Looking for the proper campsite is usually a hit-and-miss affair, as one seeks the proper mixture of a view, enough parking, and proximity to neighbors and companies, amongst different elements. When it got here to deciding on a instrument to handle its huge knowledge pipeline, the net reservation firm Campspot didn’t need to look any additional than Apache Airflow and, finally, the hosted Airflow service from Astronomer.
In the event you’ve obtained a hankering for some tenting, then Campspot is an efficient place to start out. Based in 2015 in Grand Rapids, Michigan, the software-as-a-service (SaaS) firm lets clients make reservations at greater than 2,700 non-public campgrounds, RV resorts, cabins, and “glamping” areas in the USA and Canada. All instructed, Campspot manages the reservations for greater than 230,000 campsites throughout North America, which has helped earn the corporate the nickname “the Expedia of campgrounds.”
Whereas campers would possibly measure their total satisfaction by the variety of s’mores consumed per day, Campspot’s companions–the campground homeowners–want only a bit extra knowledge. For example, each day, they should know which of their campsites are reserved, what number of whole are reserved, and the way that compares to earlier time intervals.
The duty of conserving the campground homeowners’ knowledge urge for food correctly sated falls to John Marriott, supervisor of Campspot’s knowledge platform workforce. In line with Marriott, the corporate runs a nightly batch job that takes the newest knowledge from the homegrown reservation administration system and rolls it up into its knowledge warehouse. This knowledge is then bundled up into PDF of CSV studies which are both emailed to Campspot companions or made accessible for viewing on a Net-based dashboard. The corporate additionally affords a “indicators” product to its companions that compares their present reservations to an anonymized set of opponents of their house.
Previous to 2022, managing all of those knowledge transformation jobs was largely a handbook affair. It was as much as particular person engineers to determine how knowledge a knowledge pipeline must be constructed to allow knowledge to circulation from the reservation system, which runs on a mixture of Postgres, MySQL, and DynamoDB databases, into its knowledge warehouse, which runs on a mix of Snowflake and Postgres.
“The corporate was simply type of setting programmers on these issues, and so they had been simply writing issues in any which means,” Marriott says. “So we had numerous jobs that had been both type of bolted onto the facet of our software or simply lived in quite a lot of locations and had been orchestrated in several methods.”
Getting the nightly batch job finished started to be an issue. Whereas it ought to have taken about 5 minutes, it could generally take two or three hours to finish. With campgrounds unfold throughout seven completely different time zones, Campspot was beneath the gun to ship the data vital to campground homeowners.
“After the third or fourth time that you just bump up the timeout on this batch job from one hour to 2 hours to 3 hours or one thing, it’s like, all proper, this isn’t the appropriate answer simply to maintain letting this factor run,” he tells BigDATAwire. “If it’s taking two hours, that’s only a crimson flag. Like, there’s obtained to be a greater means to do that.”
When issues arose, troubleshooting points on this decentralized, ad-hoc atmosphere hinged on but extra decentralized, ad-hoc work.
“When one thing fails, first it’s good to work out what’s the precise infrastructure for this job, after which go take into consideration easy methods to repair it,” Marriott says. “And so that you’re all the time type of juggling these issues.”
Marriott and his workforce realized they wanted to get a deal with on these knowledge pipeline jobs. That they had heard of instruments that may automate the execution of 1000’s of information pipelines. They perceived that Apache Airflow was the early chief on this house, and after investigating Airflow, they adopted it in 2022.
“We noticed Airflow as our answer of ‘Let’s get every thing beneath one roof,’ as an alternative of simply having issues type of blended round,” Marriott says.
Mariott’s engineers instantly took to Airflow. Whereas Airflow affords a number of other ways to work with the product, together with GUIs, Campspot’s builders are code-first sorts, and so they gravitated to Airflow’s command line and programmatic interfaces. Equally, in addition they favored how Airflow and its Python-based batch jobs simply match into their present DevOps workflows.
“We’re used to utilizing GitHub and having every thing be code, as opposed [to going through a GUI,]” Mariott says. “I imply, these instruments are nice, however as soon as you understand how to put in writing code, you type of really feel like your fingers are tied a bit bit [using a GUI]. Nearly all of our work is completed in code. So it’s a pull request, it goes by our approval course of, and Airflow simply suits in actually naturally with the remainder of the software program engineering that we’re doing.”
Campspot engineers discovered it simple to outline their knowledge transformation jobs in Airflow utilizing Python, Airflow’s native language; Mariott estimates that 95% of Airflow jobs are in Python. The software program additionally permits Campspot to arrange completely different knowledge pipelines to course of campground homeowners’ knowledge relying on the timezone they’re in, additional rushing up the nightly batch run.
As an AWS store, Campspot determined to benefit from AWS’s Amazon Managed Workflows for Apache Airflow (MWAA) providing out of the gate. Whereas AWS’s managed Airflow atmosphere was higher than what that they had in place earlier than, Campspot discovered that MWAA wasn’t as simple to handle as that they had initially hoped.
“Establishing the deployment pipeline was not as easy,” Marriott recollects. “Having a number of environments was pricey. If we wished a separate dev and staging and manufacturing environments, these had been only a straight a number of of the fee.”
The corporate regarded to a different hosted Airflow atmosphere from Astronomer, the corporate behind the open supply Airflow mission. Astronomer’s Astro atmosphere additionally runs on AWS, however doesn’t double (or triple) your value for working improvement and testing environments along with manufacturing, Marriott says. Shifting Campspot to additionally lowered the operational burden on Campspot engineers, Mariott says.
“We’d moderately pay the platform price than pay that very same quantity in labor for us to be sustaining the platform,” he says. “They deal with every thing, aside from the half that we’ve to be doing. We have to write the roles which are particular to our use circumstances, and we don’t need to do something greater than that.”
Nonetheless, transferring to Astronomer didn’t completely streamline the administration of Airflow, a minimum of not initially. Since Campspot was working Astro in its personal VPC, it was nonetheless uncovered to further complexity.

When troubles arose with an Airflow job, Campspot engineers wanted to analyze a number of programs, together with the AWS batch job that was used to kick off the Airflow job, the Amazon CloudWatch job that screens it, and the Amazon EventBridge job that scheduled it.
“When one thing fails, you’re going and searching in all these locations and getting the logs after which these batch jobs are triggering, both hitting an endpoint within the code, one thing that was simply type of bolted on, possibly a Lambda or who is aware of what,” Marriott says. “And it’s only a lot to juggle, quite a bit to maintain in your head.”
So a few yr in the past, Campspot moved its Astro deployment from its personal VPC into Astronomer’s atmosphere, additional decreasing the variety of completely different environments concerned and the floor space the place issues can go mistaken.
“All the scheduling and the working of it and the logging and investigating failures–it’s simply multi functional house,” Marriott says. “In order that’s the benefit for us.”
As People and Canadians set out in 2025 to seek out their favourite campgrounds, they most likely aren’t fascinated with how their stays are triggering knowledge transformation jobs flowing throughout the Web. However for the parents at Campspot who’re chargeable for conserving the information flowing, the existence of Airflow and Astronomer’s Astro service implies that they, too, are pleased campers.
