MongoDB is a non-SQL document-oriented database where data is stored in BSON format. It is well-suited for write-intensive applications, geo-spatial queries, flexible schemas where requirements may change, and scaling through sharding. Key advantages include very fast writes, no need for migrations when changing schemas, and built-in support for features like sharding, geospatial indexing, and logging to capped collections.

Redis Overview
Redis OverviewHoang Long This document provides an overview of Redis, including its creation, features, and persistence methods. Redis is an open-source, in-memory key-value store that was created by Salvatore Sanfilippo to solve the problem of storing real-time page view data from multiple websites. It features different data types that can be stored as keys, master-slave replication for availability, and two persistence methods: RDB, which takes periodic snapshots of the dataset, and AOF, which logs all write operations to reconstruct the dataset from disk on startup.

進階使用Nodejs 淺談no sql(mongodb)Simon Su This document discusses NoSQL and MongoDB. It introduces NoSQL and its characteristics like being non-SQL, horizontally scalable, schema-less, and eventually consistent. It then covers MongoDB specifically, including that it is open source, a document database written in C++ using BSON. Examples are provided of creating, querying, updating, and deleting documents using Node.js and MongoDB. MapReduce is also introduced as a way to parallel process data across collections. Finally, some well-known uses of NoSQL by companies are listed.
MongoDB Introduction - Document Oriented Nosql Database
MongoDB Introduction - Document Oriented Nosql DatabaseSudhir Patil - MongoDB is a document-oriented, non-relational database that uses JSON-like documents with dynamic schemas, horizontal scaling with sharding and replication, and high performance.
- It is used by many large companies and is a good fit for huge, unstructured data or when dynamic schemas are needed. However, it does not support transactions or have the same data integrity features as relational databases.
- MongoDB can store data in flexible document formats, allows ad hoc queries, and supports common operations like insert, update, delete. Features include replication, sharding, indexing, geospatial queries and MapReduce.
Mongodb @ vrt
Mongodb @ vrtJWORKS powered by Ordina The document discusses how MongoDB is used at VRT (the Belgian public broadcasting organization):
- MongoDB version 2.4.9 is used with a replica set of 1 primary and 4 secondaries and secondary preferred read preference.
- On the application side, JavaDriver 2.12 is used with no ORM, just BasicDbObject and QueryBuilder. Integration testing uses NoSQL Unit to insert test data and check results.
- On the database side, all queries are indexed for performance and the replica set provides eventual consistency suitable for their application. System profiling and query explaining are used to determine useful indexes.
Redis
RedisRamon Wartala Redis is an advanced key-value store that is similar to memcached but supports different value types like strings, lists, sets, and sorted sets. It has master-slave replication, expiration of keys, and can be accessed from Ruby through libraries like redis-rb. The Redis server was written in C and supports semi and fully persistent modes.

Rapid, Scalable Web Development with MongoDB, Ming, and Python
Rapid, Scalable Web Development with MongoDB, Ming, and PythonRick Copeland In 2009, SourceForge embarked on a quest to modernize our websites, converting a site written for a hodge-podge of relational databases in PHP to a MongoDB and Python-powered site, with a small development team and a tight deadline. We have now completely rewritten both the consumer and producer parts of the site with better usability, more functionality and better performance. This talk focuses on how we're using MongoDB, the pymongo driver, and Ming, an ORM-like library implemented at SourceForge, to continually improve and expand our offerings, with a special focus on how3 anyone can quickly become productive with Ming and pymongo without having to apologize for poor performance.

MongoDB by Emroz sardar.
MongoDB by Emroz sardar.Emroz Sardar MongoDB is an open-source, document-oriented database that provides flexible and scalable data storage. It is designed to work with modern application architectures like web applications. MongoDB can replace relational databases for web applications, store semi-structured content like media, and enable real-time analytics. It scales easily through replication and sharding. Documents in MongoDB can contain embedded objects and arrays, which reduces the need for joins compared to SQL databases. Queries in MongoDB are also flexible, allowing queries on fields within arrays or embedded documents.

GDG Cloud Southlake #42: Suresh Mathew: Autonomous Resource Optimization: How...James Anderson Autonomous Resource Optimization: How AI is Solving the Overprovisioning Problem
In this session, Suresh Mathew will explore how autonomous AI is revolutionizing cloud resource management for DevOps, SRE, and Platform Engineering teams.
Traditional cloud infrastructure typically suffers from significant overprovisioning—a "better safe than sorry" approach that leads to wasted resources and inflated costs. This presentation will demonstrate how AI-powered autonomous systems are eliminating this problem through continuous, real-time optimization.
Key topics include:
Why manual and rule-based optimization approaches fall short in dynamic cloud environments
How machine learning predicts workload patterns to right-size resources before they're needed
Real-world implementation strategies that don't compromise reliability or performance
Featured case study: Learn how Palo Alto Networks implemented autonomous resource optimization to save $3.5M in cloud costs while maintaining strict performance SLAs across their global security infrastructure.
Bio:
Suresh Mathew is the CEO and Founder of Sedai, an autonomous cloud management platform. Previously, as Sr. MTS Architect at PayPal, he built an AI/ML platform that autonomously resolved performance and availability issues—executing over 2 million remediations annually and becoming the only system trusted to operate independently during peak holiday traffic.
Challenges in Migrating Imperative Deep Learning Programs to Graph Execution:...
Challenges in Migrating Imperative Deep Learning Programs to Graph Execution:...Raffi Khatchadourian Efficiency is essential to support responsiveness w.r.t. ever-growing datasets, especially for Deep Learning (DL) systems. DL frameworks have traditionally embraced deferred execution-style DL code that supports symbolic, graph-based Deep Neural Network (DNN) computation. While scalable, such development tends to produce DL code that is error-prone, non-intuitive, and difficult to debug. Consequently, more natural, less error-prone imperative DL frameworks encouraging eager execution have emerged at the expense of run-time performance. While hybrid approaches aim for the "best of both worlds," the challenges in applying them in the real world are largely unknown. We conduct a data-driven analysis of challenges---and resultant bugs---involved in writing reliable yet performant imperative DL code by studying 250 open-source projects, consisting of 19.7 MLOC, along with 470 and 446 manually examined code patches and bug reports, respectively. The results indicate that hybridization: (i) is prone to API misuse, (ii) can result in performance degradation---the opposite of its intention, and (iii) has limited application due to execution mode incompatibility. We put forth several recommendations, best practices, and anti-patterns for effectively hybridizing imperative DL code, potentially benefiting DL practitioners, API designers, tool developers, and educators.

