In a discussion about his experience at Elastic{ON} Tour conferences and the integration of Elasticsearch into Yodle's Centermark product, Mark Drago highlights the journey and evolution of the platform's technical architecture. Initially relying on Hadoop for pre-aggregating metrics, Yodle faced challenges in providing flexibility to their customers, leading them to adopt Elasticsearch for its speed and efficiency in delivering business insights. Drago appreciates the collaborative environment of the conferences, where he gains insights into new features and engages with peers to enhance their product offerings. He candidly shares the trials and triumphs of building Centermark, a marketing automation platform for franchises, and notes the sense of atonement in publicly discussing the project's early shortcomings.
