The value of data can be maximised when it is used without delay. With Apache Flink, we can build streaming analytics applications that incorporate the latest events with low latency. In this lab, we will create a Pyflink application that writes accumulated taxi rides data into an OpenSearch cluster. It aggregates the number of trips/passengers and trip durations by vendor ID for a window of 5 seconds. The data is then used to create a chart that monitors the status of taxi rides in the OpenSearch Dashboard.

Kafka Connect can be an effective tool to ingest data from Apache Kafka into OpenSearch. In this post, we will discuss how to develop a data pipeline from Apache Kafka into OpenSearch locally using Docker while the pipeline will be deployed on AWS in the next post. Fake impressions and clicks data will be pushed into Kafka topics using a Kafka source connector and those records will be ingested into OpenSearch indexes using a sink connector for near-real time analytics.
