KakaoBank, a South Korean digital bank, leverages Imply's Apache Druid and Pivot for advanced financial analytics to handle the vast amounts of data generated by its mobile-first platform. The bank, known for transforming traditional banking with its seamless services, uses Imply to tackle challenges associated with high data resolution and concurrency in financial data analysis. This system allows for the processing of numerous ad-hoc queries on massive datasets, enhancing the bank's ability to analyze transactional trends at a granular level. Previously reliant on formalized procedures for data requests, KakaoBank's adoption of Imply has enabled more dynamic and interactive data visualizations, reducing the workload for data analysts and empowering business users to conduct independent analyses. As a result, the bank aims to broaden the use of Imply across its organization to foster a deeper understanding of financial data, ultimately gaining a competitive advantage through improved analytical capabilities and data comprehension.
