="nofollow noreferrer">Security</a>, <a href="https://www.elastic.co/enterprise-search" rel="nofollow noreferrer">Enterprise Search</a> and what is coming next :) ...

Keep a column that indicates when the row was last modified, then you will be able to do updates to OpenSearch. Similarly for deleting, just have a column indicating whether it is deleted or not (soft delete), and the date it was deleted.
With this db design, you can send the &quot;delete&quot; or &quot;update&quot; actions to OpenSearch/ElasticSearch to update/delete the indexes based on the last modified / deleted date. You can later have a scheduled maintenance job to delete these rows permanently from the database table.
Lastly, this article might be of help to you <a href="https://www.elastic.co/blog/how-to-keep-elasticsearch-synchronized-with-a-relational-database-using-logstash" rel="nofollow noreferrer">How to keep Elasticsearch synchronized with a relational database using Logstash and JDBC</a>

I am new to Amazon OpenSearch service, and i wish to know if there's anyway i can sync MySQL db with Opensearch on real time. I thought of Logstash but it seems like it doesn't support delete , update operations which might not update my OpenSearch cluster

我是亚马逊OpenSearch服务的新手，我想知道有没有什么方法可以让MySQL数据库与Opensearch实时同步。我想到了Logstash，但它似乎不支持删除、更新操作，这些操作可能不会更新我的OpenSearch集群
