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. Immediately, our API permits our B2B clients to add {custom} designs, and routinely 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 delivery had been main improvements for the Latin American attire business, and it enabled us to develop in a short time. Immediately, now we have greater than 80,000 B2B clients equipped by our factories in Rio de Janeiro and South Florida. We will dropship on behalf of our B2B clients wherever in Brazil and the U.S. and assist them keep away from the trouble and value of import taxes.

Our enterprise is prospering. Nonetheless, we nearly didn’t get right here on account of rising pains with our information expertise.



Off-the-Shelf ERP Techniques Too Restricted

On account of our vertically-integrated enterprise mannequin, our provide chain is longer than most clothes makers. We have to observe 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 now have as much as a million t-shirts in inventory relying on the season. And because of the many {custom} designs, colours, materials and sizes that we provide, the variety of distinctive objects can also be increased than different attire makers.

We tried many off-the-shelf ERP programs to handle our stock end-to-end however nothing proved as much as the duty. Specifically, limitations in these programs 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 knowledge we needed to retailer. Nonetheless, it additionally meant that once we tried to match these counts with the stock actions we did have on file, mysterious errors emerged that we couldn’t reconcile. That made it exhausting for us to belief our personal stock information.

MySQL Crumbles Beneath Analytic Load

In 2019, we deployed our personal custom-built stock administration system to our predominant 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. Moderately than simply document end-of-day stock totals, we recorded each stock motion utilizing three items of knowledge: 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 fingers 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 knowledge we had been accumulating in actual time. Out of the blue, we had been importing 300,000 transactions to Aurora each two weeks. Nevertheless it additionally enabled us to question our information to find the precise location of a specific t-shirt at any given time, in addition to view high-level stock totals and traits.

At first, Aurora was capable of deal with the duty of each storing and aggregating the info. 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 wonderful for a short time earlier than turning into sluggish and unresponsive once more.

Pandemic-Led Growth

Compounding the difficulty was the COVID-19’s arrival in early 2020. Out of the blue we had many worldwide clients clamoring for a similar drop cargo providers we supplied 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 right down to the purpose of being unusable. And our payments from doing even easy aggregations in Aurora had been by way of the roof.

We had 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 may keep away from overtaxing the Aurora database’s meager analytical capabilities. However it might power us to take care of two separate datasets – datasets that must be always in contrast towards one another with no assure that it might enhance accuracy.

We would have liked a greater expertise answer, one that might retailer huge information units and question them in quick, automated methods in addition to make fast, easy information aggregations. And we would have liked it quickly.

Discovering Our Answer

I checked out a number of disparate choices. I thought-about a blockchain-based system for our ledger earlier than rapidly dismissing it. Inside AWS, I checked out DynamoDB in addition to one other ledger database provided by Amazon. We couldn’t get DynamoDB to ingest our information, 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 exchange query-challenged Aurora with a sooner 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 information from Aurora into Rockset, which does all the information 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, turning into out there 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 simpler to handle and observe efficiency, in addition to safer.

Utilizing Rockset’s Question Lambdas and APIs additionally shrank the quantity of knowledge we would have liked to course of. This accelerates the velocity at which we are able to ship solutions to clients shopping our web site, and to retailer staff and company employees internally looking out our stock administration system. Rockset additionally fully 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 information explorations, we’re greater than glad with the close to real-time, highly-accurate views of our stock now we have now – one thing that MySQL couldn’t ship.

Sooner or later we’re considering of monitoring DMS to protect towards hiccups or replication errors, although there have been none thus 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 velocity and accuracy give us unprecedented visibility into our stock and provide chain, which is mission essential for us.

Rockset helped us thrive throughout Black Friday and Christmas 2021. For the primary time, I used to be capable of get some sleep through the vacation season!
