    Data APIs: Realizing the Future of Data Warehousing

    Data is the currency of business in today’s digital economy, with organizations collecting mountains of data from their customers, products and services. Enterprises are increasingly turning to data warehouses to store this valuable enterprise data and to make it useful and actionable. Data APIs–both GraphQL and REST–are emerging as a tool to power frictionless and high-quality integrations between applications/services and data in enterprise data warehouses. But what exactly is driving this shift toward using APIs on top of data warehouses? In this article, I will talk about the drivers behind the rise of data APIs on data warehouses, challenges with current approaches to building, operating and scaling data APIs and how organizations can address those challenges.

    The Rise of Data APIs

    Data APIs enable organizations to create powerful integrations between applications without having to go through lengthy development cycles or write complex code. As a result, businesses can deliver improved user experiences faster than ever before by quickly connecting disparate applications and services together using intuitive REST or GraphQL endpoints. Because these endpoints are standardized across multiple systems (e.g., REST or GraphQL), developers don’t have to learn new languages or coding techniques every time they want to connect two different applications together. This makes it much easier for developers to work with multiple systems simultaneously while still ensuring that all applications remain connected via one interface–the API endpoint itself.

    Challenges With Current Approaches

    Despite all these advantages provided by Data APIs, there still remain a few challenges that organizations need to consider when building out their own solutions. For example, many existing approaches require manual setup processes, which can be extremely time-consuming and tedious for developers working with multiple systems at once. In addition, many existing solutions only allow for limited query functionality, which means that more complex queries may not be possible without additional coding or manual setup processes being performed. Finally, some existing solutions require an extensive amount of organizational resources in order to build out a full-fledged solution—time that could be better spent on more important tasks like product development or customer service initiatives.

    How Organizations Can Address These Challenges

    Fortunately, there are now tools available that make it easy for organizations to quickly build out powerful data API solutions with minimal effort required from their developers or IT staff members. These tools provide pre-built templates that can be used as a starting point for any integration project while also allowing users to customize their own solution based on specific needs and requirements without having to write any code themselves. Additionally, these tools allow users access to advanced query functions such as joins across multiple tables so they can get the most value out of their databases without compromising either speed or security either. Finally, these tools also include powerful monitoring capabilities so users can ensure that their data APIs remain running smoothly at all times, no matter how much traffic they receive.

    Benefits of Using an API for Integrating Cloud Data Warehouses

    When it comes to integrating cloud data warehouses into your application or service, there are several advantages that come with using an API as opposed to traditional methods such as manual coding or ETL tools:

    • Increased Flexibility: By leveraging an API, you are able to access data from multiple sources quickly and easily without having to manually code every integration yourself. This also allows your application or service more freedom when it comes to accessing additional data sets in the future; all you need is an existing API connection in place.
    • Improved Security: Since APIs are designed specifically for secure communication between different systems, they offer enhanced levels of protection against malicious attacks such as DDoS attacks or unauthorized access attempts. You can also add additional layers of security by implementing authentication protocols like OAuth or JWT tokens on top of your existing API connection.
    • Enhanced Performance: APIs can be designed with specific performance optimizations in mind; this means that you can create custom solutions tailored towards the exact needs of your application or service which will ultimately result in improved end-user experiences and higher engagement rates from customers who interact with your product or service regularly.

    Data warehouses have become an essential part of modern digital businesses due to the sheer amount of valuable enterprise information they store. However, traditional approaches can often lack the flexibility or scalability needed in order for businesses to stay competitive in today’s ever-changing market environment. This is why smart organizations are using data APIs on top of them for quick integration among disparate applications/services along with advanced query capabilities.

    By leveraging tools designed specifically for this purpose, companies can easily overcome current challenges associated with building out their own solutions while still getting maximum bang for their buck when it comes down to successful implementation and operation over the long term.

  • Getting Started With GraphQL APIs

    Getting Started With GraphQL APIs

    GraphQL, a query language for APIs and a runtime for fulfilling those queries with your existing data, is rapidly growing in popularity. According to the latest State of JavaScript survey report, 44.3% of respondents said they had used GraphQL APIs in 2020 compared to only 5% in 2016. Additionally, many Fortune 500 companies now use GraphQL APIs for their backends in production, while top tech companies like Facebook and GitHub use the API technology to improve their product offerings and boost system performance.

    With the ever-changing technology landscape, you might have doubts about adopting GraphQL API for your backend and be unsure how it can improve your current data needs. However, regardless of what language or architecture you are using, GraphQL APIs can help simplify data access, supercharge the product development process, improve application performance and handle complex back-end data scenarios.

