The relative deserves of “open” have been hotly debated in our business for years. There is a feeling in some quarters that getting open up is effective by default, but this view does not usually totally look at the objectives getting served. What issues most to the huge majority of corporations are safety, efficiency, prices, simplicity, and innovation. Open really should usually be utilized in support of those people objectives, not as the purpose in by itself.
When we develop items at Snowflake, we examine in which open up benchmarks, open up formats, and open up resource can build the best final result for our shoppers. We imagine strongly in the favourable impact of open up and we are grateful for the open up resource community’s attempts, which have propelled the significant information revolution and much a lot more. But open up is not the reply in every occasion, and by sharing our wondering on this matter we hope to supply a handy perspective to others creating innovative technologies.

Open is often recognized to describe two broad elements: open up benchmarks and open up resource. We’ll appear at them every single in a lot more depth right here.
Open benchmarks encompass file formats, protocols, and programming designs, which contain languages and APIs. Even though open up benchmarks frequently supply value to people and sellers alike, it is vital to have an understanding of in which they serve increased-amount priorities and in which they do not.
We concur that open up file formats are an vital counter to the really genuine dilemma of vendor lock-in. Where by we vary is in the assertion that those people open up formats are the optimal way to signify information for the duration of processing, and that direct file entry really should be a key characteristic of a information system.
At 1st look, the means to specifically entry files in a conventional, very well-regarded structure is interesting, but it gets to be troublesome when the structure requirements to evolve. Contemplate an enhancement that allows greater compression or greater processing. How do we coordinate throughout all achievable people and purposes to have an understanding of the new structure?
Or look at a new safety capacity in which information entry is dependent on a broader context. How do we roll out a new privacy capacity that motives through a broader semantic knowledge of the information to keep away from re-identification of individuals? Is it needed to coordinate all achievable people and purposes to undertake these alterations in lockstep? What transpires if 1 of these is skipped?
Our very long experience with these trade-offs gives us a solid conviction about the excellent value of supplying abstraction and indirection vs . exposing raw files and file formats. We strongly imagine in API-driven entry to information, in increased-amount constructs abstracting absent actual physical storage aspects. This is not about rejecting open up it is about providing greater value for shoppers. We stability this with creating it really quick to get information in and out in conventional formats.
A great illustration of in which abstracting absent the aspects of file formats significantly will help finish people is compression. An means to transparently modify the underlying illustration of information to attain greater compression interprets to storage cost savings, compute cost savings, and greater efficiency. Exposing the aspects of file formats makes it following to impossible to roll out greater compression without the need of incurring very long migrations, breaking alterations, or extra complexity for purposes and builders.
Comparable troubles crop up when we consider about enhancements to safety, information governance, information integrity, privacy, and several other locations. The heritage of database programs delivers lots of illustrations, like iSAMS or CODASYL, displaying us that actual physical entry to information qualified prospects to an innovation dead finish. Much more lately, adopters of Hadoop observed them selves running high-priced, advanced, and unsecured environments that did not provide the promised efficiency.
In a entire world with direct file entry, introducing new abilities interprets into delays in realizing the advantages of those people abilities, complexity for application builders, and, potentially, governance breaches. This is yet another place arguing for abstracting absent the inner illustration of information to supply a lot more value to shoppers, whilst supporting ingestion and export of open up file formats.
Open protocols and APIs
Details entry procedures are a lot more vital than file formats. We all concur that steering clear of vendor lock-in is a key purchaser priority. But whilst some imagine that open up formats are the solution, the hefty lifting in any migration is actually about code and information entry, no matter if it is protocols and connectivity drivers, question languages, or company logic. All those who have long gone through a system migration can likely attest that the matter of file formats is a purple herring.
For us, this is in which open up issues most — it is in which high-priced lock-in can be avoided, information governance can be maximized, and better innovation is achievable. Concentrating on open up protocols and APIs is key to steering clear of complexity for people and enabling continuous, clear innovation.
The advantages cited for open up resource contain a better knowledge of the technologies, improved safety through transparency, lower prices, and group growth. Open resource can provide in opposition to some of these objectives, and does so mainly when technologies is installed on-premises, but the shift to managed products and services tremendously alters these dynamics.
When it arrives to better knowledge of code, look at that a sophisticated question processor is ordinarily crafted and optimized about a number of years by dozens of Ph.D. graduates. Building the resource code out there will not magically allow its people to have an understanding of its internal workings, but there may well be better value in surfacing information, metadata, and metrics that supply clarity to shoppers.
An additional component of this discussion is the want to copy and modify resource code. This can supply value and optionality to corporations that can commit to construct these abilities, but we’ve also viewed it direct to undesirable repercussions, which include fragmented platforms, significantly less agility to implement alterations, and competitive dysfunction.
This has usually been 1 of the main arguments for open up resource. When an organization deploys software package inside of its safety perimeter, resource code availability can without a doubt raise self-assurance about safety. But there is a rising consciousness of the hazards in software package supply chains, and advanced technologies alternatives often mixture many software package subsystems without the need of an knowledge of the comprehensive finish-to-finish impact on safety.
Thankfully there is a greater product, which is the deployment of technologies as managed cloud products and services. Encapsulation of the internal workings of these products and services will allow for a lot quicker evolution and fast delivery of innovation to shoppers. With added aim, managed products and services can eliminate the configuration stress and eradicate the hard work essential for provisioning and tuning.
