• [Award] September, 2018. Congratulations to Xingda Wei on winning the 2018 Microsoft Research Asia Fellowship Award! Only 11 Ph.D students got this prestigious fellows among 102 distinguished Ph.D. candidates from 40 leading research universities/institutions.

IDAS, the IPADS Data Analytics Stack, is an open source software stack that targets new heterogenous hardware features (e.g., RDMA, HTM, NVM, and GPU) and integrates software components being built by the IPADS to make sense of distributed in-memory transaction and analytical processing over big data. As shown in our architecture figure below, IDAS consists of a storage layer (key-value store and file system), an engine layer (transaction engine and analytics engine), and a batch of optimizations (from availability, durability, and concurrency to streaming processing, reconfiguration, and load balance).

You can use git clone or just download zip archive to get the codes

The source code of IDAS is available at IPADS's gitlab
