Since 2008, Canara HSBC Life Insurance has focused relentlessly on bringing a fresh perspective to an industry known more for stability and conservatism rather than innovation. Since its inception in 2008 as a joint venture between Canara Bank and HSBC Insurance, Canara HSBC Life Insurance has strived to differentiate itself from the competition through enhanced customer interactions, launching cutting-edge digital products, and integrating digital services that cater to the evolving needs of customers. For the past six years Chief Operating Officer, Mr. Sachin Dutta, has been on a mission to bring this customer-first mindset to the digital products and touchpoints his team creates. Speaking at MongoDB’s annual .local developer conference in Delhi, Dutta outlined Canara HSBC Life Insurance’s ongoing digital transformation journey, and how his team's focus on customer success and business efficiency led them to work with MongoDB for improved efficiencies and results. “I truly value the partnership we have with MongoDB. We are building a future-ready organization, and this partnership clearly helps us achieve our aim of reaching the last mile possible in customer servicing. Mr. Sachin Dutta, Chief Operating Officer, Canara HSBC Modernizing the architecture and driving developer efficiency Canara HSBC’s digital transformation was centered on three technical pillars: the cloud, analytics, and mobility. The company focused on creating a more integrated organization and automating manual processes within the system. “We try to remove human intervention with a life insurance policy delivered in seconds and claims that are settled virtually in seconds,” Dutta says. To get there, Canara HSBC Life Insurance had to move on from its existing architecture, which required multifaceted changes and several new implementations: Monolithic applications made alterations a time-consuming process A reliance on rigid relational databases prolonged development timelines, forcing developers to spend time wrangling data when they could be building better products for customers. The fully on-premises system had supported the organization in the past but required future-proofing to support growth and deliver a better customer experience. Because of this valuable development time and money were spent managing, patching, and scaling databases, rather than getting new products into the hands of customers. These technical issues impacted the speed of business, particularly during month-end and year-end data processing, when the volumes were high. In addition, batch processing stood in the way of creating the real-time availability of information customers wanted. Dutta and his senior team also realized that their existing infrastructure would make it more challenging to find the right talent in the market, as the existing infrastructure was increasingly becoming outdated. Dutta realized early on that, in order for Canara HSBC to attract and retain the best and brightest developers, the insurer had to offer the chance to work with the latest technologies. Platforms like MongoDB would be integral to this effort. “I want to create an organization that is attracting talent and where people start to enjoy their work, and that benefit then gets passed on to the customers, ” Mr. Dutta says. Looking to overhaul its existing infrastructure, Canara HSBC Life Insurance wanted to move fast and hire the talent required to best serve its end customers. Dutta summarized the situation succinctly: "We found that some of those relational structures that had worked for us would not take us through the next 10 years.” Migrating to a secure, fully managed database platform After evaluating the solutions on the market, the team decided to transition from their existing