Striking a balance with ‘open’ at Snowflake

The relative merits of “open” have been hotly debated in our sector for yrs. There is a perception in some quarters that currently being open is valuable by default, but this watch does not normally entirely take into account the goals currently being served. What issues most to the huge majority of corporations are safety, functionality, costs, simplicity, and innovation. Open really should normally be utilized in provider of all those ambitions, not as the target in alone.

When we create products and solutions at Snowflake, we assess wherever open criteria, open formats, and open source can develop the finest outcome for our buyers. We think strongly in the favourable impression of open and we are grateful for the open source community’s efforts, which have propelled the huge knowledge revolution and significantly extra. But open is not the reply in each instance, and by sharing our imagining on this subject matter we hope to give a beneficial perspective to other individuals making innovative systems.

Open is normally recognized to describe two wide components: open criteria and open source. We’ll look at them just about every in extra element in this article.

Open criteria

Open criteria encompass file formats, protocols, and programming products, which include languages and APIs. Whilst open criteria usually give benefit to users and sellers alike, it’s essential to have an understanding of wherever they provide greater-level priorities and wherever they do not.

File formats

We concur that open file formats are an essential counter to the pretty actual difficulty of seller lock-in. Where we differ is in the assertion that all those open formats are the ideal way to signify knowledge through processing, and that direct file accessibility really should be a crucial attribute of a knowledge platform. 

At very first glance, the skill to specifically accessibility data files in a common, perfectly-recognised format is attractive, but it gets troublesome when the format desires to evolve. Take into account an improvement that allows greater compression or greater processing. How do we coordinate throughout all doable users and purposes to have an understanding of the new format?

Or take into account a new safety ability wherever knowledge accessibility depends on a broader context. How do we roll out a new privacy ability that good reasons by means of a broader semantic understanding of the knowledge to keep away from re-identification of persons? Is it vital to coordinate all doable users and purposes to undertake these improvements in lockstep? What takes place if a person of these is skipped?

Our prolonged experience with these trade-offs presents us a strong conviction about the exceptional benefit of giving abstraction and indirection compared to exposing uncooked data files and file formats. We strongly think in API-pushed accessibility to knowledge, in greater-level constructs abstracting away physical storage facts. This is not about rejecting open it’s about providing greater benefit for buyers. We harmony this with building it pretty easy to get knowledge in and out in common formats.

A very good illustration of wherever abstracting away the facts of file formats noticeably helps finish users is compression. An skill to transparently modify the fundamental illustration of knowledge to reach greater compression translates to storage savings, compute savings, and greater functionality. Exposing the facts of file formats helps make it up coming to difficult to roll out greater compression with out incurring prolonged migrations, breaking improvements, or additional complexity for purposes and developers. 

Similar challenges occur when we assume about enhancements to safety, knowledge governance, knowledge integrity, privacy, and several other spots. The record of databases units presents plenty of examples, like iSAMS or CODASYL, showing us that physical accessibility to knowledge sales opportunities to an innovation lifeless finish. Far more not long ago, adopters of Hadoop located them selves running expensive, elaborate, and unsecured environments that did not supply the promised functionality.

In a world with direct file accessibility, introducing new abilities translates into delays in knowing the positive aspects of all those abilities, complexity for application developers, and, most likely, governance breaches. This is a different level arguing for abstracting away the inner illustration of knowledge to give extra benefit to buyers, while supporting ingestion and export of open file formats. 

Open protocols and APIs

Info accessibility procedures are extra essential than file formats. We all concur that steering clear of seller lock-in is a crucial client priority. But while some think that open formats are the alternative, the weighty lifting in any migration is definitely about code and knowledge accessibility, no matter if it’s protocols and connectivity motorists, question languages, or business logic. Those people who have absent by means of a program migration can likely attest that the subject matter of file formats is a crimson herring.

For us, this is wherever open issues most — it’s wherever expensive lock-in can be prevented, knowledge governance can be maximized, and greater innovation is doable. Focusing on open protocols and APIs is crucial to steering clear of complexity for users and enabling steady, transparent innovation.

Open source

The positive aspects cited for open source include a greater understanding of the technologies, improved safety by means of transparency, lessen costs, and group growth. Open source can supply in opposition to some of these ambitions, and does so mainly when technologies is installed on-premises, but the shift to managed companies enormously alters these dynamics.

When it comes to greater understanding of code, take into account that a innovative question processor is generally developed and optimized above a number of yrs by dozens of Ph.D. graduates. Building the source code out there will not magically make it possible for its users to have an understanding of its internal workings, but there may perhaps be greater benefit in surfacing knowledge, metadata, and metrics that give clarity to buyers.

Another element of this discussion is the want to duplicate and modify source code. This can give benefit and optionality to corporations that can make investments to make these abilities, but we have also found it lead to undesirable effects, including fragmented platforms, significantly less agility to put into action improvements, and competitive dysfunction. 

Greater safety

This has usually been a person of the key arguments for open source. When an corporation deploys application within its safety perimeter, source code availability can indeed enhance self-confidence about safety. But there is a growing recognition of the risks in application provide chains, and elaborate technologies answers normally mixture a number of application subsystems with out an understanding of the entire finish-to-finish impression on safety.

Thankfully there is a greater model, which is the deployment of technologies as managed cloud companies. Encapsulation of the internal workings of these companies allows for quicker evolution and speedy delivery of innovation to buyers. With added concentrate, managed companies can take away the configuration load and reduce the hard work essential for provisioning and tuning. 

