Case Research: How Dimona Constructed a Actual-Time Stock Administration System on Rockset
At Dimona, a number one Latin American attire firm based 55 years in the past in Brazil, our enterprise is t-shirts. We design them, manufacture them, and promote them to shoppers on-line and thru our 5 retail shops in Rio de Janeiro. We additionally provide B2B corporations for his or her clients in Brazil and the US.
We’ve come a great distance since 2011 after I joined Dimona to launch our first web site. In the present day, our API permits our B2B clients to add {custom} designs, and robotically route orders from their e-commerce websites to us. We then make the shirts on demand and ship them in as little as 24 hours.
Each APIs and fast-turnaround drop transport have been main improvements for the Latin American attire business, and it enabled us to develop in a short time. In the present day, we now have greater than 80,000 B2B clients equipped by our factories in Rio de Janeiro and South Florida. We are able to dropship on behalf of our B2B clients anyplace in Brazil and the U.S. and assist them keep away from the trouble and price of import taxes.
Our enterprise is flourishing. Nonetheless, we nearly didn’t get right here on account of rising pains with our knowledge know-how.
Off-the-Shelf ERP Programs Too Restricted
Attributable to our vertically-integrated enterprise mannequin, our provide chain is longer than most clothes makers. We have to monitor uncooked cloth because it arrives in our factories, the t-shirts as they transfer by way of the chopping, stitching and printing phases, and the completed merchandise as they journey from manufacturing facility to warehouse to retail retailer or mail provider earlier than lastly reaching clients.
Not solely is our provide chain longer than regular, so is the scale and variety of our stock. We’ve as much as a million t-shirts in inventory relying on the season. And as a result of many {custom} designs, colours, materials and sizes that we provide, the variety of distinctive gadgets can be increased than different attire makers.
We tried many off-the-shelf ERP methods to handle our stock end-to-end however nothing proved as much as the duty. Particularly, limitations in these methods meant we might solely retailer the end-of-day stock counts by location, fairly than a full document of every particular person merchandise because it traveled by way of our provide chain.
Monitoring solely stock counts minimized the quantity of information we needed to retailer. Nonetheless, it additionally meant that after we tried to check these counts with the stock actions we did have on file, mysterious errors emerged that we couldn’t reconcile. That made it laborious for us to belief our personal stock knowledge.
MySQL Crumbles Underneath Analytic Load
In 2019, we deployed our personal custom-built stock administration system to our foremost warehouse in Rio de Janeiro. Having had expertise with AWS, we constructed our stock administration system round Amazon Aurora, AWS’s model of MySQL-as-a-service. Relatively than simply document end-of-day stock totals, we recorded each stock motion utilizing three items of information: the merchandise ID, its location ID, and the amount of that merchandise at that location.
In different phrases, we created a ledger that tracked each t-shirt because it moved from uncooked cloth to completed items into the palms of a buyer. Each single barcode scan was recorded, whether or not it was a pallet of t-shirts shipped from the warehouse to a retailer, or a single shirt moved from one retailer shelf to a different.
This created an explosion within the quantity of information we have been gathering in actual time. Immediately, we have been importing 300,000 transactions to Aurora each two weeks. Nevertheless it additionally enabled us to question our knowledge to find the precise location of a specific t-shirt at any given time, in addition to view high-level stock totals and tendencies.
At first, Aurora was in a position to deal with the duty of each storing and aggregating the information. However as we introduced extra warehouses and shops on-line, the database began bogging down on the analytics facet. Queries that used to take tens of seconds began taking greater than a minute or timing out altogether. After a reboot, the system can be positive for a short time earlier than changing into sluggish and unresponsive once more.
Pandemic-Led Growth
Compounding the problem was the COVID-19’s arrival in early 2020. Immediately we had many worldwide clients clamoring for a similar drop cargo providers we offered in Brazil in different markets. In mid-2020, I moved to Florida and opened our U.S. manufacturing facility and warehouse.
By that time, our stock administration system had slowed all the way down to the purpose of being unusable. And our payments from doing even easy aggregations in Aurora have been by way of the roof.
We have been confronted with a number of choices. Going again to an error-ridden inventory-count system was out of the query. An alternative choice was to proceed recording all stock actions however use them solely to double-check our separately-tracked stock counts, fairly than producing our stock totals from the motion data themselves. That will keep away from overtaxing the Aurora database’s meager analytical capabilities. However it will power us to take care of two separate datasets – datasets that must be always in contrast towards one another with no assure that it will enhance accuracy.
We would have liked a greater know-how resolution, one that would retailer large knowledge units and question them in quick, automated methods in addition to make fast, easy knowledge aggregations. And we would have liked it quickly.
Discovering Our Resolution
I checked out a number of disparate choices. I thought of a blockchain-based system for our ledger earlier than shortly dismissing it. Inside AWS, I checked out DynamoDB in addition to one other ledger database supplied by Amazon. We couldn’t get DynamoDB to ingest our knowledge, whereas the ledger database was too uncooked and would have required an excessive amount of DIY effort to make work. I additionally checked out Elasticsearch, and got here to the identical conclusion – an excessive amount of {custom} engineering effort to deploy.
I realized about Rockset from an organization that additionally was seeking to substitute query-challenged Aurora with a quicker managed cloud different.
It took us simply two months to check and validate Rockset earlier than deploying it in September 2021. We continued to ingest all of our stock transactions into Aurora. However utilizing Amazon’s Database Migration Service (DMS), we now constantly replicate knowledge from Aurora into Rockset, which does all the knowledge processing, aggregations and calculations.
“The place Rockset actually shines is its skill to ship exact, correct views of our stock in near-real time.”

This connection was extraordinarily straightforward to arrange on account of Rockset’s integration with MySQL. And it’s quick: DMS replicates updates from a million+ Aurora paperwork to Rockset each minute, changing into accessible to customers immediately.
The place Rockset actually shines is its skill to ship exact, correct views of our stock in near-real time. We use Rockset’s Question Lambda functionality to pre-create named, parameterized SQL queries that may be executed from a REST endpoint. This avoids having to make use of software code to execute SQL queries, which is less complicated to handle and monitor efficiency, in addition to safer.
Utilizing Rockset’s Question Lambdas and APIs additionally shrank the quantity of information we would have liked to course of. This accelerates the pace at which we will ship solutions to clients looking our web site, and to retailer staff and company employees internally looking our stock administration system. Rockset additionally utterly eradicated database timeouts.
Rockset additionally provides us full confidence within the ongoing accuracy of our stock administration system with out having to always double-check towards every day stock counts. And it permits us to trace our provide chain in actual time and predict potential spikes in demand and shortages.
Rockset has been in manufacturing for us for greater than half a yr. Although we’re not but leveraging Rockset’s capabilities in complicated analytics or deep knowledge explorations, we’re greater than happy with the close to real-time, highly-accurate views of our stock we now have now – one thing that MySQL couldn’t ship.
Sooner or later we’re pondering of monitoring DMS to protect towards hiccups or replication errors, although there have been none so far. We’re additionally contemplating utilizing Rockset’s APIs to create objects as we ingest stock transactions.
Rockset has had a large impact on our enterprise. Its pace and accuracy give us unprecedented visibility into our stock and provide chain, which is mission vital for us.
Rockset helped us thrive throughout Black Friday and Christmas 2021. For the primary time, I used to be in a position to get some sleep through the vacation season!
