The Linux Foundation last weekannounced that it will host Valkey , a forking of the Redis in - memory information stock . Valkey is backed byAmazonWeb Services , GoogleCloud , Oracle , Ericsson andSnap .
AWS and Google Cloud rarely back an undecided source fork together . Yet , when Redis Labs switched Redisaway from the permissive three - clause BSD licenseon March 20 and adopted the more restrictive Server Side Public License ( SSPL ) , a fork was always one of the most likely outcomes . At the time of the license variety , Redis Labs CEO Rowan Trollope said he “ would n’t be surprised if Amazon patronise a fork , ” as the new license requires commercial agreements to extend Redis - as - a - service , making it unsuited with the received definition of “ open source . ”
It ’s worth taking a few footmark back to look at how we got to this decimal point . Redis , after all , is among the most popular information stores and at the magnetic core of many large commercial and open source deployment .
A brief history of Redis
Throughout its lifetime , Redis has in reality see a few licensing disputes . Redis founder Salvatore Sanfilippo launch the labor in 2009 under the BSD license , part because he desire to be able to create a commercial ramification at some breaker point and also because “ the BSD [ license]allows for many branches to contend , with different licensing and development idea , ” he read in a recentHackerNewscomment .
After Redis quickly take in popularity , Garantia became the first major Redis service supplier . Garantia rebranded to RedisDB in 2013 , and Sanfilippo and the community pushed back . After some time , Garantia eventually changed its name to Redis Labs and then , in2021 , to Redis .
Sanfilippo link up Redis Labs in 2015 and later transferred his IP to Redis Labs / Redis , beforestepping downfrom the company in 2020 . That was only a duo of class after Redis change how it licence its Redis Modules , which include visualization peter , a node SDK and more . For those mental faculty , Redis first went with the Apache License with the addedCommons Clausethat restricts others from selling and hosting these modules . At the meter , Redis said that despite this change for the module , “ the license for exposed - rootage Redis was never changed . It is BSD and will always persist BSD . ” That dedication lasted until a few weeks ago .
Redis ’ Trollope reiterated in a statement what he tell me when he first announced these changes , underscore how the large cloud vender profited from the open origin version and are liberal to enter a commercial-grade agreement with Redis .

Cloud vendors backed Valkey
The current reality , however , is that the large cloud vender , with the notable exception ofMicrosoft , apace rallied behind Valkey . This branching originated at AWS , where longtime Redis upholder Madelyn Olson initially started the task in her own GitHub account . Olson told me that when the news broke , a lot of the current Redis maintainers speedily decided that it was meter to move on . “ When the news broke , everyone was just like , ‘ Well , we ’re not going to go impart to this new license , ’ and so as before long as I talked to everyone , ‘ Hey , I have this fork — we ’re trying to keep the old group together , ’ ” she say , “ jolly much everyone was like , ‘ yeah , I ’m now on board . ”
The original Redis private distribution channel include five maintainers : three from Redis , Olson and Alibaba’sZhao Zhao , as well as a small group of committers who also forthwith signed on to what is now Valkey . The upholder from Redis unsurprisingly did not sign on , but as David Nalley , AWS ’s director for open source scheme and selling , evidence me , the Valkey community would welcome them with open arms .
Olson noted that she always knew that this change was a possibility and well within the rights of the BSD licence . “ I ’m more just disappointed than anything else . [ Redis ] had been a serious steward in the past times , and I consider the residential area is kind of disappointed in the change . ”
Nalley take note that “ from an AWS perspective , it in all probability would not have been the pick that we wanted to see out of Redis Inc. ” But he also notice that Redis is well within its right to make this change . When inquire whether AWS had considered buying a license from Redis , he gave a diplomatic reply and noted that AWS “ considered a circle of thing ” and that nothing was off the mesa in the squad ’s determination qualification .
“ It ’s for sure their perquisite to make such a determination , ” he said . “ While we have , as a result , made some other decisions about where we ’re going to center our vitality and our time , Redis remains an important partner and client , and we apportion a big number of customer between us . And so we hope they are successful . But from an subject source linear perspective , we ’re now invested in guarantee the success of Valkey . ”
It ’s not often that a ramification derive together this quickly and is capable to forgather the support of this many company under the auspice of the Linux Foundation ( LF ) . That ’s something that previous Redis forks like KeyDB did n’t have going for them . But as it turns out , some of this was also uncaused timing . Redis ’s declaration come decently in the middle of the European interpretation of the Cloud Native Computing Foundation ’s KubeCon league , which was hold in Paris this class . There , Nalley meet up with the LF ’s executive director , Jim Zemlin .
“ It ruined KubeCon for me , because all of a sudden , I ended up in a lot of conversation about how we respond , ” he said . “ [ Zemlin ] had some concerns and volunteer the Linux Foundation as a potential home . So we belong through the physical process of introducing Madelyn [ Olson ] and the rest of the maintainers to the Linux Foundation , just to see if they thought that it was move to be a compatible move . ”
What’s next?
The Valkey team is working on flummox a compatibility release out that supply current Redis users with a conversion path . The community is also working on an improved shared clustering system , improved multi - threaded operation and more .
With all of this , it ’s not likely that Redis and Valkey will stay aligned in their capabilities for long , and Valkey may not remain a drop - in Redis surrogate in the tenacious run . One surface area Redis ( the company ) is investing in is run beyond in - remembering to also using wink storage , with RAM as a declamatory , high - performance cache . That ’s whyRedis recently acquire Speedb . Olson noted that there are no concrete program for similar capability in Valkey yet , but did n’t prevail it out either .
“ There is a good deal of excitement flop now , ” Olson said . “ I think previously we ’ve been a petty technologically cautious and prove to make certain we do n’t break stuff . Whereas now , I think there ’s a lot of interest in building a tidy sum of new things . We still desire to make certain we do n’t break things but there ’s a lot more interest in updating engineering and attempt to make everything faster , more performant , more retentivity dense . [ … ] I intend that ’s sort of what happens when a changing of the guard happens because a clustering of previous maintainers are now fundamentally no longer there . ”
