Large-scale Infrastructure Engineer on data storage service
(ZippyDB) and Monitoring systems teams.
</p>
<ul>
<li class="li-major">
Data Infrastructure: Worked on ZippyDB, a distributed and replicated
key-value store based on Paxos and RocksDB. Helped port the
real-time counter service (unique counters based on HyperLogLog) to
ZippyDB (with live customers) and migrated it to Folly Futures for
our C++ APIs. Implemented the first production version of the shard
load balancer, which enabled balancing on several metrics across
possibly heterogeneous hardware.

<li class="li-major">
Core Infrastructure: Monitoring Systems: Moved the backend operating
metrics and monitoring systems from a MySQL backend to HBase, and
worked on Disaster Recovery. Worked on many of the subsystems such
as real-time percentile aggregation, prediction modeling, and the
real-time computation engine. System processed over 1 Billion time
series datapoints per minute at the time I left the team.

Inside Data@Scale 2015 (ZippyDB overview)
https://code.facebook.com/posts/371721473024046/inside-data-scale-2015/
(See embedded video) Muthu Annamalai from Facebook spoke about
ZippyDB, a highly reliable key/value memory cache service used by
many Facebook services. Annamalai spoke about the architecture of
ZippyDB, the additional services built on top to make it even more
useful beyond a traditional key-value store. This makes it ideal to
serve the varied needs of Facebook's applications. He also discussed
ZippyDB's ability to give application services tight control over
data placement
Facebook’s Large Scale Monitoring System Built on HBase: Strata Conference + Hadoop World 2012
http://conferences.oreilly.com/strata/stratany2012/public/schedule/speaker/146356
ODS is Facebook’s internal monitoring system, which collects a variety of system and application level metrics from every server for real-time monitoring, anomaly detection, alerting and analysis.
In this talk, we’ll start by giving an overview of ODS, and go over
the manageability and scalability challenges with the previous MySQL
based setup. We will then discuss our motivation to choose HBase for
this workload, and share a series of lessons learnt from building
ODS on top of HBase, [...]
