Empowering Personalised Banking Experiences | Databricks Weblog


At Zafin, our mission is to assist banks modernize their core infrastructure to ship distinctive, personalised experiences to their prospects. To find out buyer relationship tiers and supply personalised rewards, we would have liked to course of important information volumes—100 million accounts with over 10 billion balances. Historically, we might have carried out this tiering software utilizing an open-source framework, Java Spring Boot, with a devoted PostgreSQL server. Nonetheless, constructing and scaling this answer with a standard tech stack proved inefficient and unsustainable at scale.

Conventional information infrastructure doesn’t scale

Like many organizations in monetary companies, we initially relied on devoted information warehousing options to energy our analytics. Whereas useful, this strategy got here with important challenges: excessive compute prices, upkeep overhead, and efficiency bottlenecks.

With a single-tenant structure, each buyer deployment requires devoted infrastructure. Since some prospects use analytics sporadically whereas others depend on it actively, this setup was costly and inefficient. Devoted infrastructure demanded fixed fine-tuning and incurred fastened prices, no matter utilization—a big effort for our engineering groups. Scaling to accommodate huge information volumes throughout tens of millions of accounts, balances, and transactions typically stretched our conventional programs to their limits.

Advanced computations, similar to processing billions of information for buyer segmentation, tiering, and analyzing relationship patterns, ran as batch jobs that had been sluggish to finish. These bottlenecks delayed time-to-insight, and our conventional strategy couldn’t sustain with the size and pace banks required.

To seamlessly present superior analytics to our prospects, we would have liked an economical, scalable platform able to dealing with huge information volumes, delivering excessive efficiency, and maintaining prices beneath management.

Migrating to Databricks to speed up information intelligence

We ran a proof of idea (POC) to match our earlier Java Spring Boot/PostgreSQL setup with the Databricks Knowledge Intelligence Platform. Right here’s how the POC empowered us to enhance our information infrastructure.

Databricks delivered as much as 10x sooner computation speeds in comparison with our earlier answer. For instance, duties that beforehand took 4,000 seconds on our earlier system are actually accomplished in simply 300 seconds. With elastic scalability, we will course of billions of transactions and balances throughout tens of millions of accounts with out compromising efficiency.

Migrating analytics workflows lowered time-to-market for brand new capabilities by 30–40% whereas requiring fewer engineering sources. In comparison with our conventional setup, Databricks helped us speed up the supply timeline of our tiering software by 30%. With much less effort spent on infrastructure administration, our engineering crew can concentrate on constructing modern options for our prospects.

Databricks’ Serverless capabilities had been a sport changer, permitting us to separate compute from storage to make sure we solely paid for the compute we would have liked. This strategy eradicated the fee burden of idle infrastructure. Cloud prices for analytics dropped by 50–70%, relying on utilization profiles. The flexibility to auto-scale primarily based on information hundreds meant that each high-traffic and sporadic-use prospects may depend on a seamless, responsive expertise with out handbook tuning.

The outcomes had been clear: Databricks provided a transformative answer that delivered superior efficiency, scalability, and cost-efficiency—all whereas assembly the stringent governance necessities of extremely regulated monetary establishments.

Delivering worth to our prospects
