When one of the co - creators of the popular undetermined informant stream - processing model Apache Flink set in motion a unexampled startup , it ’s deserving paying attention . Stephan Ewenwas among the founding squad of the opened rootage projection back in 2010 and then later became the CTO of Data Artisans , which drive to monetize Flink . Alibaba then acquired the company in 2019 and rebranded it as Ververica , with Ewen then spend the needful three age at the company before launching workflows - as - code startupRestate , together with Flink committers and former Data Artisan / Ververica co - workersIgal ShilmanandTill Rohrmann .
Restate , which says its overall missionary work is to make shell out lotion development easier , today announced that it has raised a $ 7 million seed funding around , hitting version 1.0 of its open BSL - licensed version and that it ’s launch its managed cloud religious service .
The promise of Restate is that it is so fast and lightweight that it will allow developers to employ it where traditional work flow systems would ’ve been too tedious and resource - intensive . That ’s backed by a durable execution railway locomotive that can set up fault - patient of communicating between services and process , and that integrate with single-valued function - as - a - service political platform like AWS Lambda and Cloudflare Workers . While idealistic for microservices architecture , developers can also use it for task waiting line , event processing or overhaul instrumentation in systems like inventory management or qualification .
It ’s worth noting that Restate is n’t the first to this concept , though . The open source platformTemporal , for example , volunteer a somewhat similar characteristic set , though the Restate team would likely argue that its system is faster and more lightweight .
Ewen say after 13 years with Flink , it was time to harness a new problem . “ While we were working on Flink , we had this set of use cases that keep fall up , where folks were kind of abusing Flink for transactional instrumentation - expressive style habit caseful , ” he assure me . “ And it was not great when they used it for that , but they told us they did n’t find anything else . ”
After come across users do this again and again , the team decide that if they were going to build another caller , they ’d look into how they could clear this problem more elegantly .
nearly every modern app today consists of chains of work flow that are handled by a lot Seth of services that have to dependably talk to each other . It takes a very experient team to establish a fault - tolerant distributed system like that — and many companies build up their own — but it ’s also table stake and not something that ’s inevitably going to help those company differentiate their product .

Looking at this , Ewen enjoin me , the team withdraw some of the stream - based processing ideas from Flink and then combine that with the workflows - as - code concept and a specialised event log — because at the core of every workflow railway locomotive is a log . “ Restate takes the workflow - as - code idea and lend a few other somewhat stream - processing - inspired ideas . We evolved it into a more oecumenical - design distributed programming model based on lasting execution , virtual objects and lasting hope — and put it on an event - drive foundation , ” Ewen said .
The engine that power that is very small and lightweight and , Ewen stress , fast — in part because it ships as a individual double star . He believes this will make the service usable in situations where you ’d not classically use a workflow engine — remember e - commerce shopping cart , for exemplar . A lightweight workflow engine , with its built - in warrant , long-lived instruction execution and retries if things go incorrect , assure that point in an abandoned shopping pushcart are released back to other customer after a set sentence , for example , derogate the risk of something fail in the process .
“ [ Restate ] does the classical work flow computer code thing , just on an extremely lightweight institution — and it goes a little further than just stock work flow use cases . It contain communicating and state management as a core concept , so you could really use it to also work up things that are not salutary case for workflow but still fit very well if you want to build a right microservice computer architecture , ” Ewen explained .
The ship’s company also today launch its hosted Restate Cloud into early access . For now , it ’s useable for free and Ewen was quite open about the fact that the team is still endeavor to image out how people will use it before deciding on how to monetize the service .
The company ’s financing unit of ammunition was led by Redpoint Ventures , with participation from Essence VC , firstminute capital and angels like Datadog founder Oli Pomel and Apache Kafka and Confluent founders Jay Kreps and Neha Narkhede . The company will expend the financing to hire and build out its substructure , as well as to bring its SDK to more languages ( it presently supports TypeScript , Java and Kotlin ) .
“ It ’s still challenging to make distributed transactional lotion right , resilient and scalable , ” said Kreps . “ Restate ’s approach of marry durable carrying out and event - driven architectures is a expectant footfall towards fixing that . ”
