To make critical business decisions in real time, many businesses today rely on a variety of data, which arrives in large volumes. Variety and volume together make big data applications complex operations. Big data applications require businesses to combine transactional data with structured, semi-structured, and unstructured data for deep and holistic insights.

And, time is of the essence: to derive the most valuable insights and drive key decisions, large amounts of data have to be continuously ingested into Hadoop data lakes as well as other destinations. As a result, data ingestion poses the first challenge for businesses, which must be overcome before embarking on data analysis.

With its various Application Templates for ingestion, DataTorrent allows users to:

Ingest vast amounts of data with enterprise-grade operability and performance guarantees provided by its underlying Apache Apex framework. Those guarantees include fault tolerance, linear scalability, high throughput, low latency, and end-to-end exactly-once processing.

Quickly launch template applications to ingest raw data, while also providing an easy and iterative way to add business logic and such processing logic as parse, dedupe, filter, transform, enrich, and more to ingestion pipelines.

Visualize various metrics on throughput, latency and app data in real-time throughout execution.

Template descriptions:

HDFS to Kafka: The HDFS to Kafka Application Template continuously reads lines from configured Hadoop HDFS file(s) and writes each line as a message in configured Apache Kafka topic.

Kafka to HDFS: The Kafka to HDFS Application Template continuously reads messages from configured Apache Kafka topic(s) and writes each message as a line in Hadoop HDFS file(s).