    One Unified Endpoint For Your Backend

    One advantage of GraphQL APIs is that they provide a single unified endpoint for your backend to meet both client and general API use cases. A single GraphQL API can handle all the client’s requests and forward them to the correct backend service.

    As companies and their products scale, REST endpoints can become large and incredibly hard to manage. One of the main problems in REST is the N+1 problem, where the client calls the server N+1 times to get N number of resources, mainly because a single REST resource does not provide enough information for the client to operate with.

    Brennan Saeta, an infrastructure engineer at Coursera, cited centralizing REST APIs for simple consumption by the client as one of the reasons why GraphQL API appealed to them.

    GraphQL API hides the complexity of the underlying backend system by aggregating the required data from different sources and providing a simple interface that clients can communicate with through a single resource.

    Improved Application Performance With GraphQL

    GraphQL API improves application performance by reducing JSON payload size and network overhead from multiple API calls. By allowing the client to specify its data requirements, GraphQL APIs eliminate the need for unnecessary generic data being passed from the back end and minimize the number of roundtrips required to retrieve back-end data.

    As companies scale and iterate their products, the data required by different clients and pages changes. In REST API design, when new requirements arise, developers must decide whether to create a new endpoint and have clients make a new request for that data or add more data to an existing endpoint. The first option leads to more server roundtrips, and the second option increases payload size, which can hinder app performance.

    With more applications being accessed over flaky mobile networks and app speed being an important metric for retaining users, minimizing server roundtrips and data transferred over the wire is paramount. Companies like Netflix and Pulley have reported faster page load times and overall app performance after switching to GraphQL APIs.

    With GraphQL APIs, clients receive only the data they specify from the backend server in a single trip, saving network bandwidth and resources.

    Improved System Reliability

    GraphQL API improves system reliability by ensuring that client queries are valid and in sync with the GraphQL schema specification before query execution. GraphQL uses a type system that describes what type of data can be queried from the backend server and in what form it exists. A strongly-typed schema offers enhanced security over REST APIs by preventing breaches like SQL injection and unintentional data leaks, resulting in a more secure and reliable application.

    Type-safety ensures that any breaking changes by the backend server would be caught by clients consuming the data, resulting in less downtime. With GraphQL APIs, you can modify and deprecate API fields while still maintaining backward compatibility. It is easier to know which fields in the API are being used by what clients and which ones are not. With GraphQL, API developers can confidently make changes to the existing APIs without breaking the existing functionality.

    Swiggy, India’s largest food delivery platform, discussed how adopting GraphQL API for their back end enabled them to make changes to their existing APIs without breaking the consumer application.

    GraphQL ensures API consistency, reliability and security, resulting in better system performance.

    Better Developer Experience

    Adopting GraphQL APIs improves the developer experience for both frontend and backend developers. Backend developers want to build APIs that are intuitive and easy to explore and navigate. GraphQL helps with that by reducing the time spent documenting APIs.

    Through a concept known as introspection, GraphQL APIs allow clients to query the schema and discover the resources available on it. With excellent tools and libraries like the GraphiQL IDE, the interactivity for GraphQL API endpoints is much more intuitive for the developer.

    API consumers want APIs that are flexible, easy to integrate and support a variety of client use cases (web, iOS and Android). Because of REST’s inflexibility, it is challenging to create a single endpoint that can meet all of the client’s data requirements. Often the same client has to call multiple APIs to get the data it needs from the backend. Additionally, with REST APIs, frontend developers have to rely on the backend for API specifications before building product features, leading to slower development time.

    Peter Downs, director of engineering at fintech startup Pipe, said choosing GraphQL APIs early on cut their development time by 90%. With GraphQL APIs, frontend and UI developers can quickly and easily iterate on features by simply specifying the data requirements in the GraphQL API, thereby reducing the dependence on backend developers to make changes.

    Getting Started With GraphQL APIs

    The best way to learn GraphQL is by getting your hands dirty and building applications with it. Depending on your language of choice, there are GraphQL libraries in many different languages to help you get started.

    As with any new technology, adopting GraphQL APIs for your back end and building high-performant GraphQL backends requires experience, which is not peculiar to GraphQL alone.

    If your application relies heavily on interconnected data, you aim to develop an API to be used across several clients or are looking for a high-performant API solution for your backend that minimizes bandwidth usage, then GraphQL API is a perfect data layer for your backend.
