Properly, that was fast. Barely a 12 months after Kafka-compatible streaming startup WarpStream Labs opened its digital doorways, it’s been acquired by Confluent, the business outfit behind Apache Kafka. The massive get for Confluent is WarpStream’s S3-based information streaming providing, which WarpStream claims eliminates the costly inter-networking charges that plagues Kafka within the cloud. Confluent additionally takes out a possible competitor.
WarpStream Labs was based in July 2023 by two Datadog engineers, Richard Artoul and Ryan Worl, with the purpose of delivering a quick cloud-native information streaming platform that was totally appropriate with Apache Kafka, which continues to dominate the streaming information panorama. Artoul, who’s the CEO, described the Chicago-based firm’s distinctive streaming structure in his introductory weblog publish, appropriately titled “Kafka is lifeless, lengthy stay Kafka.”
“WarpStream is an Apache Kafka protocol appropriate information streaming platform constructed straight on prime of S3,” Artoul writes. “It’s delivered as a single, stateless Go binary so there aren’t any native disks to handle, no brokers to rebalance, and no ZooKeeper to function. WarpStream is 5-10x cheaper than Kafka within the cloud as a result of information streams on to and from S3 as a substitute of utilizing inter-zone networking, which may be over 80% of the infrastructure price of a Kafka deployment at scale.”

The motion of Kafka information inside an Availability Zone is an actual drawback for the Kafka structure, Artoul says, and in the end contributes to information storage prices which can be about 10-20x extra per GiB than S3 storage.
“Kafka was designed to run in LinkedIn’s information facilities, the place the community engineers didn’t cost their software builders for transferring information round,” Artoul wrote in his introductory weblog. “However at present, most Kafka customers are working it on a public cloud, an atmosphere with fully completely different constraints and value fashions. Sadly, until your group can decide to 10s or 100s of hundreds of thousands of {dollars} per 12 months in cloud spend, there isn’t any escaping the physics of this drawback.”
As a substitute of constructing customized instruments to assist automate the administration of Kafka information, Artoul and Worl determined to take a radically simiplified strategy. They have been knowledgeable by their work at DataDog, the place they constructed a columnar database for observability information working straight on S3. “Once we have been executed, we had a (largely) stateless and auto scaling information lake that was extraordinarily price efficient, by no means ran out of disk house, and was trivial to function,” he write. “Virtually in a single day our Kafka clusters all of the sudden appeared historical by comparability.”

By growing WarpStream round S3, Artoul and Worl felt they have been following within the footsteps of Databricks and Snowflake, which “lean into cloud economics by designing their methods from teh floor up round commity object storage.”
WarpStream Labs was rising its BYOC providing and had a full complement of options it was wanting so as to add. It has raised $20 million in enterprise capital, and had greater than a dozen staff, along with firms like Grafana Labs, Zomato, PostHog, and others. Then Jay Kreps, the CEO and co-founder of Confluent and one of many co-creators of Kafka, got here calling on the 2 founders.
Kreps preferred the BYOC strategy that WarpStream had taken, notably because it pertains to enabling clients to take care of management of their information whereas additionally delivering a totally managed expertise in in clients’ personal cloud accounts. That was one thing that Confluent had been engaged on, too.
“Once we checked out merchandise that labored this manner they have been typically the worst of each worlds: self-managed information methods that had been forklifted into the cloud with semi-managed fashions that left duty for safety and uptime fairly imprecise,” Kreps wrote in a weblog publish yesterday.
It was WarpStream’s “distinctive architectural strategy” that caught Kreps’ consideration, and what in the end led to a gathering in New York a couple of months again. That assembly finally culminated in a deal getting executed, and yesterday’s acquisition announcement, the phrases of which weren’t disclosed.

Confluent’s plan requires the WarpStream product to proceed to be developed and supported. It should sit smack dab in the course of the Confluent lineup, proper between Confluent Platform, which delivers a lot of management however is tough to handle, and Confluent Cloud, which is simple to handle however doesn’t supply a whole lot of management.
“I’ve been deeply impressed with WarpStream–it’s BYOC executed proper,” Kreps says in a press launch. “With this acquisition, we now have a knowledge streaming providing for everybody.”
Particularly, Confluent sees WarpStream being adopted by organizations working “giant scale workloads with relaxed latency necessities in their very own cloud atmosphere.” That would come with issues like processing enormous observability streams and loading information lakes.
“At present the WarpStream product remains to be a younger startup product, so it gained’t instantly be a match for all clients,” Kreps says within the weblog, “however we plan to put money into safety and hardening over time to convey it as much as the identical enterprise-grade requirements as Confluent Platform and Confluent Cloud, in addition to combine it into our methods for ease of signup, billing, and account administration.
There may even be some sharing of parts between WarpStream and the Confluent-developed merchandise, together with issues like information connectors, stream processing, and governance options, Kreps says.

In the meantime, the WarpStream crew has a full listing of options they’re engaged on, together with assist for Kafka transactions, cluster quotas, a BYOC schema registry, a mirroring product known as Orbit, active-active multi-region clusters, and buyer management planes for Google Cloud and Azure (it at present solely helps AWS).
“Many bulletins like this proceed to lament that the product is shutting down or radically altering, however we’re doing fairly the other,” Artoul wrote in his weblog publish at present, appropriately titled “WarpStream Is Useless, Lengthy Reside WarpStream.” WarpStream is about to get higher–quite a bit higher–with the sources and backing of the chief in streaming.”
