Nirmal Chidambaram works as Software Architect at CS DISCO where he makes sure e-Discovery search infrastructure stays healthy ( In case you are wondering whats e-Discovery - thats how lawyers search thru millons /billions of documents / patents related a litigations to produce evidence or identify supporting materials). Previously he worked at Bazaarvoice , Atlassian and Dell . Elasticsearch clusters he supported ranges from few thousands of documents to billions of documents in count ; queries range from few chars to few megabytes ; query traffic ranges from once_in_a_while to several thousands per second. In addition to designing and supporting elastic search infrastructure , he also patches/customizes elastic search ( plugins whenever it is possible) in case of a custom feature or if it can’t wait till next version.
