The first Seoul Elasticsearch meetup of 2016 took place on March 31 at Naver D2 Startup Factory in Gangnam, attracting around 130 attendees—nearly three times the usual number. The event featured several presentations, including a review of Elastic{on} 2016 and a demonstration of the new Graph feature in Elasticsearch 2.3.0 by Jongmin Kim, an auto-tagging system using Elasticsearch by Junyi Song from Melon, and a discussion on building search infrastructure in e-commerce by Ho-wook Jung from Memebox. Additionally, Geonbok Lee from Microsoft Korea demonstrated creating an Elasticsearch cluster using Microsoft Azure Marketplace, humorously engaging the audience with a nod to open-source by declaring "We love Linux." The meetup's popularity was evident as it quickly reached full capacity and topped the OnOffMix popularity rankings shortly after being announced. The event also marked the introduction of Elastic's new stickers in Korea and featured greetings from several key Elastic representatives, including Robert Lau, Chin Lian Heng, Matias Cascallares, and Hawon Jung.
