Improved last-mile supply chain analytics for a pharmacy chain by migrating to AWS.

Retail pharmacy and wellness · 24x7 network

SQL Server and PowerBI could not carry 1.5TB of sales history across 250+ tables. We built the warehouse underneath it.

The opportunity

A catalogue of 100,000+ products, and no single place to analyse it.

This omnichannel pharmacy chain runs a hyperlocal network of 24x7 stores carrying over 100,000 products. Its analytics ran on SQL Server and PowerBI-a combination that was expensive and limited in what it could actually compute.

The data was not consolidated, so large-scale analysis meant working across sources. And the setup was inadequate for the workload: 1.5TB of historical sales data, 1GB arriving incrementally, across more than 250 tables. Sales and inventory decisions were made without the picture they needed.

SQL Server and PowerBI at cost

The incumbent stack was expensive and analytically limited.

Data was not consolidated

No single source meant large-scale analysis worked across systems.

Inadequate for the workload

1.5TB historical, 1GB incremental, 250+ tables exceeded what the setup could carry.

Decisions made without the picture

Sales and inventory choices lacked the analysis to inform them.

The impact

Six hours of processing became thirty minutes.

  • Redshift as the warehouse

    A scalable warehouse designed for complex analytics replaced a database being used as one.

  • ETL across every source

    A pipeline extracts, transforms for consistency and loads from the disparate systems into one place.

  • PowerBI kept, repointed

    The existing reporting tool now queries Redshift, so the team's dashboards did not have to be relearned.

  • Queries optimised

    Workflow and query tuning is what took processing time from six hours to thirty minutes.

The road ahead

The warehouse is in. Next is what runs on it.

With consolidated data and optimised processing, the same foundation supports ML models and dynamic reporting across sources that previously could not be analysed together.
