Distributed system::
Drill— Apache Drill is a distributed system for interactive analysis of large-scale datasets. Drill is similar to Google’s Dremel, with the additional flexibility needed to support a broader range of query languages, data formats and data sources. It is designed to efficiently process nested data. It is a design goal to scale to 10,000 servers or more and to be able to process petabyes of data and trillions of records in seconds.
Many organizations have the need to run data-intensive applications, including batch processing, stream processing and interactive analysis. In recent years open source systems have emerged to address the need for scalable batch processing (Apache Hadoop) and stream processing (Storm, Apache S4). In 2010 Google published a paper called “Dremel: Interactive Analysis of Web-Scale Datasets,” describing a scalable system used internally for interactive analysis of nested data. No open source project has successfully replicated the capabilities of Dremel.
