In Punchh, we have chosen AWS’s Document DB technology to combat 2X traffic while reducing our production DB spending by 20%.

Bhanu Mohanty, our Chief Architect says, “AWS provided us with first-hand insight on the database services that were available to address the challenges we were facing. As an AWS Enterprise Support customer, we also had 24x7 technical support in finetuning the performance of our platform with Amazon DocumentDB.”

The full case study is below.

Introduction

Automation testing is the process of executing test cases using automation testing tools and frameworks, and generating automated test reports which compare actual results with expected results. There are various test automation tools such as Appium, Calabash, Selenium, Cypress etc. and by using these tools one can build a framework to suit one’s scenarios and requirements. Automation testing improves test coverage, enhances testing speed, early detection improves quality of testing and scores high on re-usability, simultaneity (on multiple devices and mobile applications) of the testing process.

At Punchh, we have 150+ loyalty based mobile…

THIS COVID-19 Impact Analysis Series designed by Punchh’s data team aims at sharing the real-time insight we have discovered when we study our consumer behavior data set.

In this sixth article of the series, we highlighted how some cuisine types are able to offset the steep drop in transactions by capturing higher value in each order (in other words, higher Average Order Value a.k.a AOV)

Due to the stay home directives, people commuting daily to the work has declined significantly. As a result, transaction volume and sales have declined by up to 50% within 6 weeks, however, AOV has increased…

THIS COVID-19 impact analysis series designed by Punchh’s data team aims at sharing the real-time insight we have discovered when we study our consumer behavior data set. In this fifth article, we analyzed how different food categories are being consumed, and provided a holistic view of the shift in consumer food habits. In addition, we show how different cuisine types are faring post the outbreak.

Over the past few weeks, there has been a significant shift in the way consumers are…

The job cluster is created ad-hoc when you run a job and the cluster is terminated when the job is complete. You cannot restart a job cluster. While the all-purpose cluster is great for development, testing, and coding collaboration, the one-time job cluster is significantly cheaper to run than an all-purpose cluster. Therefore the job cluster is especially suitable for production jobs.

Breakfast orders are in the decline

THIS COVID-19 impact Analysis Series designed by Punchh’s data team aims at sharing the real-time insight we have discovered when we study our consumer behavior data set. In our previous article, we provided our insight into the increase in the off-prem orders as % of total orders. In this fourth article, we have zoomed in on two categories within off-prem orders: delivery and takeout.

As of April 02, the governors of more than 40 states have imposed a stay-at-home directive, essentially putting 80% of Americans under lockdown. Under these circumstances, the off-prem orders as…