on-premises relational databases, like IBM DB2, MySQL, and Postgres, to MongoDB Atlas. In the last six years of my work, I’m pleased to say that MongoDB has seamlessly integrated all the processes in the backend. We migrated from a completely legacy-based setup to the new fully managed MongoDB service to enhance IT productivity Mr. Sachin Dutta The first stage of the journey was moving from monolithic applications and relational databases to a microservices architecture. With its flexible schema and capabilities for redundancy, automation, and scalability, MongoDB served as the best partner to help facilitate the transition. Next, the team moved to modernize key parts of the business, such as underwriting, freeing their data to power more automation in straight-through processing (STP) of policies and faster claims processing. The adoption of a hybrid cloud model shifted Canara HSBC Life Insurance away from on-premises databases to MongoDB Atlas. As a fully managed cloud database, MongoDB Atlas solves issues related to scalability, database management, and overall reliability. MongoDB Atlas is also cloud agnostic, giving the insurance company an option to work with Azure, AWS, and Google Cloud. Mongo Atlas’ BI Connector bridged the gap between MongoDB and traditional BI tools. This seamless integration allowed Canara HSBC Life Insurance to deploy its preferred reporting tools and, when coupled with MongoDB Atlas’ real-time analytics capability, made batch processing a thing of the past. Halving delivery times and driving business efficiencies Moving to MongoDB Atlas has had a profound impact on the breadth of digital experiences Canara HSBC Life Insurance can offer customers and the speed at which new products can be developed. Something that used to take months, with the implementation of our new tools could be completed in a couple of weeks or days Mr. Sachin Dutta And it’s not only the customer experience and product delivery that has benefited from the partnership. Canara HSBC Life Insurance has also realized substantial efficiency gains and savings as a result of working with MongoDB. We are leveraging artificial intelligence as a core capability to predict human behavior and auto-underwrite policies wherein around half of the policies issued today are issued by the system Mr. Sachin Dutta Highlighted results include: Straight-through processing (STP) surged from 37% to an impressive 60%. This is set to increase further with AI/ML integrations and rule suggestions. Policy issuance turnaround time improved by 60%. Efficiency in operations led to a 20% cost-saving per policy issuance. Canara HSBC experienced 2x top-line growth due to seamless integration with analytical tools. Looking ahead, Canara HSBC Life Insurance has already outlined three key areas where the MongoDB partnership will grow. First, Dutta wants to take advantage of MongoDB Atlas’ flexible document data model to collect and organize data on customers from across the business, making MongoDB Atlas the sole database at Canara HSBC Life Insurance and creating a true customer 360 data layer to power sophisticated data analytics. In financial services, this capability is referred to as know your customer (KYC). “We want to build a data layer that provides a unique experience to the customer after getting to know them,” he says. “That’ll help the company generate better NPS scores and retain customers.” Second, the adoption and integration of AI and machine learning tools also factor heavily into future plans. MongoDB Atlas, with its flexible schema, compatibility with various machine learning platforms, and AI-specific features — such as Vector Search and storage — is a good fit for the company. In Dutta's words, "We are going to scale up and capture the GenAI space.” Last, Dutta wants to take advantage of the MongoDB Atlas SQL interface, connectors, and drivers to augment business intelligence for reporting and precise SQL-based report conversions.