DevOpsDays SLC - Platform Engineers are Product Managers.pptxJustin Reock Platform Engineers are Product Managers: 10x Your Developer Experience
Discover how adopting this mindset can transform your platform engineering efforts into a high-impact, developer-centric initiative that empowers your teams and drives organizational success.
Platform engineering has emerged as a critical function that serves as the backbone for engineering teams, providing the tools and capabilities necessary to accelerate delivery. But to truly maximize their impact, platform engineers should embrace a product management mindset. When thinking like product managers, platform engineers better understand their internal customers' needs, prioritize features, and deliver a seamless developer experience that can 10x an engineering team’s productivity.
In this session, Justin Reock, Deputy CTO at DX (getdx.com), will demonstrate that platform engineers are, in fact, product managers for their internal developer customers. By treating the platform as an internally delivered product, and holding it to the same standard and rollout as any product, teams significantly accelerate the successful adoption of developer experience and platform engineering initiatives.

DL frameworks have traditionally embraced deferred execution-style DL code—supporting symbolic, graph-based Deep Neural Network (DNN) computation. While scalable, such development is error-prone, non-intuitive, and difficult to debug. Consequently, more natural, imperative DL frameworks encouraging eager execution have emerged but at the expense of run-time performance. Though hybrid approaches aim for the “best of both worlds,” using them effectively requires subtle considerations to make code amenable to safe, accurate, and efficient graph execution—avoiding performance bottlenecks and semantically inequivalent results. We discuss the engineering aspects of a refactoring tool that automatically determines when it is safe and potentially advantageous to migrate imperative DL code to graph execution and vice-versa.

Enterprise Integration Is Dead! Long Live AI-Driven Integration with Apache C...
Enterprise Integration Is Dead! Long Live AI-Driven Integration with Apache C...Markus Eisele We keep hearing that “integration” is old news, with modern architectures and platforms promising frictionless connectivity. So, is enterprise integration really dead? Not exactly! In this session, we’ll talk about how AI-infused applications and tool-calling agents are redefining the concept of integration, especially when combined with the power of Apache Camel.
We will discuss the the role of enterprise integration in an era where Large Language Models (LLMs) and agent-driven automation can interpret business needs, handle routing, and invoke Camel endpoints with minimal developer intervention. You will see how these AI-enabled systems help weave business data, applications, and services together giving us flexibility and freeing us from hardcoding boilerplate of integration flows.
You’ll walk away with:
An updated perspective on the future of “integration” in a world driven by AI, LLMs, and intelligent agents.
Real-world examples of how tool-calling functionality can transform Camel routes into dynamic, adaptive workflows.
Code examples how to merge AI capabilities with Apache Camel to deliver flexible, event-driven architectures at scale.
Roadmap strategies for integrating LLM-powered agents into your enterprise, orchestrating services that previously demanded complex, rigid solutions.
Join us to see why rumours of integration’s relevancy have been greatly exaggerated—and see first hand how Camel, powered by AI, is quietly reinventing how we connect the enterprise.

- 8. Capped collection for logging ▪ Collection == table ▪ Can be time based or size based
- 9. geo-spatial indexes ▪ Place your Domino’s order to the nearest outlet?
- 10. geo-spatial indexes ▪ db.collection('places').find( {loc: {$near: [50,50], $maxDistance: 10}}).
- 11. Flexible schema "_id" : ObjectId("526a55f14162689cbc0c0000"), "first_name" : "First Name 0", "last_name" : "last Name 0", "add" : "Address number is 0", "company" : "company 0", "employee_id" : "0" "_id" : ObjectId("526a55f14162689cbc0c0001"), "first_name" : "First Name 1", "last_name" : "last Name 1", "add" : "Address number is 1", "company" : "company 1", "employee_id" : “1“, “is_external” : “true”
- 12. Flexible schema ▪ In mySQL, extra space for “is_external” as “nil” for most of the rows which leads to the wastage of space. ▪ No need for the migration
- 13. No migration ▪ Migrations are expensive and time consuming. It increase proportionally to the size of your table ▪ How does a migration happen – Create a temp copy of the table with the migration – Delete the old table – Make temp copy permanent
- 15. In-built support for sharding.
