The relative deserves of “open” have been hotly debated in our marketplace for decades. There is a perception in some quarters that becoming open up is beneficial by default, but this check out does not usually thoroughly take into account the objectives becoming served. What issues most to the broad bulk of businesses are stability, general performance, expenditures, simplicity, and innovation. Open should really usually be utilized in support of those objectives, not as the intention in alone.
When we create goods at Snowflake, we appraise in which open up requirements, open up formats, and open up source can create the finest outcome for our prospects. We imagine strongly in the optimistic effect of open up and we are grateful for the open up source community’s initiatives, which have propelled the big knowledge revolution and much far more. But open up is not the respond to in each individual instance, and by sharing our wondering on this subject we hope to present a valuable perspective to others making modern technologies.

Open is typically understood to describe two wide components: open up requirements and open up source. We’ll glimpse at them every single in far more detail below.
Open requirements encompass file formats, protocols, and programming designs, which involve languages and APIs. Despite the fact that open up requirements frequently present worth to users and distributors alike, it’s significant to understand in which they provide greater-amount priorities and in which they do not.
We concur that open up file formats are an significant counter to the really authentic problem of seller lock-in. Wherever we vary is in the assertion that those open up formats are the exceptional way to characterize knowledge during processing, and that immediate file accessibility should really be a vital characteristic of a knowledge system.
At very first look, the means to directly accessibility information in a regular, effectively-known format is interesting, but it gets to be troublesome when the format demands to evolve. Take into account an improvement that enables better compression or better processing. How do we coordinate across all feasible users and applications to understand the new format?
Or take into account a new stability capacity in which knowledge accessibility is dependent on a broader context. How do we roll out a new privacy capacity that factors by means of a broader semantic comprehension of the knowledge to prevent re-identification of persons? Is it required to coordinate all feasible users and applications to undertake these modifications in lockstep? What happens if a single of these is missed?
Our prolonged practical experience with these trade-offs presents us a solid conviction about the superior worth of supplying abstraction and indirection compared to exposing uncooked information and file formats. We strongly imagine in API-pushed accessibility to knowledge, in greater-amount constructs abstracting absent physical storage information. This is not about rejecting open up it’s about delivering better worth for prospects. We equilibrium this with generating it really easy to get knowledge in and out in regular formats.
A fantastic illustration of in which abstracting absent the information of file formats drastically allows finish users is compression. An means to transparently modify the underlying illustration of knowledge to realize better compression interprets to storage price savings, compute price savings, and better general performance. Exposing the information of file formats tends to make it next to not possible to roll out better compression without having incurring prolonged migrations, breaking modifications, or extra complexity for applications and builders.
Equivalent issues occur when we imagine about enhancements to stability, knowledge governance, knowledge integrity, privacy, and several other locations. The record of database systems features plenty of examples, like iSAMS or CODASYL, demonstrating us that physical accessibility to knowledge qualified prospects to an innovation useless finish. Additional not long ago, adopters of Hadoop identified by themselves taking care of highly-priced, elaborate, and unsecured environments that did not produce the promised general performance.
In a earth with immediate file accessibility, introducing new abilities interprets into delays in recognizing the positive aspects of those abilities, complexity for software builders, and, potentially, governance breaches. This is another level arguing for abstracting absent the internal illustration of knowledge to present far more worth to prospects, though supporting ingestion and export of open up file formats.
Open protocols and APIs
Details accessibility methods are far more significant than file formats. We all concur that averting seller lock-in is a vital customer precedence. But though some imagine that open up formats are the alternative, the significant lifting in any migration is seriously about code and knowledge accessibility, whether it’s protocols and connectivity drivers, query languages, or business enterprise logic. Those people who have gone by means of a procedure migration can possible attest that the subject of file formats is a purple herring.
For us, this is in which open up issues most — it’s in which highly-priced lock-in can be avoided, knowledge governance can be maximized, and larger innovation is feasible. Concentrating on open up protocols and APIs is vital to averting complexity for users and enabling constant, transparent innovation.
The positive aspects cited for open up source involve a larger comprehension of the technologies, enhanced stability by means of transparency, lessen expenditures, and group growth. Open source can produce versus some of these objectives, and does so principally when technologies is set up on-premises, but the shift to managed services enormously alters these dynamics.
When it comes to larger comprehension of code, take into account that a innovative query processor is usually crafted and optimized over various decades by dozens of Ph.D. graduates. Generating the source code offered will not magically enable its users to understand its inner workings, but there may perhaps be larger worth in surfacing knowledge, metadata, and metrics that present clarity to prospects.
Another facet of this dialogue is the desire to duplicate and modify source code. This can present worth and optionality to businesses that can spend to build these abilities, but we have also seen it lead to unwanted penalties, which include fragmented platforms, significantly less agility to employ modifications, and competitive dysfunction.
This has usually been a single of the major arguments for open up source. When an firm deploys program in just its stability perimeter, source code availability can indeed boost confidence about stability. But there is a escalating consciousness of the hazards in program offer chains, and elaborate technologies alternatives typically combination many program subsystems without having an comprehension of the whole finish-to-finish effect on stability.
Luckily for us there is a better product, which is the deployment of technologies as managed cloud services. Encapsulation of the inner workings of these services makes it possible for for speedier evolution and speedy supply of innovation to prospects. With supplemental aim, managed services can clear away the configuration stress and remove the effort essential for provisioning and tuning.
