Bridging the gap: achieving fast data synchronization from SAP HANA by leveraging Hadoop

Bridging the gap: achieving fast data synchronization from SAP HANA by leveraging Hadoop

Wednesday, June 20
4:00 PM - 4:40 PM
Executive Ballroom 210D/H

American Water will share the success story of American Water’s production use case of leveraging Hadoop and Streaming to ingest and supply de-normalized data from the source transactional systems to end-user applications. It covers the end-to-end flow and the challenges faced.

The data is de-normalized into single subject views at the source to eliminate complex join logic during ingestion into the data lake. Within the views, only timestamps on highly volatile tables have been exposed to give visibility to updates and inserts that have occurred on a table. NiFi ingests the data with a new processor and then stores it in ACID tables in Hive. The custom processor polls the timestamp columns, which generates paginated queries that consists of the delta.

American Water’s use case: Our field employees are our front line with our customers and in the past have felt unable to help customers effectively with our past technologies. One of the largest initiatives is to enable our field employees with accurate and up-to-date information via a new application so they can provide a great customer experience.
