Any application can use this system with simple message registration and start sending the data. Right now it collects about 12 million data points per minute at the peak and more than 4 billion messages/records per day. We process about 1 TB of data per day using this system and stored in HDFS. Built end to end scalable data pipelines / ETL to ingest data from different sources and process and transfer the data to various destinations using PIG, Hive, Sqoop and Oozie. Designed and implemented big data warehouse with nearly 1 PB of data using HDFS and Hive Designed and implemented backend systems for custom Ad exchange platform that servers more than 2 billion impressions per day using Couchbase. Designed and re-architected the scalable data platform based on distributed shared nothing architecture. This system currently runs on 4 nodes supporting 25 million daily active users and supports more than 100k transactions per second with 99.99% up time. It can be scalable up to 256 nodes.
