Using Elasticsearch Connector with Ingest Node Pipeline

This post explores the use of Elasticsearch Connector 4.2 with Couchbase, a distributed JSON document database, to replicate and transform data from Couchbase to Elasticsearch using an Ingest node pipeline. The process involves installing and configuring Couchbase, Elasticsearch, Kibana, and the connector, building and deploying the pipeline, and verifying its functionality. The post assumes a basic understanding of these components and provides step-by-step instructions for replicating the travel-sample landmark dataset from Couchbase to Elasticsearch with transformations such as converting field values to uppercase and creating a new field with current date-time.
