Research

•    Message Futures : Multi-Datacenter Replication - UCSB

- Developed a Multi-Datacenter Replication system which had a strongly consistent concurrency control manager with low commit latency to ensure 
  mutual consistency of replicas across datacenters.
- Matrix clocks were used to maintain synchronization among replicas.

•    TOPCOP : TwO Phase Commit Over Paxos (Spanner)  - UCSB    
- Built a distributed storage system to carry out transactions in a consistent manner.
- To strike a balance between consistency and availability in a distributed environment, Two Phase Commit protocol was merged with Paxos consensus algorithm.

•    C-SyTS : Cloud based multi-tasking System for Task Scheduling - UCSB
- Designed a feature rich pluggable task scheduler that could be deployed in a Cloud based Multitasking System.
- Dynamic scale up or scale down of nodes based on resource usage (Auto-scaling).

•    GEMS : Gossip-Enabled Monitoring Service for Heterogeneous Distributed Systems - UCSB
- GEMS is a highly responsive and scalable resource monitoring service, to monitor the liveness of nodes in a heterogeneous distributed systems and 
  to achieve consensus in a distributed environment.

•    K-NN based Music Recommendation System – UCSB 
- Developed a music recommendation system which recommends songs for a user based on user’s    behavior. K nearest neighborhood approach is followed 
  as a collaborative filtering algorithm to find nearest neighbors for the item in context.
