Modernizing insurance BI on Databricks and Delta Lake

A legacy SSIS and SQL stack could not carry 100M rows a day. Algoscale replaced it with a schema-resilient Delta Lake pipeline feeding Azure Synapse and Power BI.

About the Company.

A prominent U.S.-based insurance provider serving millions of policyholders. The organization operates at scale across policy issuance, claims processing, and regulatory reporting functions.

50%Improvement in data throughput — scaled from 100M to 150M rows/day
87.5%Faster ETL pipeline — reduced from 4 hours to 30 minutes
83%Improvement in data latency — insights available in under 1 hour
82%Reduction in Power BI refresh time — from 45 min to 8 min
5Xgrowth in active analysts — supported from 10 to 50 concurrent users
40%reduction in monthly compute costs — optimized with auto-scaling Spark clusters

Solution Summary.

The client needed to modernize its reporting infrastructure to handle growing data volumes and improve agility across analytics functions. Algoscale designed and implemented a modern ETL architecture on Databricks, replacing the legacy stack with a scalable, schema-resilient pipeline. We leveraged Delta Lake for reliability, enabled auto-scaling compute for efficiency, and integrated with Azure Synapse and Power BI for real-time reporting capabilities.

Customer Challenges.

The client faced multiple operational and technical bottlenecks with its legacy SSIS/SQL-based reporting workflows. These included poor scalability for high-volume data loads, frequent pipeline failures due to rigid schema handling, and long data refresh cycles that delayed access to critical insights. The over-provisioned compute infrastructure further contributed to inefficiencies and high operational costs.

  • High Volume, Low Throughput.

    Existing workflows couldn’t reliably process 100M+ rows/day, leading to frequent data lags.
  • Delayed Reporting & Insights.

    Latencies over 6 hours delayed KPIs related to claims, finances, and risk dashboards.
  • Brittle Pipelines.

    Frequent schema changes broke the ETL, requiring manual fixes and increasing downtime.
  • Poor Collaboration.

    On-prem SQL infrastructure lacked elasticity, leading to over-provisioned compute and higher costs.
  • Limited Scalability.

    Fragmented development between engineers and analysts caused delays and misalignment.

Algoscale Solution.

Algoscale engineered a scalable, cloud-native data platform using Databricks and Delta Lake to drive end-to-end automation, reliability, and performance.

  • Ingestion Modernization.

    Ingested raw CSV/Parquet data from Azure Data Lake Gen2 using mounted paths into Databricks.
  • Delta Lake Architecture.

    Implemented Bronze → Silver → Gold architecture using Delta Lake with schema enforcement, ACID transactions, and time-travel.
  • Dynamic Schema Handling.

    Enabled schema evolution to handle changes without breaking jobs—removing manual effort.
  • Real-Time Consumption.

    Published Gold tables to Azure Synapse, enabling near real-time Power BI dashboards.
  • Dev & Analyst Collaboration.

    Leveraged shared Databricks notebooks to reduce back-and-forth and accelerate delivery
  • Cost-Efficient Processing.

    Used auto-scaling clusters to optimize batch load times while trimming infrastructure costs.

Algoscale Differentiators.

  • Metadata-Driven XML Parsing.

    Dynamic ingestion framework powered by centralized schema registries enabled seamless handling of complex and evolving XML structures across multiple regions.
  • End-to-End Delta Lake Governance.

    Leveraged Delta Lake features like schema enforcement, ACID transactions, and time travel for reliable, auditable data pipelines with zero manual intervention during schema changes.
  • Native Power BI Integration via Synapse.

    Published curated Gold-layer datasets to Azure Synapse, ensuring fast, reliable connectivity to Power BI dashboards for real-time, business-ready analytics.
  • Auto-Scaling Cluster Architecture.

    Implemented compute clusters with auto-scaling policies to optimize resource utilization—supporting peak batch loads without over-provisioning.
  • Collaborative Development Ecosystem.

    Enabled seamless iteration between data engineers and analysts through shared Databricks notebooks and version-controlled development flows.