MongoDB is expanding its business in New Zealand to help Kiwi organisations build modern applications and take advantage of the AI opportunity that exists today. With hundreds of customers already in Aotearoa, including Pathfinder, Rapido, and Tourism Holdings, we're continuing to hire and invest to continue to grow our community in the country. Powering the next generation of modern applications Interest and excitement in AI, and particularly generative AI, has exploded. With a proud history of Innovation, it's not a surprise that many New Zealand companies are early adopters of this incredible technology. In fact, an AI Forum report has revealed that AI has the potential to increase New Zealand's GDP by as much as $54 billion by 2035. No matter what you think of the veracity of those bold predictions, one thing is sure: Almost every company is trying to figure out how to take advantage of data and software, to help them build better products, more efficiently and more quickly. Jake McInteer speaking at MongoDB.local Auckland As organisations transform into digital-first businesses, they’re faced with a growing list of application and data requirements. Modern applications are complex – they need to handle transactional workloads, app-driven analytics, full-text search, AI-enhanced experiences, stream data processing, and more. Companies are being asked to do this all while reducing data infrastructure sprawl, complexity and often also cut costs. What we are seeing globally is our developer data platform solves this challenge and complexity since it integrates all of the data services organisations need to build modern applications in a unified developer experience. Additionally, we also allow our customers to easily run anywhere in the world with over 110+ locations making us uniquely placed to enable Kiwi companies to adapt to a multicloud future. We also have strong local partnerships with all three cloud hyperscalers, all of which plan to open new cloud regions in New Zealand in the coming years. With the support of our cloud partners, in New Zealand we've already seen great adoption of MongoDB Atlas, including the largest established enterprises, through to cutting-edge startups. Here are a couple of examples. Pathfinder: Protecting vulnerable children Pathfinder, headquartered in Auckland, is a global leader in software development specialising in protecting vulnerable children. The company's mission centres on empowering law enforcement agencies with state-of-the-art technology, meticulously designed to combat the reprehensible crime of child exploitation. "We are committed to delivering investigators the most advanced tools. We cannot accept delays in removing a child from harm due to investigations being overwhelmed by large amounts of disparate data. In situations where every minute impacts a child's well-being, these tools must enable investigators to swiftly navigate data challenges, and rapidly apprehend perpetrators" said Bree Atkinson, CEO of Pathfinder Labs. Pathfinder’s Paradigm service is being built on MongoDB Atlas, running on AWS, and takes advantage of the wider developer data platform features in order to enable the next generation of data-driven investigative capabilities. By using MongoDB Atlas Vector Search, a native part of the MongoDB Atlas platform, the Pathfinder team are also able to match images and details within images (such as people and objects), classify documents and text, and build better search experiences for their users via semantic search. This enables Paradigm to efficiently