Most businesses have acknowledged by now that not spending a program license does not always necessarily mean lessen expenditures. Aside from the expense of maintenance and assistance, it ignores the expense and complexity of deploying, updating, and crack-correcting program. Expense should really be measured in terms of total expense and selling price/general performance out of the box. Listed here, too, managed services are preferable, taking away amongst other matters the will need to manage variations, perform all over maintenance home windows, and fine-tune program.
A single of the most strong aspects of open up source is the idea of group, by which a team of users perform collaboratively to enhance a technologies and support a single another. But collaboration does not will need to suggest source code contribution. We imagine of group as users helping a single another, sharing finest procedures, and talking about long term instructions for the technologies.
As the shift from on-premises to the cloud and managed services proceeds, these topics of manage, stability, expense, and group recur. What is attention-grabbing is that the authentic objectives of open up source are becoming achieved in these cloud environments without having always supplying source code for everyone—which is in which we began this dialogue. We have to not drop sight of the desired results by concentrating on tactics that may perhaps no lengthier be the finest route to those results.
Open at Snowflake
At Snowflake, we imagine about very first principles, about desired results, about meant and unintended penalties, and, most importantly, about what’s finest for our prospects. As these types of, we don’t imagine of open up as a blanket, non-negotiable attribute of our system, and we are really intentional in selecting in which and how we embrace it.
Our priorities are obvious:
- Provide the highest ranges of stability and governance
- Deliver marketplace-top general performance and selling price/general performance by means of constant innovation and
- Established the highest ranges of high-quality, abilities, and ease of use so our prospects can aim on deriving worth from knowledge without having the will need to manage infrastructure.
We also want to be certain that our prospects 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 requirements, open up formats, and open up source support us realize those objectives, we embrace them. But when open up conflicts with those objectives, our priorities dictate versus it.
Open requirements at Snowflake
With those priorities in brain, we have thoroughly embraced regular file formats, regular protocols, regular languages, and regular 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 motor so that prospects can get their knowledge out of Snowflake rapidly should really they will need or decide on to. However, abstracting absent the information of our very low-amount knowledge illustration makes it possible for us to frequently enhance our compression and produce other optimizations in a way that is transparent to users.
We can also progress the controls for stability and knowledge governance rapidly, without having the stress of taking care of immediate (and brittle) accessibility to information. Likewise, our transactional integrity positive aspects from our amount of abstraction and not exposing underlying information directly to users.
We also embrace open up protocols, languages, and APIs. This features open up requirements for knowledge accessibility, regular APIs these types of as ODBC and JDBC, and also Rest-based accessibility. Likewise, supporting the ANSI SQL regular is vital to query compatibility though offering the energy of a declarative, greater-amount product. Other examples we embrace involve business stability requirements these types of as SAML, OAuth, and SCIM, and a lot of technologies certifications.
With appropriate abstractions and promoting open up in which it issues, open up protocols enable us to transfer speedier (due to the fact we don’t will need to reinvent them), enable our prospects to re-use their know-how, and help quick innovation due to abstracting the “what” from the “how.”
Open source at Snowflake
We produce a tiny range of elements that get deployed as program alternatives into our customers’ systems, these types of as connectivity drivers like JDBC or Python connectors or our Kafka connector. For all of these we present the source code. Our intention is to help most stability for our prospects, and we do so by delivering our core system as a managed support, and we boost the peace of brain for installable program by means of open up source.
However, a misguided software of open up can create highly-priced complexity instead of very low-expense ease of use. Giving stable, regular APIs though not opening up our internals makes it possible for us to rapidly iterate, innovate, and produce worth to prospects. But prospects can not create—deliberately or unintentionally—dependencies on internal implementation information, due to the fact we encapsulate them guiding APIs that comply with reliable program engineering procedures. That is a main benefit for the two sides, and it’s vital to maintaining our weekly cadence of releases, to constant innovation, and to resource efficiency. Prospects who have migrated to Snowflake tell us regularly that they recognize those options.
The interface to our thoroughly managed support, run in its very own stability perimeter, is the deal among us and our prospects. We can do this due to the fact we understand each individual element and commit a great amount of money of methods to stability. Snowflake has been evaluated by stability teams across the gamut of enterprise profiles and industries, which include really regulated industries these types of as health care and monetary services. The procedure is not only secure, but the separation of the stability perimeter by means of the clean up abstraction of a managed support simplifies the career of securing knowledge and knowledge systems for prospects.
On a last observe, we really like our user teams, our customer councils, and our user conferences. We thoroughly embrace the worth of a vibrant group, open up communications, open up community forums, and open up discussions. Open source is an orthogonal strategy, from which we do not shy absent. For case in point, we collaborated on open up sourcing FoundationDB, and created considerable contributions to evolving FoundationDB more.
However, we don’t extrapolate from this to say there is an inherent benefit to open up source program. We could similarly have made use of a distinctive operational shop and a distinctive product of generating it to go well with our specifications if essential. The FoundationDB case in point illustrates our vital thesis: Open is a great assortment of initiatives and processes, but it’s a single of several resources. It is not the hammer for all nails and is the finest option only in some scenarios.
