FabFunnel, developed by IdeaClan, is a digital marketing platform designed to streamline campaign management by integrating creative workflows, automation, and reporting from a single dashboard, with real-time data integration from major ad platforms like Facebook, TikTok, and Google. Initially launched at Affiliate World Budapest in 2025, the platform faced challenges with its MySQL-based architecture, which struggled to handle the high volume of real-time data necessary for efficient marketing analytics. To address these issues, FabFunnel transitioned to ClickHouse Cloud, a decision that significantly enhanced system performance by enabling fast, high-volume data inserts and sub-second query responses, thanks to features like Confluent Kafka for data ingestion, ReplacingMergeTree tables for real-time updates, and refreshable materialized views for efficient data aggregation. This migration not only improved query efficiency and reduced infrastructure overhead but also allowed FabFunnel to deliver instant analytics, enabling media buyers to manage and scale campaigns effectively without infrastructure constraints.
