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 firms for his or her prospects in Brazil and the US.
We’ve come a good distance since 2011 after I joined Dimona to launch our first web site. At the moment, our API permits our B2B prospects to add {custom} designs, and mechanically 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. At the moment, we’ve got greater than 80,000 B2B prospects equipped by our factories in Rio de Janeiro and South Florida. We are able to dropship on behalf of our B2B prospects wherever in Brazil and the U.S. and assist them keep away from the trouble and value of import taxes.
Our enterprise is flourishing. Nevertheless, we nearly didn’t get right here because of rising pains with our knowledge expertise.
Off-the-Shelf ERP Methods Too Restricted
As a consequence of 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 means of the reducing, 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 prospects.
Not solely is our provide chain longer than regular, so is the scale and variety of our stock. We’ve got 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 objects can also be larger 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 may solely retailer the end-of-day stock counts by location, quite than a full document of every particular person merchandise because it traveled by means of our provide chain.
Monitoring solely stock counts minimized the quantity of knowledge we needed to retailer. Nevertheless, 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 onerous 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 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 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 knowledge we have been accumulating in actual time. Out of the blue, 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 developments.
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 aspect. 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 advantageous for a short time earlier than turning into sluggish and unresponsive once more.
Pandemic-Led Enlargement
Compounding the difficulty was the COVID-19’s arrival in early 2020. Out of the blue we had many worldwide prospects 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 have been by means 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. Another choice was to proceed recording all stock actions however use them solely to double-check our separately-tracked stock counts, quite 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 might drive us to take care of two separate datasets – datasets that must be consistently in contrast in opposition to one another with no assure that it might enhance accuracy.
We would have liked a greater expertise resolution, one that would retailer huge 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-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 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 various.
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 repeatedly replicate knowledge from Aurora into Rockset, which does the entire knowledge processing, aggregations and calculations.
“The place Rockset actually shines is its potential to ship exact, correct views of our stock in near-real time.”

This connection was extraordinarily straightforward to arrange because of Rockset’s integration with MySQL. And it’s quick: DMS replicates updates from a million+ Aurora paperwork to Rockset each minute, turning into accessible to customers immediately.
The place Rockset actually shines is its potential 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 utility code to execute SQL queries, which is simpler to handle and monitor 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 prospects searching our web site, and to retailer workers 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 consistently double-check in opposition to day by 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 12 months. Although we aren’t 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’ve got now – one thing that MySQL couldn’t ship.
Sooner or later we’re considering of monitoring DMS to protect in opposition to hiccups or replication errors, although there have been none to this point. We’re additionally contemplating utilizing Rockset’s APIs to create objects as we ingest stock transactions.
Rockset has had an enormous impact on our enterprise. Its velocity 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 in the course of the vacation season!