aid law enforcement in identifying victims and apprehending offenders. Bree Atkinson, CEO of Pathfinder Labs, and Peter Pilly, DevOps Architect at Pathfinder Labs, with the MongoDB team in Auckland at the recent .local event "MongoDB Atlas allows our team to focus on our strengths: developing outstanding technology. It works with us not against us, enhancing integration which enables us to build better user experiences," said Peter Pilley, DevOps Architect at Pathfinder Labs. "Take MongoDB Atlas Vector Search, for example. Before MongoDB, we would have needed to incorporate multiple tools to achieve that functionality. Now we can handle it all from a single platform removing complexity and architecture that wasn't needed. With MongoDB Atlas, we're able to make data-driven decisions swiftly, boosting our productivity and decision-making speed." Peter's team at Pathfinder also uses MongoDB's performance advisor. They say it's like having an extra team member who suggests the best indexes for accessing their data, which is critical in an industry where getting to a specific piece of data could make all the difference. Rapido: Optimising B2B revenue and distribution Rapido has been utilising MongoDB Atlas for over five years. The team was originally part of MongoDB for Startups, a programme that offers startups free credits and technical advice to help them build faster and scale further. Their eagerness to adopt new technologies has enabled them to effectively harness MongoDB Atlas's evolving features. Working with the Accredo ERP system, Rapido has harnessed MongoDB Atlas to innovate in business-to-business (B2B) transactions. Using features like MongoDB Atlas Vector Search, the 'moreLikeThis' operator, and MongoDB App Services, they've transformed business interactions, offering precise product recommendations and improved real-time visibility via change streams. Rapido's platform, which has processed orders collectively worth more than $100m to date, is essential for many wholesale businesses in New Zealand. Adam Holt, CEO of Rapido, summarises their experience: "Our journey with MongoDB Atlas has been transformative. By building on a cohesive developer data platform, we don't need to bolt-on and learn special technologies for every requirement. Continuously integrating new features keeps our platform advanced in the fast-paced B2B market. It's about leveraging technology to innovate and deliver better solutions to our clients." MongoDB expands in Aotearoa The increased demand from Kiwi organisations who are looking to innovate faster and take advantage of cutting-edge technologies, like AI, means MongoDB is now doubling down on its New Zealand footprint. Earlier this month, MongoDB established its local operations in Aotearoa, New Zealand. Jake McInteer, a native Kiwi, has officially transferred from MongoDB’s Australia business to lead the organisation in New Zealand. MongoDB already has a large, engaged community, more than 200 customers, and an extensive partner network. CEO of Lumin Max Ferguson presents at the Christchurch MongoDB user group We are incredibly excited about the opportunity to invest in and contribute to the Kiwi tech ecosystem, both to support local companies and help kiwi startups like Lumin and Marsello as well as established companies like Tourism Holdings, Figured, and Foster Moore. To support our growth, we have roles open on our Sales and Solutions Architecture team.

