Commentary: When Fb solves technical issues, it defaults to open supply options like Presto.
Fb has been a little bit of a punching bag these days, and for good purpose. However for all its issues, Fb continues to be one of many preeminent open supply software program factories on Earth. From React to Apache Cassandra to PyTorch, Fb has open sourced a few of the world’s hottest software program, which, in flip, has given rise to firms constructed as much as commercialize these tasks.
Like Starburst, an organization began by Fb veterans to commercialize Presto, an open supply distributed SQL question engine for working interactive analytic queries towards knowledge sources of any dimension. Starburst simply raised $42 million to additional speed up Presto improvement and commercialization. In an interview with Starburst co-founder and CTO, Martin Traverso, he talked via how Fb’s engineering tradition gave life to Presto, and the open supply ethos that powers it.

A tradition of creation
Let’s rewind to 2012, when Fb’s infrastructure workforce was nonetheless knee-deep in Apache Hive, a knowledge warehouse undertaking the corporate had created and open sourced again in 2010. Fb had an enormous 300 petabyte Hive knowledge warehouse, which sounds nice, and it was. However it was additionally extremely sluggish. As Traverso associated, a Fb knowledge scientist as soon as quipped, “It is a good day once I can run six Hive queries.” Hive, for all its deserves, was a giant productiveness loss.
There was speak all through the Fb knowledge infrastructure workforce about constructing one thing higher, however it was Traverso, together with Dain Sundstrom, David Phillips, and Eric Hwang, who acquired the nod to go construct one thing higher. Phillips, particularly, had used knowledge warehouse engines and had each the motivation and the eagerness to do one thing about Hive, Traverso mentioned.
If the foursome had waited, maybe they might have used Apache Drill (the primary design assembly was in late 2012). However that is not how Fb engineering works. There have been no apparent alternate options, they usually had a necessity. “We needed to do it by ourselves,” he mentioned. And they also did: In 2012, they launched Presto.
A tradition of open supply
This does not clarify why they open sourced it. It helped that Sundstrom had been concerned in Apache Geronimo, however even that does not actually adequately cowl the rationale for opening it up. As Traverso associated, the founders weren’t merely hoping to unravel an instantaneous Fb need–they wished to construct one thing that may endure and be broadly relevant:
We like open supply. We consider in open supply. We consider that the perfect software program is written by passionate builders working in open supply communities. We wished to construct one thing that may be usable for Fb, but in addition one thing that could possibly be utilized by everybody else on the planet. Additionally, by making it out there to different folks, we are able to make it higher as a result of we are able to get different folks concerned that produce other wants and thereby construct one thing that’s extra broadly relevant than only a single firm and single use case.
And they also have. At present there’s a diverse and growing body of contributors, sparked early on by appreciable involvement from Teradata, in addition to Netflix, LinkedIn, and others. Teradata had roughly 20 folks engaged on Presto at one level, with maybe half of these engaged on the Presto core. Over time a few of these, together with Justin Borgman, who ran Teradata’s Apache Hadoop-related merchandise, finally left to work on Presto full-time below the auspices of Starburst, which was based in 2017.

In line with Traverso, the Presto workforce has labored onerous to make it simple to contribute to the undertaking. From a technical standpoint, Traverso mentioned, they’ve tried to make the code accessible and straightforward to know. “It is pretty uniform in order to make it simple to see what is going on on within the code. There are some tasks the place you bounce in and it is a huge spaghetti plate, and it is form of onerous to comply with all of the threads and make sense of it.” Presto, in contrast, is extra structured across the sights within the code, making it simpler for somebody to judge how and the place they will make a significant contribution.
As well as, the Presto founders perceive that customers will probably surrender if they can not do one thing helpful with the undertaking inside the first 5 minutes. Presto makes it easy to go from obtain to working the question engine in minutes.
Lastly, there’s the group. The Presto Slack channel is presently 2,200 sturdy, with as many as 500 energetic at any given time. “It is one of the crucial energetic open supply tasks I’ve seen,” famous Traverso. These persons are glad to assist new customers get began with the undertaking, or work with would-be contributors to facilitate their contributions.
Although Presto was initially used to question knowledge in HDFS (Hadoop), Traverso and the opposite founders wanted it to have the ability to question not solely Fb’s personalized HDFS, but in addition the “off-the-shelf” open supply HDFS. In order that they created an abstraction over the storage layer, then made it pluggable. As a result of there is a very clear interface between the engine and the storage layer, it has allowed the Presto group to construct connectors for a big selection of information sources, together with Cassandra, MongoDB, Elasticsearch, and over 30 extra.
“The extra folks become involved, the higher the software program will get,” mentioned Traverso.
It is value remembering that Fb has made it the default for engineers like Traverso to construct and open supply software program exactly to assemble communities round these tasks. They could be born at Fb, however due to Fb’s embrace of open supply, they do not die there.