Decrease value

Most corporations have acknowledged by now that not having to pay a application license does not essentially mean lessen costs. Aside from the value of maintenance and help, it ignores the value and complexity of deploying, updating, and split-correcting application. Price tag really should be calculated in terms of whole value and price/functionality out of the box. Listed here, as well, managed companies are preferable, eradicating among the other matters the have to have to control variations, operate close to maintenance windows, and great-tune application.


A single of the most strong features of open source is the idea of group, by which a team of users operate collaboratively to enhance a technologies and help a person a different. But collaboration does not have to have to suggest source code contribution. We assume of group as users serving to a person a different, sharing finest procedures, and discussing long run instructions for the technologies. 

As the shift from on-premises to the cloud and managed companies carries on, these subjects of control, safety, value, and group recur. What is fascinating is that the primary ambitions of open source are currently being fulfilled in these cloud environments with out essentially giving source code for everyone—which is wherever we started off this discussion. We have to not drop sight of the sought after results by concentrating on practices that may perhaps no for a longer period be the finest route to all those results.

Open at Snowflake

At Snowflake, we assume about very first principles, about sought after results, about intended and unintended effects, and, most importantly, about what’s finest for our buyers. As this sort of, we do not assume of open as a blanket, non-negotiable attribute of our platform, and we are pretty intentional in picking out wherever and how we embrace it. 

Our priorities are obvious: 

  1. Produce the best levels of safety and governance 
  2. Give sector-main functionality and price/functionality by means of steady innovation and 
  3. Established the best levels of high-quality, abilities, and ease of use so our buyers can concentrate on deriving benefit from knowledge with out the have to have to control infrastructure. 

We also want to ensure that our buyers keep on to use Snowflake since they want to and not since they’re locked in. To the extent that open criteria, open formats, and open source help us reach all those ambitions, we embrace them. But when open conflicts with all those ambitions, our priorities dictate in opposition to it.

Open criteria at Snowflake

With all those priorities in mind, we have entirely embraced common file formats, common protocols, common languages, and common APIs. We’re intentional about wherever and how we do so, and we have invested heavily in the skill to leverage the abilities of our parallel processing engine so that buyers can get their knowledge out of Snowflake speedily really should they have to have or pick to. However, abstracting away the facts of our small-level knowledge illustration allows us to continually enhance our compression and supply other optimizations in a way that is transparent to users. 

We can also advance the controls for safety and knowledge governance speedily, with out the load of running direct (and brittle) accessibility to data files. Likewise, our transactional integrity positive aspects from our level of abstraction and not exposing fundamental data files specifically to users. 

We also embrace open protocols, languages, and APIs. This consists of open criteria for knowledge accessibility, traditional APIs this sort of as ODBC and JDBC, and also Relaxation-centered accessibility. Likewise, supporting the ANSI SQL common is crucial to question compatibility while offering the energy of a declarative, greater-level model. Other examples we embrace include enterprise safety criteria this sort of as SAML, OAuth, and SCIM, and a lot of technologies certifications.

With proper abstractions and advertising and marketing open wherever it issues, open protocols make it possible for us to shift quicker (since we do not have to have to reinvent them), make it possible for our buyers to re-use their knowledge, and help fast innovation due to abstracting the “what” from the “how.” 

Open source at Snowflake

We supply a smaller amount of factors that get deployed as application answers into our customers’ units, this sort of as connectivity motorists like JDBC or Python connectors or our Kafka connector. For all of these we give the source code. Our target is to help greatest safety for our buyers, and we do so by providing our main platform as a managed provider, and we enhance the peace of mind for installable application by means of open source.

However, a misguided application of open can develop expensive complexity as an alternative of small-value ease of use. Giving steady, common APIs while not opening up our internals allows us to speedily iterate, innovate, and supply benefit to buyers. But buyers can’t create—deliberately or unintentionally—dependencies on inner implementation facts, since we encapsulate them at the rear of APIs that adhere to stable application engineering procedures. That is a important advantage for both of those sides, and it’s crucial to retaining our weekly cadence of releases, to steady innovation, and to resource performance. Shoppers who have migrated to Snowflake tell us regularly that they recognize all those alternatives.

The interface to our entirely managed provider, operate in its possess safety perimeter, is the agreement in between us and our buyers. We can do this since we have an understanding of each ingredient and devote a wonderful quantity of assets to safety. Snowflake has been evaluated by safety teams throughout the gamut of business profiles and industries, including highly regulated industries this sort of as healthcare and financial services. The program is not only secure, but the separation of the safety perimeter by means of the clean abstraction of a managed provider simplifies the occupation of securing knowledge and knowledge units for buyers.

On a closing be aware, we enjoy our user groups, our client councils, and our user conferences. We entirely embrace the benefit of a lively group, open communications, open boards, and open conversations. Open source is an orthogonal concept, from which we do not shy away. For illustration, we collaborated on open sourcing FoundationDB, and built major contributions to evolving FoundationDB additional. 

However, we do not extrapolate from this to say there is an inherent benefit to open source application. We could equally have utilized a various operational retail store and a various model of building it to accommodate our needs if needed. The FoundationDB illustration illustrates our crucial thesis: Open is a wonderful assortment of initiatives and procedures, but it’s a person of several applications. It is not the hammer for all nails and is the finest option only in some situations.