内容无处不在。 无论消费者寻找什么，也无论消费者所处任何行业，找到内容并不困难，关键在于如何找到对应的内容。而这就是 Concured 专注的领域。 Concured 是一家来自蒙特利尔的 AI 初创企业，致力于协助市场营销团队对标受众，有的放矢地打造网站和销售内容；同时，帮助内容营销团队脱颖而出，加速基于洞察驱动的内容个性化。 2015 年，首席执行官 Tom Salvat 创立 Concured，旨在助力内容营销机构更深入地理解受众需求，交付更具影响力的内容。 Built with MongoDB 栏目采访了公司成立约一年后加入公司的首席技术官 Tom Wilson，话题围绕 Concured 的人工智能使用情况、Wilson 加入 Concured 的过程以及公司未来的发展。 Built with MongoDB： Concured 是做什么的？ Tom Wilson：Concured 是一家软件公司，以过去 5-10 年间发展的人工智能技术为基础，帮助市场营销机构了解如何撰写具体领域的宣发物料，发掘自身内容亮点，把握竞争对手以及行业宣发现状。进而打造个性化的客户网站使用体验，最大化内容投资收益比。 Concured 已成功推出一套内容推荐系统，能够为每位访问者提供针对性服务。这套系统注重用户隐私，不使用任何第三方 cookie 或用户监视技术，完全基于网站用户的操作，通过访问者的点击行为勾勒出其兴趣领域。随着用户的兴趣和目的逐渐清晰，这套系统会尝试推荐新的阅读内容，比如博文、产品介绍或其他类型的内容。 Built with MongoDB：您刚刚提到了人工智能，那么 Concured 是如何使用人工智能的呢？ Wilson：我们运用人工智能的场景有很多。有别于其他个性化系统，Concured 的卖点之一是不需要过长的整合期，也无需在日常管理中进行维护。实现的途径是借助 AI 机器人剖析客户网站的内容，发掘相关性，提取文本、标题和其他所有相关元数据，然后完成自动索引。 我们的系统利用先进的自然语言处理 (NLP) 技术，为每个文档生成语义元数据，在多维空间中与特定点相对应。另一方面是理解其中的关键实体，以及同一个网站中某一篇特定文章与其他文章之间的关系。我们利用 AI 支持的网络爬虫找到的所有内容都会自动附上海量元数据。 [图片] Built with MongoDB：AI 并不总是 100% 准确，您在 Concured 打造的 NLP 的准确度怎么样呢？ Wilson：以内容推荐系统而言，很难断定什么是最佳推荐，因为即便是同一个人，根据日期或网络操作的不同，推荐也会有所变化。例如一些知名的推荐系统，如 Netflix、Amazon 和 Spotify，总是在猜我们接下来想看什么，但却没有一个是对应的答案。 正因如此，绩效评价变得非常困难。所以，我们采取的方式是不提供 100% 对应的答案，而是通过改变算法，来看访问者是否会点击更多的文章，是否会进入网站运营商定义的目标页面，比如产品页面或注册表单。在网站访问人员中，最终执行该操作的人数比例越高，说明推荐系统越出色。我们可以对比客户在启用 Concured 个性化系统前后的网站成功率。截至目前，我们已经看到 2-3 倍的提升，算法一直在完善中。 Built with MongoDB：您是何时加入到 Concured 团队的？ Wilson：当时公司已经得到第一笔来自外部的巨额投资，条件之一是引入一位专业的首席技术官。这种情况在企业初创期比较常见，投资方想要介入企业架构，把控资金流向，减少鲁莽行事。所以，有些企业将其戏称为“家长式监督”。我不知道这算不算是我的角色。不过虽然当时团队已经很强大，但我还是从架构入手，从根上上确保我们能够实现后续的目标，以及更长期的战略规划和技术愿景。 Built with MongoDB：您的团队是如何选择 MongoDB 的？ Wilson：我加入时，团队已经在使用 MongoDB。加入后的几个月里，我们讨论过是否要换用结构化的数据库，并且必须制定出一项决议。所以我才参与其中，经过深思熟虑，决定继续使用 MongoDB。事实证明是一项完全正确的决议，有利于我们实现最初的愿景。同时，我们将弃用 Google Cloud Platform 上的社区版本，换用 MongoDB Atlas Serverless。令人欣喜的是，因为新平台无服务器，我们将不再需要管理各种机器，还能够使用 Atlas 上的文本搜索功能，顺便简化一下我们的技术堆栈。作为一家企业，就我们当下所处的位置以及未来五年的发展方向而言，MongoDB 始终是我们正确的选择。 Built with MongoDB： Concured 的未来是什么样的？ Wilson：就在我们交谈的过程中，未来已经被书写。此时此刻，越来越多和我们大客户有着相同需求的企业正在找到我们。这些企业那些有着海量、已存档的内容，需要继续从中盈利，继续发布更多内容。无论是否是大型企业，比如咨询或金融服务行业或传统的出版商，确定的一点是，以相应的 KPI 为基准，产出利益最大化的对应内容。 Built with MongoDB：您收到的最好反馈是什么？ Wilson：我的团队给我的一条正面反馈，是说我有担当。如果他们遇到问题，我会出手解决或者减少阻力，这样他们就可以全力以赴解决问题。这是我的人生观：如果你用心领导团队，事情就会自然顺利推进。 对于任何投资内容宣发的企业而言，最大化投资回报都是无可争议的商业诉求。

什么是MongoDB分片？ 分片是一种将数据分布或分割到多台计算机上的方法。相较于单个计算机，分片技术允许您进行水平扩展，这在大型现代工作负载的场景下是非常有用的。 水平扩展，也称为横向扩展，是指添加计算机来共享数据集和负载。水平扩展允许进行接近无限的扩展，以处理大数据和强烈的工作负载。 通过分片实现横向扩展 通过分片，您可以自动将MongoDB数据库跨多个节点和区域进行扩展，以处理写入密集型工作负载、不断增长的数据大小以及数据存储要求。 使用MongoDB的分片，您可以在应用程序增长超出单个服务器的硬件限制时，在无需增加应用程序复杂性的情况下，无缝地扩展数据库。 为了响应不断变化的工作负载需求，可以在分片之间迁移文档，并随时向群集中添加或删除节点 - MongoDB将自动根据需要重新平衡数据，无需手动干预。 分片的好处 分片允许您将数据库扩展以处理几乎无限的负载增加。它通过增加读/写吞吐量和存储容量来实现这一点。具体来说： 增加的读/写吞吐量：通过将数据集分布到多个分片上，您可以利用并行处理来增加读/写的吞吐量。假设一个分片可以每秒处理一千次操作，每增加一个分片，您将多获得额外的一千次每秒的吞吐量。 增加的存储容量：同样地，通过增加分片的数量，您还可以增加总体的存储容量。假设一个分片可以容纳4TB的数据。每增加一个分片，您的总存储容量将增加4TB。这样可以实现接近无限的存储容量。 数据本地性：区域分片允许您轻松创建分布式数据库，以支持地理分布的应用程序，并通过强制数据在特定区域内驻留的策略来实现。每个区域可以有一个或多个分片。 MongoDB中的分片策略 大多数分布式数据库在处理数据分布时，是通过简单地对主键值进行散列，将数据随机分布在集群节点中。这在查询跨节点的数据时会带来性能损失，并且在需要将数据本地化到特定区域时会增加应用程序的复杂性。 MongoDB 可以提供多种分片策略，提供对于数据分布更好的方法。。数据可以根据查询模式或数据位置要求进行分布，从而在各种工作负载下实现更高的可扩展性： 范围分片。文档根据分片键值分区到分片上。分片键值彼此接近的文档可能位于同一个分片上。这种方法非常适用于需要优化基于范围的查询的应用程序，例如将特定区域所有客户的数据放置在特定分片上。 散列分片。文档根据分片键值的MD5散列进行分布。这种方法保证了写入在分片上的均匀分布，通常对于摄取时间序列和事件数据流是最优选择。 区域分片。提供了开发人员定义在分片群集中数据放置的特定规则的能力。 MongoDB Atlas中的全局群集 完全托管的云数据库服务MongoDB Atlas允许您使用可视化用户界面或Atlas API快速实现区域分片。您可以轻松创建分布式数据库以支持地理分布的应用程序，并通过强制在特定区域内存储数据的策略来实现数据存储。 使用阿里云MongoDB 分片集群为始终在线、全球分布式的写入应用程序提供服务 要确保充分发挥分片的优势，您需要遵循一系列最佳实践。 确保分片键的均匀分布 当读取和写入的分片键不均匀分布时，操作可能会受限于单个分片的容量。当分片键均匀分布时，没有单个分片会限制系统的容量。 避免散布-汇集查询用于运营工作负载 在分片系统中，不能基于分片键进行路由的查询必须广播到所有分片进行评估。由于这些查询涉及每个请求的多个分片，随着添加更多分片，这些查询不会呈线性扩展，并且需要额外的开销来合并来自多个分片的结果。您应该在查询中包含分片键，以避免散布-汇集查询。 这一规则的例外是大型聚合查询。在这些情况下，散布-汇集可以是一种有用的方法，因为它允许查询在所有分片上并行运行。 在适当的时候使用基于散列的分片 对于发出基于范围的查询的应用程序，基于范围的分片是有益的，因为操作可以路由到最少的分片，通常是一个分片。然而，基于范围的分片需要对数据和查询模式有很好的理解，在某些情况下可能不切实际。 基于散列的分片确保读取和写入的均匀分布，但不提供高效的基于范围的操作。 预分割和分发分片 在创建新的分片集合以加载数据时，首先做集合的预分片，并将它们均匀分布在所有分片上，然后再加载数据。对于基于散列的分片，您可以使用numInitialChunks来自动执行此操作。 下一步 以上就是MongoDB 性能最佳实践中关于分片的内容。接下来我们将介绍事务相关的实践。