Most corporations have regarded by now that not having to pay a software package license does not always signify lower prices. Apart from the value of upkeep and assistance, it ignores the value and complexity of deploying, updating, and split-fixing software package. Charge really should be measured in phrases of whole value and rate/efficiency out of the box. Right here, also, managed products and services are preferable, taking away among other things the will need to manage variations, function close to upkeep windows, and great-tune software package.
1 of the most potent areas of open up resource is the idea of group, by which a team of people function collaboratively to increase a technologies and support 1 yet another. But collaboration does not will need to suggest resource code contribution. We consider of group as people supporting 1 yet another, sharing best procedures, and speaking about future directions for the technologies.
As the shift from on-premises to the cloud and managed products and services continues, these matters of command, safety, value, and group recur. What is interesting is that the original objectives of open up resource are getting fulfilled in these cloud environments without the need of always supplying resource code for everyone—which is in which we commenced this discussion. We should not drop sight of the wanted outcomes by focusing on practices that may well no for a longer period be the best route to those people outcomes.
Open at Snowflake
At Snowflake, we consider about 1st rules, about wanted outcomes, about supposed and unintended repercussions, and, most importantly, about what’s best for our shoppers. As these kinds of, we don’t consider of open up as a blanket, non-negotiable attribute of our system, and we are really intentional in deciding upon in which and how we embrace it.
Our priorities are very clear:
- Provide the optimum concentrations of safety and governance
- Provide business-foremost efficiency and rate/efficiency through continuous innovation and
- Established the optimum concentrations of good quality, abilities, and simplicity of use so our shoppers can aim on deriving value from information without the need of the will need to manage infrastructure.
We also want to be certain that our shoppers keep on to use Snowflake due to the fact they want to and not due to the fact they’re locked in. To the extent that open up benchmarks, open up formats, and open up resource support us attain those people objectives, we embrace them. But when open up conflicts with those people objectives, our priorities dictate in opposition to it.
Open benchmarks at Snowflake
With those people priorities in intellect, we have totally embraced conventional file formats, conventional protocols, conventional languages, and conventional APIs. We’re intentional about in which and how we do so, and we have invested seriously in the means to leverage the abilities of our parallel processing engine so that shoppers can get their information out of Snowflake rapidly really should they will need or choose to. Even so, abstracting absent the aspects of our very low-amount information illustration will allow us to frequently increase our compression and provide other optimizations in a way that is clear to people.
We can also progress the controls for safety and information governance rapidly, without the need of the stress of running direct (and brittle) entry to files. Similarly, our transactional integrity advantages from our amount of abstraction and not exposing underlying files specifically to people.
We also embrace open up protocols, languages, and APIs. This features open up benchmarks for information entry, standard APIs these kinds of as ODBC and JDBC, and also Relaxation-dependent entry. Similarly, supporting the ANSI SQL conventional is key to question compatibility whilst supplying the energy of a declarative, increased-amount product. Other illustrations we embrace contain organization safety benchmarks these kinds of as SAML, OAuth, and SCIM, and many technologies certifications.
With good abstractions and promoting open up in which it issues, open up protocols allow us to move a lot quicker (due to the fact we don’t will need to reinvent them), allow our shoppers to re-use their knowledge, and empower rapidly innovation thanks to abstracting the “what” from the “how.”
Open resource at Snowflake
We provide a small quantity of factors that get deployed as software package alternatives into our customers’ programs, these kinds of as connectivity drivers like JDBC or Python connectors or our Kafka connector. For all of these we supply the resource code. Our purpose is to empower most safety for our shoppers, and we do so by providing our core system as a managed support, and we raise the peace of intellect for installable software package through open up resource.
Even so, a misguided application of open up can build high-priced complexity alternatively of very low-value simplicity of use. Offering stable, conventional APIs whilst not opening up our internals will allow us to rapidly iterate, innovate, and provide value to shoppers. But shoppers cannot create—deliberately or unintentionally—dependencies on inner implementation aspects, due to the fact we encapsulate them at the rear of APIs that stick to stable software package engineering procedures. That is a major reward for both equally sides, and it is key to keeping our weekly cadence of releases, to continuous innovation, and to resource performance. Clients who have migrated to Snowflake tell us continually that they enjoy those people choices.
The interface to our totally managed support, run in its very own safety perimeter, is the contract amongst us and our shoppers. We can do this due to the fact we have an understanding of every element and commit a fantastic amount of money of assets to safety. Snowflake has been evaluated by safety teams throughout the gamut of enterprise profiles and industries, which include really controlled industries these kinds of as healthcare and money products and services. The system is not only safe, but the separation of the safety perimeter through the clean up abstraction of a managed support simplifies the career of securing information and information programs for shoppers.
On a closing note, we enjoy our user groups, our purchaser councils, and our user conferences. We totally embrace the value of a vibrant group, open up communications, open up message boards, and open up conversations. Open resource is an orthogonal principle, from which we do not shy absent. For illustration, we collaborated on open up sourcing FoundationDB, and manufactured considerable contributions to evolving FoundationDB further.
Even so, we don’t extrapolate from this to say there is an inherent advantage to open up resource software package. We could equally have used a distinctive operational store and a distinctive product of creating it to accommodate our requirements if wanted. The FoundationDB illustration illustrates our key thesis: Open is a fantastic assortment of initiatives and processes, but it is 1 of several resources. It is not the hammer for all nails and is the best preference only in some cases.
